Signal type 1 lats carbon reduction project - signal retiming - US 278 moss creek - university parkway

The Federal Highway Administration (FHWA) awarded $153,000 through the Highway Planning and Construction program (CFDA 20.205) to the South Carolina Department of Transportation on May 15, 2025. This Formula Grant funds the Signal Type 1 LATS (Local Adaptive Traffic Signal) Carbon Reduction Project, which involves signal retiming operations at the US 278 intersection near Moss Creek and University Parkway in South Carolina. The project delivers traffic signal optimization services designed to reduce vehicular emissions and improve traffic flow efficiency at this critical highway junction.

The award supports infrastructure improvements aligned with the Federal-aid Highway Program's objectives to enhance transportation safety and environmental sustainability. Signal retiming represents a cost-effective intervention within the FHWA's Carbon Reduction Program framework, utilizing intelligent transportation systems technology to minimize carbon emissions without requiring major capital reconstruction. As a state-administered program, the South Carolina Department of Transportation manages implementation in accordance with federal planning, environmental review, and oversight requirements established under 23 CFR and 49 CFR regulations.
