Weather and Road Condition Information in Georgia

In This Article:

Safe travel in winter can be difficult in the mountains of Union County, Georgia. U.S. Route 19/Georgia 11 serves as an important corridor, connecting the county seat of Blairsville and other parts of the county through Neels Gap to health facilities and other amenities in nearby Gainesville, Georgia, in Hall County or further south to Atlanta.[i] A scenic route where the Appalachian Trail crosses the road, this route is particularly important for public safety, ambulance calls, and anyone needing to access the hospital in Gainesville.[ii] A partnership to connect broadband to state- and county-owned ITS assets, including cameras and a road weather information system, is improving access to information about travel conditions for residents and others traveling through the county.

Project Purposes

Union County owns two traffic cameras at Neels Gap that were installed around 2016, and the Georgia Department of Transportation (GDOT) has an additional traffic camera and weather system on-site that records air temperature, roadway temperature, the dew point, and other data.[iii] However, this infrastructure was only connected to county and state systems by a cell phone internet connection, which was unreliable in storms or even when the mountain was surrounded by thick, low clouds. The internet connection was so slow that the cameras could only transmit one frame with a vehicle passing through the area, which did not provide any information about how vehicles were traveling. Without reliable technology, the county government’s chief executive and Sole Commissioner became the travel information system himself, driving to the top of the mountain in poor weather, even in the middle of the night, and posting updates on Facebook to let the public know about conditions.[iv]

In 2019, Union County worked with Blue Ridge Mountain Electric Membership Corporation (EMC), the region’s rural electric cooperative, to bring broadband to Neels Gap to connect the ITS assets there and provide a connection to the outdoor sporting store Mountain Crossings, which serves Appalachian Trail hikers and others.[v] Traditional methods for laying fiber would have been cost prohibitive in the mountainous area and would be difficult to navigate from a permitting perspective, going through the Chattahoochee National Forest. However, Blue Ridge Mountain EMC worked with Southern Company Services to fly a drone between ridge tops to place a pull line that would take fiber up the mountain, as shown in the image on page 8. With this process, Blue Ridge Mountain EMC obtained a permit from GDOT to run the cable at the proper height over a state-owned roadway and a permit to run the cable over trees in the national forest. Typically, a project to run fiber along the power lines would require extensive tree cutting under the line to allow access. This would necessitate a much more extensive permitting process in which EMC staff identify the trees to be removed, following which Forest Service staff measure the board feet of those trees. By avoiding impacts to the trees, the paperwork was much quicker for Blue Ridge Mountain EMC to complete and for the Forest Service to approve. The process of placing the fiber took hours to complete rather than weeks that would have been required without use of the drone, a significant cost and time savings.[vi]


The new broadband service was connected to Union County’s cameras in early 2019, and now the county has better connection to the video feeds, with up to 100 frames of a single vehicles passing through the area, much closer to a full motion video than the delayed communications previously.[vii] GDOT’s camera and road weather information system (RWIS) at the location are also being connected to the new broadband connection. This will provide better and more timely information to state and local agencies.[viii] (See “Georgia’s Connected Data Platform” for more information on the state’s ITS network.)

The GDOT camera at Neels Gap can be moved remotely to zoom, tilt, pan and view a larger area, while the county’s cameras are fixed in place and pointed toward the roadway. With improved broadband allowing for better quality video transmission, the GDOT camera might become an asset in the future for other public safety purposes, as officials conduct about 10 searches per year for hikers who are lost along the Appalachian Trail in that area.[ix]


For Union County, procuring the cameras cost approximately $1,500. Eventually, the cameras will need to be replaced. The county pays Blue Ridge Mountain EMC about $50 per month to maintain a broadband subscription to the cameras. County staff anticipate being able to learn more about the information they can access from GDOT’s ITS assets at Neels Gap, but other than some staff time provided by GDOT and Union County, that should not require significant resources devoted to training or influence staffing levels.[x]
