U.S. Route 101
The nearly highway's northern terminus is in Tumwater, Washington: the route remains along the Olympic Peninsula's coastal perimeter west, north, and east; the northernmost point on the highway is in Port Angeles. The southern terminus of US 101 is in Los Angeles at the East Los Angeles Interchange, the world's busiest freeway interchange.
SEPTA Routes 101 and 102
Route 101 continues on its own right-of-way traveling west and southwest through Drexel Hill and Springfield with an important stop at the Springfield Mall before entering the street in Media. The 101 has double tracks to Woodland Avenue, then a single track to just before Pine Ridge, then enters the street at Providence Road in Media and runs on a single track the rest of the way. Cars in the street must yield to the trolley. The line terminates in the middle of the street just west of the Delaware County Courthouse.
