Germantown Pike is a historic road in Pennsylvania that opened in 1687, running from Philadelphia northwest to Collegeville. The road is particularly notable for the "imposing mansions" that existed in the Germantown neighborhood in Philadelphia. The road was left in ruins after the British destroyed it in the Revolutionary War during the 1777 Battle of Germantown, and was not rebuilt until 1809. Portions of Germantown Pike were signed as U.S. Route 422 (US 422) before the latter was rerouted along a freeway alignment to King of Prussia.

U.S. Route 202 is a US Highway running from New Castle, Delaware, northeast to Bangor, Maine. In the U.S. state of Pennsylvania, the route runs for 59 miles (95 km), from the Delaware state line in Bethel Township, Delaware County, to the New Hope–Lambertville Toll Bridge over the Delaware River in Solebury Township, where the route crosses into New Jersey. The highway runs through the western and northern suburbs of Philadelphia in the Delaware Valley metropolitan area, and serves as a toll-free bypass around the city, avoiding the busy traffic and congestion on Interstate 95 (I-95). It is signed north–south and follows a general southwest–northeast direction through the state.
