The Town appreciates your patience as SCDOT completes these important infrastructure improvements.
Fort Mill is investing in long-term solutions to improve traffic operations throughout our community. The Town has been awarded a Congestion Mitigation and Air Quality (CMAQ) Grant through the Rock Hill-Fort Mill Area Transportation Study Group (RFATS) to design, engineer and construct an Adaptive Traffic Control System in coordination with SCDOT. Once implemented, the system will continuously monitor traffic conditions and automatically adjust traffic signal timing in real time to improve traffic flow, reduce congestion, minimize unnecessary stops, and enhance travel during peak periods, special events, incidents, and roadway construction.
The design, engineering and construction of the adaptive traffic control system is expected to take approximately 18 months to complete.
The Town appreciates RFATS, S.C. Rep. David Martin, Sen. Michael Johnson, and SCDOT for their support of this important transportation project.
