In Pennsylvania in the early 1960s, a four-lane expressway, the Piedmont Expressway, was proposed that would follow the US 202 corridor. The expressway was to be long, and would cost approximately $146 million. It was to serve as an outer beltway around the Philadelphia area. The project was ultimately cancelled. In its place, the Route 202 Parkway Trail was built. The trail is in length. The trail is ultimately expected to connect to the East Coast Greenway via the Neshaminy Creek Trail.
