A Dangerous Route in Need of An Alternative: US 129 from Ranger, NC to Maryville, TN

U.S. 129 has reached mythical status for mulleted middle-aged men in Harley's and younger guys in sports bikes shooting the 318 hairpin turns between Robbinsville, NC and Knoxville, TN, but it is a very poor location for a U.S. highway.  A quick Google search, in fact, does not even remotely recommend that U.S. 129 traffic even use that way at all to reach Maryville, TN en route to Knoxville from where it joins U.S. 64 in Ranger, NC.  Nonetheless, the highway that is popularly known as "The Tail of the Dragon" became enough of an issue that a proposal surfaced in the early 2000's to tear it all up for an interstate, I-3.  The interstate proposal was so unpopular that it basically got canceled, but that does not mean a better route is needed: just not there.

Seemingly endless hairpin curves in steep terrain greet drivers of U.S. 129 between Tapoco, NC and Chilhowee Lake in Tennessee.  While it provides unparalleled thrills for motorcycles, it is not such a thrill for through traffic.  Trucks are advised against using this route, and it is mostly useless as a through route for all but tourists and residents of Graham County, NC.  Note here in this image that the road is starting to slip toward Calderwood Lake.  The terrain here drops around 300'-400' on the right.  Photo from Google Street View.

The funny thing is, this is not truly a fixable highway.  It is located in very steep terrain with unstable and sulfuric Anakeesta rock.  It is also a dangerous passage along deceptively deep reservoirs holding back the Little Tennessee River, and it wiggles around very high mountains.  The damage building a modern four-lane road through there would cause would be incalculable.  This includes frequent landslides due to the massive cut and fill that would be required and the risk of poisoning a significant water source from the leeching of sulfuric compounds from the Anakeesta Rock.  In addition, hardly anybody wants any more interstates book-ending the Smokies: even the two-lane park road planned along Lake Fontana (Lake Shore Drive) was finally canceled a decade ago that was designed to replace a long-abandoned state highway (NC 288).  Google's simple map logarithm proves that this road should not even be U.S. 129 at all.  Politics yet again favored an unsuitable mountain crossing elevating a torturous mountain back road into a lengthy section of a major U.S. highway with a long and pointless overlap through Cherokee County, NC.  Lessons should have been learned from the costly disaster that I-40 was when it was slammed through Pigeon River Gorge, but the fix for this road is perfectly clear.

What Google thinks is that U.S. 129 is not the best way to Knoxville.  Even with the less than desirable conditions on TN 68, it is still a better and safer road than U.S. 129.  This is why perhaps U.S. 129 should be moved to the blue highlighted route shown.

Looking at this, it is obvious something needs to be done to change this: U.S. 129 needs to be moved.  For novelty purposes, keeping an alternate route of U.S. 129 along the existing road is an acceptable option.  Re-designating the entire route as U.S. 129 Alt from it current junction with U.S. 64/74 in Ranger, NC to its junction with U.S. 411 near Maryville is certainly an acceptable approach, and it keeps the U.S. 129 designation without marketing it to travelers as a major route.  Relegating it to a state highway is also an option.  While Tennessee can easily do this by revealing hidden TN 115, it is not so clear what to assign it in North Carolina since the original route number 108 as well as 115 are both accounted for elsewhere.  It is also bound to be unpopular due to the tourism that U.S. 129 on its current route attracts.  Perhaps the numbers should be switched so that NC 294 is reassigned to existing U.S. 129 north of U.S. 19/74 and Tennessee likewise renumbers TN 294 in Livingston to assign it instead to existing U.S. 129 so that it is all Highway 294 from U.S. 411 to U.S. 19/74.  I guess a public hearing should be conducted where they get to choose between NC/TN 294 and U.S. 129 Alt.

As to where the new U.S. 129 should go, the logical route is painfully obvious, and it is clearly marked in the map in light blue above.  This new route would be divided into the following segments:

  1. Overlap with U.S. 64/74 west from Ranger, NC to NC 294
  2. All of NC 294 from U.S. 64/74 to the Tennessee State Line
    • NC 294 would be decommissioned along its current route
    • The number 294 would be available to assign to swap with existing U.S. 129 north of U.S. 19/74 to the Tennessee State line
  3. Continuation of U.S. 129 onto TN 123 with 123 relegated to secret status from the state line to TN 68
    • A relocation of the junction of TN 68 and TN 123 is highly advised and is described further shortly
  4. The new route then turns onto and follows TN 68 from TN 123 to U.S. 411 (TN 33) in Madisonville
  5. U.S. 129 then overlaps U.S. 411 from TN 68 in Madisonville to the current junction of U.S. 129 (TN 115) southwest of Maryville.


TN 68 and NC 294 share a significant problem: while some spot upgrades have occurred over the years to streamline the hairpin turns caused by the ruggedness of the terrain, these are both steep and winding mountain roads through remote areas.  It won't be as simple as slapping a U.S. 129 shield on the new route: some improvements will have to be made.  One of those that is glaring is the junction of TN 68 and TN 123 with a peculiar movement favoring TN 123.  This movement requires TN 68 traffic at present to make a diagonal left turn, and if U.S. 129 was routed in from the opposite direction, it would force traffic to make a sharp right (or left southbound) to continue on what would be U.S. 129.  In fact, a closer look at Google has projected U.S. 129 traffic directed onto county-maintained Runion Road: a narrow, winding road that will need to be realigned and upgraded to highway standards to better align TN 68 to TN 123 just west of the state line.  A quick look at Runion Road reveals a paved cowpath that will have to be substantially rebuilt meaning that the reworking will take awhile.  This will drastically change the highways through the Turtletown community, if built.

The sharp switchback required to go from NC 294 to TN 68 north has resulted in Google routing through traffic onto an unsuitable county road known as Runion Road.  For U.S. 129 to go this way, Runion Road will need to be reconstructed and intersections realigned for it to work.

Here, Runion Road is straightened out with intersections realigned to make the new U.S. 129 the primary movement.  Because of this, it might make sense to also move TN 68 onto existing TN 123 to meet at the junction with current Runion Road.  While distance-wise it makes sense (and I would personally prefer it) to have TN 68 remain intact on the upper left, the reality is that the through movement is TN 123 and that it makes more sense to turn that section into a county road or short secondary route.  On the other hand, most of TN 123 would be decommissioned with exception to an unsigned portion between the relocated TN 68 and the state line.

The unfortunate thing about TN 68 is that somehow this highway has been ignored for substantial upgrades and is actually worthy of a study for a major relocation itself.  It is an incredibly scenic drive, and a side of me does not want to see it changed, but the fact is that this is the most suitable route to provide an inter-mountain connection compared to many other alternatives.  In fact, a realistic long-term prospect is to relocate I-75 onto this corridor through an interstate-grade road forking off of the current I-75 near Knoxville and following existing TN 68 south to meet the current U.S. 76/GA 515 west of Blue Ridge.  The existing GA 515 would then over a period of many years have intersections removed, interchanges constructed, and be upgraded to interstate standards including a new eastern by-pass of Ellijay and a shifting of the highway to create frontage roads so that the existing highway can become fully limited-access up until where the road is currently I-575.  I-575 would then revert into part of the new I-75.

The current route of I-75 steers traffic west/northwest.  While it has served its purpose well for many decades, it is increasingly congested and without a viable alternative.

Currently, the proposed route offers no time savings, and is only slightly shorter, but this is considering that on the Tennessee side, the road needs significant straightening and realignment.  That could cut as much as 15-20 miles off of the distance and provide a viable alternative if the Georgia side is upgraded to full freeway.  

In the short term, however, efforts should be made to straighten out the worst of the kinks.  While improvements for NC 294 are not as dire since significant investment has gone into upgrading the road, TN 68 is a different story.  Itself, TN 68 is 50 miles of hairpin turns between TN 123 (the Tennessee extension of NC 294) and the Tellico Valley (junction of TN 165 in Tellico Plains).  Large sections of road will either need to have the curves smoothed or the entire highway relocated to a better alignment.  In fact, the current condition of the road proves to be a major barrier between the Copper Basin (Copperhill) and Tennessee Valley.  On one hand, whatever improvements are made should be incorporated into a design that can be eventually upgraded to an interstate highway (super 2 or two lane on 4 lane right-of-way).  On the other hand, improvements should be minimal enough so that the existing road can remain in service as an alternate route when an interstate replacement is one day built.

Areas like the Hiwassee River crossing show that significant straightening of the road would greatly shorten the distance and increase the speed of the route.  On the right is a series of hairpin turns and switchbacks along the existing TN 68.  The proposed potential route on the left involve hill cuts and a high bridge over the Hiwassee River to straighten out this serpentine section.  Even if it not built to interstate standards or ever considered for a true APD corridor, simply relocating and straightening out the route as a two lane highway with passing lanes would greatly improve access to the area.  


In order to finance construction of a new highway along TN 68 and GA 5 from Blue Ridge, GA to Madisonville, TN it is going to need a significant federal investment.  As it presently stands, funding for this corridor has been sparse at best.  It took 35 years just to even get the Copperhill/McCaysville By-Pass funded, and the project was scaled down from a four lane to a two lane!  Obviously, moving U.S. 129 will highlight the importance of the corridor further north, but initial improvements will mainly be to improve safety and connectivity.  Nonetheless, the delays in upgrading TN 68 pale in comparison to the delays in completing Corridor K, a very emotionally charged project that will likely only be built if public input is pretty much made non-existent.  Perhaps instead, funding can be steered to a corridor less emotionally charged and less scenic.  Corridor K travels through some of the most pristine country in the east as it traverses two deep gorges: Nantahala and Ocoee.  Ocoee Gorge is a significant treasure that people fear will be destroyed by construction of a new highway, but at present there is no suitable alternative.  Since GA 2 was canceled in the 1970's, and no other east-west links exist in the area, perhaps a high speed roadway running from the Georgia State Line to I-75 near Sweetwater would help alleviate some of these issues.  Think of how I-26 took pressure off of I-40 even though it goes in a more northerly direction and further east.  It is the same case with TN 68.

While not part of the U.S. 129 change, upgrades to TN 68 would overall be a very challenging project.  The area of Harbuck in particular is a squeeze point where either extensive cut and fill and disruption will be required in the Harbuck community or two tunnels will need to be constructed under Stansbury Mountain.  This is part of why building the road initially with only one carriageway (super 2) might be beneficial.  A tunnel would be half the cost if it's three lanes wide vs. two three lane wide tunnels.  Ideally, most of current TN 68 is kept intact as an alternate route if a new highway is constructed and kept on-system as a secondary state route.

Even if nothing like an interstate grade road is ever built, it would be a good idea to at least design an improved TN 68 that has the potential to become that.  Design it with right-of-way for a six lane highway with limited access on entirely new location with land set aside for future interchanges would be a start.  Considering that a potential of as much as three tunnels are needed, and significant cut-and-grade is needed, it is not a cheap project.  A significant investment was already made to rebuild TN 68 north of Tellico Plains, and this would simply be a continuation of that project giving a faster, more direct link between Tennessee's most geographically remote cities of Ducktown and Copperhill and the rest of Tennessee while providing a broader alternative to Knoxville.


The initial steps to get the ball rolling for a small change leading to a big change is to recognize right away that U.S. 129 on its current route is not an acceptable route.  The steps of change are as follows:

  1. Reconstruct Runion Road into a new route for TN 68 that will be oriented to allow NC 294 to seamlessly transition into TN 68.
    • This will result in a relocation of TN 68 onto part of TN 123, resulting in the elimination of TN 123 except as a small hidden overlap with U.S. 129
    • Primary movement will be current TN 123 (east) to Runion Road on the south and TN 68 (north) to Runion Road on the north
  2. When this road project (approximately 1 mile long) is completed, relocate U.S. 129 onto this new route according to the previously described routing.
  3. Existing U.S. 129 will become either U.S. 129 Alt or downgraded to state routes depending on what both states decide.
  4. Curve realignment and the construction of truck/passing lanes from Turtletown to Tellico Plains should be conducted where practical to improve safety and speeds along the portion where U.S. 129 and TN 68 are co-signed.
  5. Once this project is completed, begin studies to construct an interstate-grade highway from U.S. 64/74 near Ducktown to U.S. 411 in Madisonville
    • This will be the first phase of a replacement for TN 68 
    • This does not involve U.S. 129 as much as it does TN 68 meaning that it will be a project exclusively in Tennessee
    • It may be constructed as a(n)
      • interstate-grade road (full freeway)
      • surface four lane expressway with ROW for future overpasses/interchanges and additional lanes (bridges should be constructed for six lanes)
      • super 2 (full freeway on a 2-3 lane undivided roadway)
      • surface two lane with interchanges built out for future expansion of remaining roadway
    • All designs should accommodate for an interstate-grade road containing six lanes meaning the super 2 should consist of three lanes with continuosly alternating passing lanes.
  6. When this project is completed, extend an interstate-grade road from U.S. 411 in Madisonville to I-75
    • This should be constructed to full interstate standards following TN 68 and include a high speed interchange with I-75 between Sweetwater and Farragut
    • It should be constructed with six lanes
    • It should be designed in a manner that allows large portions of Old TN 68 to remain on system as a secondary state route to serve the local communities of Coker Creek, Ironsburg, Farner, Turtletown, and Harbuck as well as the cities of Tellico Plains and Ducktown
    • It should include a realignment of Joe Brown Highway to meet the new road
  7. Georgia should begin upgrading existing GA 5/515 between Nelson and Blue Ridge to interstate standards by removing at-grade crossings and constructing interchanges
    • This will require relocation of portions of the highway to new alignment around built-up sections: especially in Ellijay and Blue Ridge
    • Existing ROW may have to be shifted to convert an existing carriageway into frontage roads and to reconnect old alignments into those frontage roads between Ellijay and Blue Ridge such as what currently exists in Cherry Log and Whitepath
    • While this is underway, a study for an interstate-grade road should commence between Blue Ridge and the Tennessee State Line following GA 5
    • The upgrades should include a widening of the existing four lane roadway to six lanes and realignment of substandard grades and curves where possible
  8. Long-term, Tennessee should complete the upgrade of the relocated TN 68 to interstate standards between the Georgia State Line and U.S. 411 in Tellico Plains to full interstate standards.
    • When completed, a six-lane interstate will connect from the end of I-575 in Nelson to I-75 west of Knoxville
    • I-75 will be relocated to this route with existing I-75 reassigned as extensions of I-24 and I-81


What will start out as a simple highway shuffle will over time turn into a long and expensive road project, but it is necessary to create a more direct route between Knoxville and Atlanta while subsequently placing U.S. 129 onto a route more suitable for through traffic.  The major disadvantage of this plan is that it will introduce traffic and development into a scenic and remote area, but this area also suffers from a high level of poverty and very poor access.  It will also cut through mountains destroying the "wild" feel of the area, but this is no different than many projects underway in parts of North Carolina, Virginia, and West Virginia.  The benefit will be is that it will take the focus off of the more pristine areas further east along the existing U.S. 129 allowing it to be conserved for tourism and natural beauty while the less beautiful TN 68 corridor will function as a better route through the mountains than the current route involving U.S. 23, 74 and I-26 from Atlanta that is not designed to handle major interstate traffic and is becoming a worsening choke point through Asheville.  It will also provide substantial economic benefits to East Tennessee that are currently not offered due to a lack of an adequate north-south link.  No other route is suitable.  Any other option is long and dangerous with sharp curves through high mountains.  It is not something that will be completed for many years.  It will likely take as much as 30 years to study and build, so for that reason it is a good idea to start small and start now.

Guide Sign Issues: The GPS Debate and New Strategies To Correct Guide Sign Deficiencies

It seems that a tremendous misunderstanding has happened in what the purpose of guide signs are.  For one, they are not just there as a poor man's GPS.  They are designed to promote a road: to indicate clearly to the public what is the best route to a location regardless of the many options available.  This promotion is not just important for a guidance standpoint.  Cities and towns stand to gain or lose business by their presence on a directional sign, and not having any signage at all can be a safety issue: especially if the only option to a point of interest is a hazardous road with no safe place to turn around.  Finding your way around is a split second decision if you do not know the area.  Thus, the need for these signs has not passed.

Traveling along US 411 in Alabama, a junction with Cherokee CR 29 lacks the first sign you see here.  Once a state route, these two communities along CR 29 have dried up in recent years helped along by the lack of through traffic.  Perhaps if this road were promoted as not only a shortcut to Piedmont, but also these other communities shown here it would better distribute traffic, increase business along the road, and allow a major county highway to serve its intended highway purpose.  However, the sign you see here is considerably large at 7.5' x 3.5' thus a cost that is difficult to factor into a normal budget. 

Guide signs (directions, distance and route signs) have taken a back seat in recent years as federal funding has been made widely available only for warning and regulatory signs while states have viewed guide signs as less important than in the past due to GPS systems that are now easily available.  While they may be partially right, the concept of guide signs is to define routes, not just to show drivers how to get somewhere.  Defining a route means that an expert (engineer or technician) has determined the best way to go based on:

  • Road quality (width, pavement, geometry)
  • Road conditions (speed limits, signals, curves)
    • Some roadways are unsuitable, because they lack a signal in a high traffic area making left turns more hazardous than a longer way
  • Roadway classification (arterial, collector)
    • Most functionally local roads do not reach any cities or towns and do not justify signage
    • Exceptions exist for posting guide signs on a functionally local roads where it involves towns/unincorporated communities, points of interest, or alternate routes when the primary routing it substandard
  • Obstacles (weight limits, height limits, pedestrian traffic, business districts, residential areas)
  • Shortest and best route (not always based on state routes)
  • Roadway designation (guide signs line up with route designation)
  • Combination of roads (single route has overlaps with other major roads or highways) 
    • Note that "route" refers to both numbered and unnumbered routes based on destinations

GPS cannot always determine those conditions.  GPS looks at lines on a map and chooses a way based on distance.  Although items on the list can be programmed in, they are not always indicative of conditions in the field.  Here are some things to remember about GPS before deciding that all the guide signs should just be removed:

  1. GPS is not always correct
  2. GPS has led large trucks down roads with unsuitable conditions including:
    • Substandard bridges that collapsed under the weight of the truck
    • Low overpasses that caused trucks to hit the bridge and get stuck
    • Roads that are too narrow with too sharp of curves for trucks to navigate where trucks got stuck or wrecked
  3. GPS has led cars to roads that were:
    • Unpaved
    • Ended in water such as a boat ramp, ford or canal
    • Came to a dead end when the map showed the road as connecting
    • The road did not actually exist
  4. GPS looks for the shortest route, which is not always the most suitable route.  It leads traffic onto roads that were never designed for through traffic and are not funded at a level to handle high traffic volumes.
  5. GPS is not a substitute for posting information that should be readily available to the roadway users
  6. Most of all, GPS serves as a distraction to drivers who should be focusing on the road itself.
    • Attempting to navigate GPS maps because a necessary directional guide sign or route sign is not available is not acceptable and leads to distracted driving, thus accidents
    • Distracted driving is already a crisis in this country, and it is made worse when drivers are looking at their GPS for directions in hazardous conditions

Virginia clearly posts truck warnings or restrictions ahead of the condition.  Note the "GPS Routing Is Not Advised" plaques that prove that trucks have ignored these conditions before showing the flaws of GPS.

Seeing that this is true, it is NOT a valid argument to call guide signs outmoded because of GPS.  Guide signs are there to define routes according to the list above.  That means either highways or the BEST route to a city/town, nearest highway, park, historical site or public facility.  This includes not just state highways, but also local roads since all these factors regarding local roads are true:
  1. Local roads may actually be highways that are simply not maintained by the state
    • Nationally, most states maintain primarily roadways that are considered arterial routes of statewide importance
    • Collectors and many urban arterials are increasingly becoming the sole responsibility of local governments who are not structured in a way to manage higher classification roadways
    • This means many local roadways may actually carry highway traffic over long distances even though they are not the responsibility of the state DOT
  2. Landmarks, parks, recreation areas and other points of interest are often not located on the state highway system
    • Parks and facilities off-system often require many additional turns to reach.  These turns are not always signed, especially when the turn that is required is along a local road.
  3. Cities and towns are often located at a point just off of a state route or are not situated along a state route.  This is increasingly true as states continue to reduce their mileage.
    • Cities and towns are often found on old highway alignments and along major county roads in some cases as much as 10 miles from the nearest state highway
    • The trend of cities and towns removing highways through their core has resulted in poor guide signage through the cities as both states and counties rely on the municipality to define truck routes and destinations beyond the city and town itself
  4. The shortest and best route may actually be along a local road as opposed to a state road.  
    • The location of state routes is often politically motivated and may follow convoluted routes where a shorter, faster, and better constructed road may actually be locally-owned
    • Nonetheless, the state will typically avoid guiding traffic onto a local road due to the following reasons:
      • A lack of guide signs at a junction of two local roads where a turn is required to reach a destination
      • A lack of guide signs where a local highway approaches a state route.
      • Because the roadway itself is not maintained to suitable standards (inadequate traffic control or pavement markings)
      • Because the roadway has design characteristics not suitable to through traffic (this is the only justifiable reason).
  5. Local highways may go long distances before connecting to another state highway.  This is common in many western states where state control ratios are often less than 10% and distances between developed areas are further.

Here is an example of a state highway that does not provide the shortest nor best route.  While it is potentially a turnback candidate, the issue is that it is signed for Morganton from US 19/129 (and Blue Ridge sporadically).  Google clearly shows Loving Road as the shortest and best route.  Taking SR 325 is eight miles out of the way and taking the more convoluted northern route is 6 miles out of the way.  If guide signs were posted at two intersections on Loving Road at US 76/SR 515 and SR 325, it would provide the shortest and best route.  It has no truck prohibition, is eligible for federal-aid, and it serves as an example of why guide signs should be related to roadway function instead of jurisdiction.

Cane Creek Road in Pickett County, TN is an example of a highway under local control.  It becomes a state highway in Kentucky.  The sign on the right indicated the roadway's former federal-aid secondary number before TN eliminated federal-aid funding from rural county roads.


The simple answer discussed in a prior post is that the state just takes over the responsibility of guide signs for local governments, but this has not been happening.  That involves the state assuming responsibility for posting and maintaining guide signs on all public roads regardless of ownership as a means of synchronizing state and local roadways so that guide signs are based on function and need instead of ownership.  That sounds good, but there are a number of problems with that:
  1. Not all states are doing a good job with their own guide sign program
    • Georgia, Kentucky, Massachusetts, Rhode Island and Maine are examples of this: states that lack any specific specialization and have numerous deficient standards, missing signs and errors
  2. County routes, if they exist, are not based on a logical farm-to-market system because local home rule is used to define these roads in lieu of a centralized approach.
    • In these cases, the state was unwilling or unable to continue managing a farm-to-market program turning that responsibility over to the local governments leading to numerous inconsistencies (typical of county routes in Alabama, Oregon, and Colorado)
    • The state cannot realistically manage or be liable for a system with such a high level of inconsistencies, because it would show preference for participating vs. non-participating counties
    • Some counties oversign county routes while others do not sign enough routes (meaning every single county road is marked with a blue pentagon)
    • Others revoke the program entirely (in some cases the county routes exist on paper but not in the field)
    • Routes are inexplicably renumbered, change numbers, or disappear at county lines (CR 25 in one county becomes CR 1480 in the next, or CR 25 becomes a named road across a county line)
    • Routes are defined by ownership instead of function meaning that they are not signed upon entering city/town limits even though cities and towns in most states are part of a county (CR 65 becomes an unnumbered route upon entering a city even if the junction with the nearest state highway is only a mile away)
  3. States refuse to accept the liability of posting signs on roads that they do not own
    • In some cases home rule laws that were not well thought out are the blame, but in others the state simply wants no part in directly managing local affairs
    • Lack of communication means that problems that present a hazard to motorists are never addressed and that signage is inconsistent
    • Extremely incorrect or outdated information is often left on any remaining signs since most guide signs were installed by the state decades ago, and they are generally replaced "in kind" instead of reviewed for accuracy of information.
  4. States refuse to incur the additional expense and responsibility of installing and locating signs on roads that they are less familiar with.
    • Even if states do not manage any other function, it would be a minimal cost for the state to assist in guide sign installation and management, at least in rural areas
    • Since roadway classifications do not line up neatly with state control, this means that the system would function much more smoothly if they provided this service at no cost to local governments
  5. The decline in state funding and control in many states means that the economies of scale on a state level are poor.
    • This means fewer internal resources to manage guide sign planning and maintenance.
    • Because the state has to cut services, reduce staff, and outsource guide sign work to prisoners or contractors, the available oversight is not there to make sure that signs are designed correctly and placed in the field in a proper or consistent manner
    • As-is replacements are used instead of periodic review
    • Knock downs are neither located nor replaced
    • Sign clutter becomes a problem, because signs are added instead of grouped and planned properly
  6. States may indeed install guide signs on local roads, but then they would expect the local government to maintain these signs when the majority of local agencies lack the equipment or resources to effectively maintain these signs.
    • Very few local governments install directional and distance guide signs, trailblazers or any other route sign other than county routes (this is viewed an excessive expense)
    • Guide signs on former highways left over by the state are never replaced, updated or are simply removed
    • Other guide signs installed by local governments are inconsistent from county to county and typically do not comply with either state or federal standards.
    • Guide signs on a local level are typically not designed by people with any level of technical expertise to make sure that they are appropriate or correct
    • Guide signs are often the most expensive signs to produce requiring a higher level of technical expertise and materials not typically required for warning and regulatory signs such as unusual hardware, framing straps, z-bars, larger signposts, design challenges, and space is often limited on where to put the signs.
    • Signposts often must be of different lengths when terrain is uneven
  7. Some "guide signs" are actually special warning or regulatory signs.  These are special signs with similar design characteristics such as roadway prohibitions (e.g. "Notice: Candler Mountain Road Closed in Winter", "Trucks Prohibited on Maple St"), or W16-8a signs (longer street names can make these signs very large).
    • Local agencies often produce these signs too small to avoid the difficulties of producing and installing a larger, more legible sign

Guide signs are expensive and have more complicated planning than other signs.  This is the result of what happens when standards are not adequate.  In this instance, one sign for the state park would have sufficed, and the design of the green sign is sloppy and non-standard.  While this has most likely been removed, it demonstrates the need for a heavily centralized, specialized, and engineer-driven approach.

In this instance in Hughson, CA on CR J7, you see how wrong a guide sign can go even when one is properly planned but designed improperly.  This sign does not meet either MUTCD or CalTrans specifications for design even though the basic information is presented correctly.

In other words, blindly relying on the state alone more often than not means little to nothing is ever done.  A federal infusion is needed to highlight the problems and demonstrate the importance of this issue.  States DOT's should also make this a specific program to local governments usually with a PTOE hired to specifically manage the program and a process established to do so.  A local guide sign program should be coupled with state-owned guide signs so that the entire guide sign program is managed consistently on both levels of roads and projects should be grouped on both state and local roads to better manage material costs and coordinate signage.  Local agencies often do not recognize the problem, and state governments are not always structured in a way to mediate the problem.  Even when funding levels are adequate, it does not mean that either the state or local government has ever seriously considered the issue.  


Across the country, only about 1/5 of the states have a road system that is centralized enough to adequately manage guide signs.  West Virginia, Iowa, Wisconsin, and Delaware appear to have the best program with high standards, frequent maintenance and consistent application both on highways and local roads.  The problem in West Virginia and Delaware is that both have the vast majority of their roads under state control: not typical in most of the country.  Iowa and Wisconsin are the notable exceptions, and it is related to a strong culture of local traffic engineering standards lacking in other states, but it is out of the ordinary.  Wisconsin also has an overlaying road system where the counties are contracted to maintain state routes resulting in greater state oversight of county activities.  Obviously centralization has a major advantage in regards of planning and maintenance of guide signs compared to states who do not.  States that transfer roads to the local government, on the other hand, have difficulty managing guide signs, especially when route signs change in a way that destinations become invalid over long distances.  When information is not reviewed and updated when routes change, the public learns that they cannot trust these signs to provide useful information.

The three strategies needed to fix this are:
  1. The creation of a federal guide sign program
  2. Specialization (including specific state programs)
  3. Privatization
The Federal Guide Sign Program (GuideWays)

First, it should be considered that few things have helped local governments more than the state application of the High Risk Rural Roads Program on a local level.  For decades, the concept of a traffic study or installation of safety improvements by anything but the local government on local roads was unheard of.  If the county or municipality could not afford to do it on their own, it just was not done.  More often than not, local priorities went to constructing new roads, replacing bridges and repaving roads leaving next to nothing for traffic control.  Once the stop signs were installed, speed limit signs put in place and street name signs put in there was nothing else left over.  Certainly that did not include money for traffic studies or replacing the faded out traffic striping.  While these conditions still exist, they are less frequent than they once were.

What is vs. what should be.  The actual image from Google Maps above shows a tornado-damaged guide sign that was already decades old not being maintained a the junction of US 278 and CR 19, a major county route connecting Centre and Jacksonville, AL.  Jacksonville isn't even mentioned on that sign, and most likely the guide sign dates to the 1970's as a means that the state used to provide additional guidance across county lines from where they actually maintained the road.  If properly planned today, this is what you would see at this intersection.  With no program or funding in place, fixes like this just do not happen anymore.

Even now, guide signs are still non-existent on local roadways, and that is because it never was good in the first place, and no funding is available on a state level for this work.  A new federal guide sign program could eliminate this problem.  The guide sign program takes the existing HRRRP effort and expands it to include a pool of resources just for guide signs.  However, unlike the High Risk Rural Roads program where specific roads are selected for renovation and money is never enough to address every deficient road in a county or municipality, this program would be different.  It would select a county (including all cities within) for a total renovation of guide signs.  These would include signs on state roads, county roads and streets in municipalities all within the same county.  How it would work is that:
  1. The state selects an engineering firm to study every road in the county.  The firm will review the following:
    • Needed guide signs on local roads including trailblazers, directional signs, distance signs
      • "TO" route assemblies are considered trailblazers
    • Boundary and waterway signs
      • This includes city limits, town limits, unincorporated communities/CDP boundaries, county boundaries and state boundaries
      • This includes crossings of lakes, rivers and streams
      • Unincorporated communities are just as important as cities and towns since many unincorporated communities form junctions of highways as well as destinations for many roadways.
    • Junction route assemblies and county route markers (if used) on local roads
      • This includes posting route and directional assemblies on major local roads approaching the junction of a state highway
      • This includes correcting and improving the information on county routes including adding directional banners, junction assemblies, cardinal directions and reassurance signs
    • Where recreational, informational and other guide signs of public interest are needed
      • This includes guidance to state parks, colleges, hospitals, government facilities, stream crossings, jurisdictional boundaries, unincorporated communities, recreation areas and other points of interest
    • Study guide signs on state roads to see if the information is up-to-date and correct
      • Guide signs may reflect destinations and distances on older routings that are no longer valid
      • Guide signs may direct traffic to destinations along county roads previously on the state highway system where guide signs may have been removed along that former highway
    • Integrate or correct guide signs where a conflict exists with state and local roads
      • If a county road or municipal street is adequately constructed as such and it is of adequate functional classification, it may be the preferable route to the more convoluted state route
      • Inquiry from local officials should be obtained if it is acceptable to post the shorter route, and if so should truck restrictions be posted
      • Review signs outside the county boundary that conflict with signs within the county.
      • Include signs in conflict outside of the county as part of the study and notify appropriate public officials of the problem
    • Determine if guide sign text and dimensions on state-owned and locally roads comply with the MUTCD and if the signs need to be larger with larger text
      • An example is using 6" text on an expressway-type road (such as an APD corridor) instead of the required 8" text
      • Substandard guide signs on surface state roads would also be corrected to better comply with the MUTCD in dimensions, fonts and design
    • Identify which signs need replacement, where corrective action is needed or where new signs need to be installed
      • This is all indicated in the traffic study, which identifies these issues in a single plan
    • Add, replace or correct other related warning signs around the study area that involve the intersection including the installation or replacement of the following:
      • W2-x signs, W3-x signs, or W1-10x signs coupled with W16-8/W16-8a signs where a roadway with guide signs lacks a posted route number
      • W1-7 signs at T-intersections (including any state-specific design for object markers posted with W1-7 signs)
      • Any other current or needed warning signs within the study area if the signs need to be replaced or installed; this is important, because guide signs need to be coordinated with all existing signs to facilitate proper spacing
  2. Once the study has been completed, the firm will file for a federal reimbursement along with a federal grant needed to cover the cost of installation of the new signs including correction of signs in conflict outside of county boundaries
    • The federal government will have already pre-approved the study
    • Funding will be needs-based, but may not exceed a budgeted amount
  3. The state will hire a contractor to produce the signs and another to install the signs within the bounds of the project area.
    • When completed, ownership of the signs will transfer to the legally-permitted agency

In order for a guide sign program to be effective, this cannot be simply grouped in with other state or local matters.  A specific unit of state government must be in place whose only duty is to plan and design guide signs.  It may even be completely removed from the state DOT, and it could be part of a statewide roads unit.  The Statewide Contracting Plan details this, but essentially local government matters should have a central agency that they can use to provide specific, consolidated services that the state DOT does not want any part of.

The unit should: 
  1. Develop specific uniform standards (these should be included in standard drawings and in a state MUTCD supplement)
    • Framing strap/z-bar details
    • Route assembly details
    • Detailed designs of state-specific signs such as jurisdictional signage and route signs
    • A standard procedure for posting guide signs on both numbered and unnumbered routes
  2. Create templates for commonly used guide signs
  3. Make each sign according to state/federal specifications with an inspector available to reject errors
  4. Have their own shop where the signs are created in-house instead of assigned to contractors or state prison workers.
  5. Be managed by or staffed only by professional engineers with a PTOE certification and technicians with specific training who work for the PTOE  
All guide sign workers should be specially trained in state and federal standards, and they should not be assigned to any other duty to make sure that their sole focus is on guide signs.  However, they may assist in designing and producing any text-based custom sign such as the W16-8 advance street name sign.  Although the W16-8 sign is a warning sign, it functions like a guide sign.  In addition, local governments should be able to contract with this guide sign unit thus able to purchase signs or request supervision of their local guide sign program at the expense of the local government involved.

While most warning and regulatory signs may be purchased from contractors, guide signs require a higher level of technical expertise that means that they should always be produced in-house by employees who have the knowledge, interest and expertise to do the best job.  

Another option is regionalization for this purpose.  If a regional highway system is developed with resources comparable to state levels, the region can provide this service on their own with the state government contracted with the regional road system for installation and maintenance of guide signs as well as other traffic signs.


If a state lacks the resources or interest in handling guide sign matters directly, the state should contract this responsibility to one or more private engineering firms who handle this on a day-to-day basis.  If this is privatized, the state government should encourage local governments to latch on to the program by paying into it.  The state will incur all engineering costs, so local governments will receive guide sign planning and maintenance from the private firm according to what they pay in with planning handled by the firm and installation/maintenance furnished by a subcontractor hired by the firm itself.  With a private approach, it will hopefully assure that professional standards will always be met and that changes can be made incrementally in the absence of a federal-aid program.  While many local governments may not participate, the shared costs will mean that overall costs for guide sign installation on local roads will be lower than if the county/municipality handles it on their own.    


The previous post on this issue included a list of what the state alone should handle for local governments, but if the local governments were actively participating, they should also have the option to include the fabrication of street name signs (at their own expense).  Both state and local agencies should be able to rely on this unit for the fabrication of:
  1. All text-based guide signs (D1-x, D2-x, D3-x), including large freeway guide signs
  2. Special text-based signs (custom signs not found in the MUTCD)
  3. W16-8 advance street name signs (custom warning sign)
  4. Interstate, U.S., State, and County route markers (M1-1 through M1-6) and banners (M2-x through M6-x)
  5. Specific guide sign traffic studies

Guide signs as a whole need a very integrated strategy to be useful and effective.  Information on guide signs should be consistent based on route designation, road function and directional changes from endpoint to endpoint.  If a guide sign points you to Woodville yet additional turns are required to reach Woodville that are unsigned, it is a serious problem.  Not only will you not reach Woodville, but you may end up on an unsuitable road where you run out of gas or get a flat tire.  It is not acceptable for Woodville to not appear on any sign if additional turns are required at subsequent road junctions.  It means that it has misled drivers, is not effective, and poses a liability.  This means that taking a decentralized approach is a bad idea.  

In fact, the whole process of managing guide signs should be as centralized as possible: in fact more so than any other roadway function.  While it is possible to handle regulatory and warning signs effectively on a local level, this is not the case with guide signs.  Instead of being just one duty of the state's traffic control division or local highway department, guide signs should be their own separate statewide unit that handles this responsibility exclusively.  In order to do this, as many parties need to be involved as possible since this is not as everyday of an activity as putting up a stop sign.  Standards should be clearly written, local governments should be covered in the plan (and preferably helping to fund the unit) and guide sign workers should be specifically trained to handle this matter.  The more centralized this is, the lower the material costs will be allowing for better maintenance and higher standards.

In addition, a far more engineer-centered strategy is needed.  This means that a major study should be conducted on the ENTIRE road system in every county in every state: not just on the state roads or local roads.  This should be federally-funded as well with specific grants for that purpose.  Handled on a county level covering all levels of ownership from the state level to the town level, problems can be identified in a wide scope without worrying about smaller jurisdictions.

Shoddy Signs Spotlight: Rabun County, GA

The funny thing about non-compliance issues with traffic signs is that it is a problem that is hiding in plain sight.  Somehow, a serious safety issue just does not get the attention it deserves: perhaps because not enough people are paying attention or the problem is hidden because it looks professional.  In these cases with local agency issues, the signs themselves may be MUTCD compliant, but the engineering work is sloppy or non-existent and application sporadic.  In other cases, the engineering may be correct but the traffic signs are non-compliant with numerous issues with sign condition, fonts, post height and symbol design.  Usually, shoddy traffic engineering goes together with shoddy signage and pavement markings, suggesting a disinvestment by that agency in traffic safety and traffic control.  While most common in rural areas, it is as much of an urban problem as it is a rural problem especially in smaller municipalities carved out of larger urban counties.

While not the most egregious example, the design of these signs presents a problem to drivers approaching the intersection in a curve.  It implies that either way is through traffic instead of the curve to the left despite the fact the left arrow is larger.  The advisory sign is also not properly designed although not as bad as some other examples around the county.  Sign is located on Old U.S. 441 north of Lake Rabun Road south of Lakemont.

Sometimes, however, there are local agencies who go out on a limb and handle their assigned duty so incorrectly that photos do them plenty of justice.  We posted a golden example of this with the disgraceful practices of Cullman, AL showcased.  These are agencies that clearly have neither guidance nor will to follow proper roadway practices, and they get away with it largely because of the laissez-faire attitudes of state governments who will not penalize non-compliance possibly due to the fact that they are not even managing their own work well.  Legally their hands are also tied because of home rule laws preventing any significant interference thus there is no such thing as checks and balances in traffic engineering.  GDOT is certainly a state with its own issues with managing traffic control, so it is no surprise that Rabun County, GA was one of the latest counties to abuse their authority to maintain traffic control devices.

Prior to the late 2000's, speed limit signs were standard design.  Then this happened.  Sign is located on Old U.S. 441 southbound.

Rabun County is a mountainous county with just under 17,000 residents.  It is well known as a quasi-rural county that is also a popular weekend home destination for wealthy residents in places like Atlanta, Charlotte and parts of Florida and is also a popular retirement destination.  Because of this, the county has far more houses than it has permanent residents.  Located along the Blue Ridge Plateau, the county has some of the most stunning scenery in the state with many impressive waterfalls, beautiful forests, and a rugged landscape that is more typical of Western North Carolina or New England than the Georgia Piedmont attracting large volumes of non-local traffic during sunny weekends, summer months and holidays.  It is also a county with many dangerous roads due to abundant steep grades, sharp curves and dangerous intersections.  For this reason, the abject failure of either the state or the county to provide high quality, properly engineered traffic signs is a travesty.  The recent efforts by the county show a very half-hearted effort that calls for immediate correction.  Like most counties in Georgia, it also appears that there has never been a proper traffic study on all but a couple of these roads under local control.

If any sign highlights the inexperienced employees at Rabun County's road department, it is this sign.  This confusing mess of a sign is easily demonstrated with two MUTCD signs: a Hill (W11-7) sign and a Right Turn (W1-1R) with a 30 MPH advisory speed.  A truck advisory posted here is already too late if this condition is this hazardous!  If trucks need to be aware, it is at the beginning of the road.  The diagram above better explains this.  This wordy sign might look important, but it is dangerously non-compliant, crams a ton of information into a single sign and should be removed as quickly as possible.  If the curve really is that hazardous, the best thing they could do is install chevrons in the curve ahead with flashing lights to warn drivers if they are approaching too quickly.  These situations do not happen when traffic control is handled by qualified employees under adequate supervision and funding levels are adequate.  Apologies for the antenna in the left side of the photo.

Here is the curve described in the sign above.  While it is indeed mountainous in the location, the hazard appears to be overstated.  This is where a proper traffic study of this road would have been very useful, but the state's program to correct issues on roads like this did not have sufficient funding to correct problems like that.

Rabun County is not quite as bad as the Cullman example in that there were at least some efforts to follow standard practices.  The county uses approved fonts, for instance, though the application of those fonts is usually incorrect.  The county also partnered recently with GDOT to have four county roads re-engineered for proper signage with federal-funded replacements meaning that those roads are momentarily no longer presenting an issue until further maintenance is needed.  It also does not mean that the problems that do exist are not just as glaring and extreme on every other road.   

The sign shown here was one of the signs on Bridge Creek Road with a completely unacceptable advisory speed.  The condition was corrected when GDOT partnered with a private firm to re-engineer the warning signs on this road, but this was one of only four roads to receive this work.  Other county roads still contain massive errors like this.

The solution for this problem is not so simple.  Even if these comically bad signs are all corrected, the traffic engineering work is sloppy at best.  It is unfortunately typical that signs in mountainous areas are very inconsistent due to the lack of any consistent policy nationwide for curve warning, chevron and arrow signs.  To make matters worse, those roads that Rabun County contracted to GDOT for help on used the same engineering practices they used in the Piedmont meaning they were extremely oversigned: an issue that will also worsen the issues with maintenance.  This oversigning is partly due to GDOT lacking any internal policy where curve warning signs in mountainous terrain may only be posted when a speed reduction is required.  In fact, those four roads that were re-engineered have far more signs than the county has resources to maintain them.  For example, in a series of S-curves on Warwoman Road, nearly continuous chevrons were posted in lieu of just lowering the speed limit along that stretch so that they would not be required.

Neon non-compliance.  A "SLOW" sign, long removed from the MUTCD, is placed in neon colors (pedestrian?) with a Blind Drive sign.  This was also on Bridge Creek Road, so it has likely been corrected but may exist in a similar condition elsewhere in the county.

Design fail here on Black Rock Mountain Road, the county-maintained spur to Black Rock Mountain State Park.  Neither the advisory nor curve sign are correctly designed on a post about 2' off the ground.

GDOT's lack of direct funding or oversight of local traffic control work also poses a problem.  In all, Rabun County's terrain mainly calls for engineering corrections only on these longer and more heavily traveled mountain roads where other less important roads with continuous hairpin curves can be corrected by either setting the speed limit to match the determined advisory speed for a majority of curves or in the case of residential roads not posting these signs at all.


Another issue are the county's guide signs.  Many important attractions and small towns are found off the state highway system especially in the southwestern part of the county, so posting guide signs for the purpose of tourism is of heightened importance.  The state marks these attractions only along US 441 south of Clayton, but does not usually mark them elsewhere.  However, the county enacted their own guide sign program within the last 10-15 years posting guide signs at major intersections throughout the county.  The problem is that these were poorly planned and designed guide signs that clearly were not authorized by a traffic engineer, are poorly laid out and do not reflect the shortest and best routes.  While their heart was in the right place, this is something that the state should have provided assistance with and/or a PTOE should have planned or reviewed.  All of these guide signs should have been coordinated with state roads, and if these roads had proper warning signs, regulatory signs and truck restrictions posted on the most mountainous roads (such as Lake Rabun Road), the state could have even routed through traffic along some of these roads as the shortest and best route.  For example, traffic coming from Helen along GA 197 could use a combination of Burton Dam Road, Bridge Creek Road and Old US Hwy 441 as a shorter and less winding route to reach Tiger and Clayton, but currently traffic is routed along the windier and longer GA 197 and US 76 simply because the better route is under local jurisdiction.

Signage on Germany Road at Black Rock Mountain Road has the correct colors and fonts, but it has poor design with arrows in the wrong place, too small to see and an improper application of destinations.  "Mtn City" does not need "GA" (it is in the same state), Black Rock Mtn should have "State Park" spelled out and on a brown sign and the directional "N" is not needed with US 441.  The borders are also incorrect.

Another guide sign posted on Blue Ridge Gap Road at Wolffork Road further demonstrates the issues with these signs.  The layout is completely wrong.  The image below shows how the sign should preferably appear.

While 6" text would be ideal on this sign above (4" is used like the original sign), the design is far closer to MUTCD standards than the sign in the image above.  In addition, a major destination is added for northbound traffic that is missing from the current sign considering that prevailing traffic is going northbound on US 441.

Counties like Rabun County are important, because they dispel the myth that local roads do not need the same effort as the state because local traffic "knows the roads".  The problem is that this area frequently has lots of traffic from people who are not from the area who are exploring the back roads looking for the many lakes, waterfalls, recreation areas, property for sale and/or visiting historic areas such as Lakemont.  This means that both the state and the county have a responsibility to provide a consistent driving experience both on the state highway system and off the state highway system.  Considering that the county overall does an acceptable job in other areas of road maintenance with smooth, reasonably well-built roads, the solution clearly will require a cooperative effort with resources outside of the county.  


While the local government can theoretically fix the problem on its own, the reality is that Rabun County is a low population county.  Because of this, any local effort would take an excessive chunk of the budget with not enough trained employees to assure that it is being handled correctly and a very large tab for engineering studies and consultants.  One potential solution that could be pursued is hiring an IMSA-certified traffic control technician sponsored by a PE, but that PE would likely operate outside the county thus still requiring a regional effort.  That is by no means a guaranteed solution, but it would help with the most glaring issues.

For this reason, it would be best for the county if they would consider becoming one of the pioneers in pursuing a regional traffic control plan.  The first step the county could take is to partner with a neighboring county by merging their traffic control units.  It just so happens that Rabun County borders Habersham County, a county with a traffic engineer who appears to be especially knowledgeable about traffic control and has invested heavily in the county's signs.  Rabun County could agree to share the cost of funding the county engineer based on proportion of population to the population of both counties combined (meaning Rabun County would cover 27% of the cost).  The cost savings for Habersham could be used for Habersham to help fund initial traffic studies for Rabun with the difference or to furnish them with traffic control devices.  This would cost far less than the county attempting to figure this out on their own.  Consider how this would work if the two counties combined costs:

  • Habersham County has a population of 43,752 (2014)
  • Rabun County has a population of 16,243 (2014)
  • The combined populations of both counties is 59,995
  • Thus Rabun County's population ratio divided by the combined population is 27%

Under this combined effort, Rabun County could then provide a budget for the county engineer to work with allowing him the authority to oversee county traffic control, combine purchases, use a single sign shop for both counties and share costs.  It would be a win-win for both counties.  Habersham County saves money on a traffic engineer in turn for Rabun County receiving better supervision for a critical county service.  If the county engineer's salary is, for example, $85,000 a year then Rabun County contributes $22,950 in turn for Habersham providing an equivalent sum in traffic studies, traffic signs and pavement markings.

More proof that these are not isolated incidences of weird, shabby signs.  The 35 MPH advisory is at least correctly sized on the second sign, but the "ADVISORY" information is redundant.  Perhaps a pedestrian crossing sign might be more appropriate as this second sign is entering the village of Lakemont.

Corrected since this photo, but also redundant (Bridge Creek Road)


The combination of the two county's traffic control units and engineering units should not be where it stops. While the combination will result in better roads and huge cost savings for both counties, no special reason exists that it has to end with two counties.  If the fusion of two counties for roads is successful, then the two agencies should then try to recruit other counties in the Georgia Mountains Regional Commission boundaries to join them starting with counties that are bordered by both counties.  This means first Towns and Stephens Counties.  Like Rabun, neither county has a traffic engineer hired and neither have the resources to provide adequate traffic control services on their own.  Before this is done, however, both Rabun and Habersham should turn to the cities within to also combine traffic control with the counties.  If those counties and cities agree to join then they can attempt to recruit more adjoining counties and cities within such as White, Banks, Franklin and even Hall County.

Beautiful scenery surrounds this atrocious assembly with the completely unnecessary "CAUTION" plaque (a W16-8 street name would be better), improperly sized W2-1 and advisory speed on an incorrectly sized 24" x 18" blank. 

The idea here is that because most of the counties are incapable of adequately providing these specific public services to proper levels on their own, they begin to form a regional highway system starting with traffic control.  Obviously, organic growth of a regional highway system is a fertile ground to test regional transportation solutions.  It is not a permanent solution, but it is necessary to prove to state leaders that combining specific roadway functions without transferring ownership to a larger agency could be successful.  If no counties are willing to pioneer the concept, then the state is also not likely to pursue it.

Limited Sight Distance was removed from the MUTCD in 1988, but the design is what makes this worse.  It is hard to read from any distance and is proportioned strangely.

Let us consider that Rabun County is now formed into what is now known as the (entirely fictional) Tallulah Falls Local Roads Cooperative.  The Tallulah Falls Local Roads Cooperative is now an agency spanning seven counties.  We will assume in this instance that Hall County declined.  The new cooperative has the following duties:

  • Traffic Engineering
    • Each partner county pays a percentage of the salaries of all staff engineers based on the ratio of the county population divided by the population of all member counties combined
    • In turn, each partner county receives engineering services or safety improvements based on need
      • Note that the Rabun-Habersham exchange model will not work with more than two partners
      • Services rendered will be considered free based on the operations costs, but costs for materials must be funded by each member jurisdiction
    • Additional traffic engineers or technicians hired must be agreed upon by all parties
  • Traffic Control
    • All purchases are combined for all traffic sign materials, pavement markings and guardrails
    • A central sign shop is developed for in-house materials
      • This is needed primarily for the production of custom signs including street name signs, guide signs and special warning/regulatory signs
      • Not all traffic control devices will be produced in-house
    • The centralized traffic engineering unit supervises all installation and maintenance of traffic control devices
    • Each member agency receives in traffic control what they put into it.  
      • This means that if Rabun County budgets a retainer $10,000 in a single year for traffic signs and pavement markings, the central traffic control unit will be permitted to spend that much in Rabun County
      • Anything not spent in that year will be rolled over into next year's budget for that agency
  • Leadership
    • A committee is formed out of existing elected leaders (one from each county and city participating) that oversees the activities and budget of the local roads cooperative
    • The committee supervises engineers and other employees in the cooperative making the final decisions on hiring, firing, policies and standards
    • The committee meets jointly per request of committee members

As to the combined population and ratios for the Tallulah Falls Local Roads Cooperative, here is how it breaks down:

  1. Seven counties (including cities) with a combined population of 165,102
    • The combined counties have changed the population characteristics for road funding from a series of rural counties to that of a small urban county such as adjacent Hall County
    • This means that the resources could then be distributed like a more urbanized county
  2. Very low payment ratios required of each county since they have similar population characteristics
    • Habersham, the highest in population, would be required to pay 26.5% of the cost for a traffic engineering unit vs. 100% of the cost now for their own county
    • Towns, the lowest in population, would be required to pay 6.7% of the cost for a traffic engineering unit for which they currently have none
    • If three engineers were hired at $100,000 a piece, the cost for Habersham would be likely less than the cost for one full-time engineer while for Towns County would be $20,100.  For Towns County, this is the equivalent to one full-time employee earning $9.66/hour.  

So we can assume now that the Tallulah Falls Local Roads Cooperative is a roaring success.  Everyone is happy with the results, and road maintenance in the boundaries of the cooperative is noticeably better than before and is also better than surrounding counties.  To many, this would be a place to stop but informal committees like this have a way of falling apart.  While it may be sunshine today, a dispute between two county commissioners could unravel the entire structure tomorrow.  This is why this strategy should be considered a pilot project lasting no more than five years.  If the cooperative plan is successful, the next step should be to put it in state law letting the legislature further define the duties, responsibility, funding and organization of a local cooperative.  Having the state involved also opens the opportunity for state funding for each unit.

Another badly designed sign on Black Mountain State Park Road.


At this point, the state legislature has taken notice of the Tallulah Falls Local Roads Cooperative and is impressed at how successful it works vs. the separate county road systems.  The state then takes one of two tactics: expands the concept statewide transforming the regional cooperative into a statewide cooperative or it creates other regions around the state including an expanded and reconfigured Tallulah Falls Local Roads Cooperative.  With the state mandating that each county becomes part of a cooperative, it suddenly becomes even cheaper and easier for the cooperative to afford high quality road maintenance.  The newly drawn region, however, changes in characteristics with Franklin departing for a new region while three new counties are tacked onto the existing cooperative.  In all, this fantasy scenario points out that that when a county does not have what it needs that combining operations with adjacent counties is a cost-effective way to eliminate that problem.


In this scenario that was presented, what is clear is that the county is not doing their job correctly and that existing leadership being made aware of the problem is neither a guarantee that anything will be done about it nor is it an effective way to fix the problem.  While the issues are worse today, they only became obvious because a poorly funded, poorly trained and poorly staffed county agency attempted a greater effort than in the past without the management, training or experience necessary to do it the right way.  It was not exactly better before.  The difference in the past was that the county simply lacked traffic control on almost any roads.  Even if everything existing today was replaced in kind with the right materials, it would still be wrong because the engineering problems would not be fixed.  It is simply not an area that is their expertise, and the situation was worse because they did the work themselves without the knowledge on how to properly design traffic control devices rather than just purchase materials from a proper vendor.  They certainly saved money by doing it themselves, but the resulting signs were disastrously non-compliant.

For this reason, the only economical solution is to stop trying to do it themselves.  Because of the small population of the county, the county's options to fix traffic control issues is twofold:
  • Transfer the responsibility to GDOT (not currently offered to any county or city)
  • Combine resources with one or more counties so that trained staff and adequate resources are available to do what Rabun County cannot seem to handle (starting with Habersham County)
Hiring a private engineering firm may also be a consideration, but the costs involved would probably be excessive for meeting those goals.  The use of private firms for public roads should be something brokered by the state on behalf of the counties, and this is explained in the Private Option of the Statewide Cooperative Plan.

Creating regional traffic control solutions need to become common discussion around Georgia as a means to assure that public safety is treated as something of high importance.  With such a high number of counties, relying on county government is not an effective solution to this problem as this post demonstrates.  Exposure of the problem may lead to some small changes, but they would not be enough to correct the overall situation.  The overall situation is a lack of coordination among properly trained employees, and a lack of economies of scale needed to make sure the most can be done with the least resources.  The better solution is to stop looking within for the answers when it involves rural counties such as Rabun and to start looking at ways of handing this responsibility to qualified professionals.
