Decatur County SR-100 lane closures for shoulder repairs with temporary signals

Traffic on SR-100 in Decatur County is currently restricted while crews stabilize the highway shoulder at two locations, and temporary signals are controlling alternating traffic. The work affects the stretch between Hughes Road and Mt. Zion Road at LM 1.3 and the stretch between Cooper Branch Road and Tillman Road at LM 5.1, with active lane closures and signals designed to keep traffic moving safely through single-lane operations.

For the segment near Hughes Road and Mt. Zion Road, the closure began at 8:00 a.m. on January 20 and is scheduled through 6:00 p.m. on January 27. For the segment between Cooper Branch Road and Tillman Road, operations began at 8:00 a.m. on January 27 and will continue through 6:00 p.m. on February 6. Both locations are being managed with temporary traffic signals to alternate vehicle flows while crews work on shoulder stabilization. "There will be lane closure in place on SR100 between Hughes Road and Mt. Zion Road at LM 1.3, controlled by a temporary traffic signal, for crews to stabilize the shoulder of SR100. The temporary signal is currently installed and flashing." "There will be a lane closure in place on SR100 between Cooper Branch Road and Tillman Road at LM 5.1, controlled by a temporary traffic signal, for crews to stabilize the shoulder of SR100. The temporary signal is currently installed and flashing."

The immediate impact will be slower travel times for commuters, school buses, delivery vehicles, and emergency responders using SR-100. Motorists should expect alternating traffic and short delays through the single-lane sections, particularly during morning and evening peak periods. Local businesses that rely on steady passing traffic should plan for intermittent slowdowns and coordinate deliveries outside the work windows where possible.

This maintenance work highlights routine infrastructure stewardship and the tradeoffs communities face between short-term disruption and long-term roadway safety. Shoulder stabilization reduces the risk of erosion, pavement edge failures, and hazards to vehicles that drift from the travel lane, but the scheduling and communication of closures influence daily routines and emergency planning. Local officials and county voters will see these projects as part of ongoing decisions about maintenance budgets and prioritization of state and county routes.

Drivers can reduce delay by allowing extra travel time, avoiding SR-100 during peak hours if alternate routes are available, and obeying temporary signals and reduced speed zones for the safety of workers. Expect the temporary signals to remain in use while crews complete stabilization through the posted end dates, with the second phase concluding on February 6 at 6:00 p.m. The work aims to restore full shoulder integrity and safer travel along SR-100 for Decatur County residents in the weeks ahead.
