The Pennsylvania State Transportation Commission (STC) was established by PA State Law, Act 120 of 1970, which also created the Pennsylvania Department of Transportation (PennDOT).
The STC determines and evaluates the condition and performance of Pennsylvania’s transportation system in order to effectively assess the resources required to preserve, restore, extend and expand transportation facilities and services. The STC is also actively focused on the conservation of Pennsylvania’s communities and economic development. In addition, State law requires PennDOT to prepare an update to Pennsylvania’s Twelve Year Transportation Program every two years for submission to the STC. The Transportation Program must be multimodal and fiscally-constrained.
A key component of the Twelve Year Transportation Program (TYP) update process is public involvement. The STC actively seeks input from the public during this transportation planning process as well as throughout each calendar year. Opportunities to share your feedback with the STC include:
