Although PennDOT crews are common sights on Pennsylvania's 40,000 roadway miles and 25,000 bridges, many of our customers may not realize the scope of work we do. The Maintenance First series was developed to shed some light on the operations PennDOT performs year-round in our mission to provide an efficient transportation system. You can also see how potholes are formed (PDF).
