Research, Planning & Innovation

Keeping PA roadways safe and future-ready for travelers and workers is one of PennDOT's top priorities. 

 

With nearly 40,000 miles of roadway and 25,000 bridges maintained by PennDOT, the department works with local governments, the private sector, planning partners and others to maintain the state's transportation network. These resources provide information needed from the project planning stage through improvement completion.
