How It Works

Statewide Transportation Improvement Program (STIP)

The Statewide Transportation Improvement Program (STIP) lists statewide planned projects and assigns funding over a four-year period. It includes the 24 regional Transportation Improvement Programs (TIPs) and two statewide-managed TIPs (Interstate Management Program TIP and Statewide Initiatives TIP). 

Who creates it?

PennDOT combines the 24 regional, two statewide-managed TIPs, and Eastern Federal Lands (EFL) TIP  to create the STIP. PennDOT submits the draft STIP to the Federal Highway Administration, Federal Transit Administration, and the US Environmental Protection Agency for review and approval.

When is it updated?

The STIP is updated every two years after the regional TIPs are submitted and approved. The draft 2027 STIP is currently available for public review. The Public Comment Period for the draft is ongoing from June 15 – 30, 2026.




What laws and regulations are involved?

How does it impact the planning process?

The STIP makes up the first four years of the 12-Year Program (TYP).
