U.S. Route 15 is a north-south U.S. Highway in Pennsylvania.

Route description

US 15 enters Pennsylvania south of Gettysburg, Adams County, from Frederick County, Maryland, on a freeway alignment. The route heads to the north and bypasses Gettysburg, where the route interchanges with US 30. The freeway alignment ends temporarily at York Springs, carrying US 15 on a four-lane, divided alignment until the route upgrades to a freeway again in Dillsburg. The route continues toward Harrisburg, where the freeway terminates again as US 15 joins with US 11. The two routes follow the west shore of the Susquehanna River with limited-access sections until they split across the river from Sunbury. US 15 continues north into Williamsport, joining I-180 and US 220. At I-180's western terminus, US 220, signed south, heads due west toward Jersey Shore and Lock Haven, while US 15 turns due north through Mansfield and crosses into New York near Lawrenceville, Tioga County.

The majority of US 15 is four lanes, alternating between limited and unlimited access. The one leg that is only two lanes is between White Deer and South Williamsport. The segment between Williamsport and the New York state line will eventually be designated Interstate 99.

History

Prior to 1941, US 15 ran along the east bank of the Susquehanna River between Harrisburg and Williamsport while the road on the western bank of the river was PA 14 between Lemoyne and Duncannon, US 11 between Duncannon and Shamokin Dam, and PA 404 between Shamokin Dam and Williamsport.^[2] In 1941, US 15 was rerouted to follow the western bank of the river between Harrisburg and Williamsport, replacing PA 14 between Lemoyne and Duncannon, running concurrent with US 11 between Lemoyne and Shamokin Dam, and replacing the entire length of PA 404. The former alignment of US 15 on the east side of the river became PA 14.^[3][4]
