2027 Transportation Program: $90 billion investment over 12 years
The State Transportation Commission (STC) has adopted the 2027 12-Year Transportation Program (TYP), a plan reflecting an anticipated investment of over $90 billion over the next 12 years for improvements to roads, bridges, transit systems, airports, railroads and active transportation.
That represents an increase of more than 3% from the 2025 TYP.
The plan includes a number of projects that will benefit travelers in the West Hills, including efforts in Carnegie, Coraopolis, Crafton, McKees Rocks, Neville, Robinson, Rosslyn Farms and Stowe.
Local projects included in the 12-year plan include drainage improvement work in Carnegie, pedestrian facilities in Coraopolis, streetscaping and pedestrian facilities in Crafton, phase 3 of the McKees Rocks Bridge preservation project, traffic safety improvements in Neville, Steubenville Pike resurfacing, Campbells Run Road reconstruction and the Diverging Diamond interchange project over Routes 22-30 in Robinson, Rosslyn Farms Parkway entrance, and Stowe Tunnel restoration work.
In the first four years of the TYP, beginning Oct. 1, the newly adopted program anticipates the following funding to be available statewide from federal, state and local sources:
- $16.9 billion for state highway and bridge projects.
- $12.9 billion for public transit.
- $367 million for multimodal projects.
- $240 million for rail freight.
- $154 million for aviation
The TYP includes statewide planned projects across all modes of transportation, and reflects funding assigned to these projects over a 12-year period.
Now that the STC has adopted the update, the state Department of Transportation (PennDOT) will submit the plan to the Federal Highway Administration and the Federal Transit Administration for review. The FHWA coordinates with the U.S. Environmental Protection Agency to review the plan’s conformity with air quality requirements.
