HARRISBURG, PA — Pennsylvania is pouring nearly $30 million into traffic signal upgrades statewide, with Chester County communities set to receive almost $1.5 million aimed squarely at easing congestion and improving safety on some of the region’s busiest corridors.
The funding, announced by the Shapiro administration, will support 57 municipalities across 24 counties through the Green Light-Go Program, which reimburses local governments for projects that modernize existing traffic signals. Since Governor Josh Shapiro took office, the program has delivered $96 million to municipalities statewide.
In Chester County, the awards target long-familiar choke points for commuters and residents. Upper Uwchlan Township received the largest local grant, $920,306, to upgrade traffic signal detection and controller equipment at the heavily traveled intersection of Route 100 and Graphite Mine Road. West Whiteland Township was awarded $389,640 to modernize multiple intersections along Route 100 and Commerce Drive, a key commercial artery. East Whiteland Township will receive $191,870 to modernize the intersection of Lancaster Avenue and Conestoga Road, a corridor central to daily traffic and regional travel.
State officials said many of the projects will deploy modern signal detection and control technologies that allow traffic lights to respond to real-time conditions, reducing backups while improving safety for drivers, pedestrians, and cyclists.
“Under Governor Shapiro’s leadership, our top priority is serving the people of our Commonwealth by improving the services that make a real difference in Pennsylvanians’ lives,” PennDOT Secretary Mike Carroll said. He added that the Green Light-Go investments are designed to reduce congestion, improve traffic flow, and keep travelers moving safely and efficiently.
Across Pennsylvania, the funding spans dense urban centers and smaller boroughs alike. Philadelphia alone will receive more than $5.7 million to upgrade hundreds of traffic controllers and modernize multiple intersections. Large allocations are also headed to Erie County, Montgomery County, Allegheny County, and other regions facing persistent congestion challenges.
The grants are funded through the fiscal year 2025–26 state budget and support a range of eligible improvements, including LED signal installations, traffic signal retiming, special-event traffic planning, system monitoring, and upgrades to adaptive signal technology.
The announcement follows a separate release in late December in which the administration awarded more than $47 million through the Multimodal Transportation Fund for highway, bridge, bicycle, and pedestrian projects statewide, signaling a broader push to modernize Pennsylvania’s transportation infrastructure.
For Chester County residents, officials say the Green Light-Go funding translates into fewer red-light delays, smoother commutes, and safer intersections along routes that thousands rely on every day.
