U.S. Route 15 (US 15) is United States Numbered Highway that runs from Walterboro, South Carolina, north to Painted Post, New York. In Pennsylvania, the highway runs for 194.89 miles (313.65 km), from the Maryland state line just south of Gettysburg, north to the New York state line near Lawrenceville.
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 has an interchange with US 30. The freeway alignment ends at York Springs, carrying US 15 on a four-lane, divided alignment with at-grade intersections until the route upgrades to a freeway again in Dillsburg. The route continues north toward Harrisburg, where the freeway terminates again as US 15 joins with US 11. The two routes begin to 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 Interstate 180 (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. There are two segments where the road is two lanes. One is from East Pennsboro Township, Cumberland County, just north of the I-81 interchange, to just south of Duncannon. The other is between White Deer and South Williamsport. The segment between Williamsport and the New York state line will eventually be designated I-99.
The entire length of US 15 in Pennsylvania is part of the National Highway System.[2]
History

---|---|
Existed | 1928–1941 |
With the adoption of the U.S. Numbered Highway System, US 15 originally terminated at Harrisburg, while US 111 serviced the modern route north of that point. In 1937, US 15 was extended north to the New York state line, effectively replacing US 111 north of Harrisburg. However, instead of replacing US 111's old routing directly, 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 Pennsylvania Route 14 (PA 14) between Lemoyne and Duncannon, US 11 between Duncannon and Shamokin Dam, and PA 404 between Shamokin Dam and Williamsport.[3] 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.[4][5]
On June 28, 1963, the US 15 bypass of Gettysburg was opened to traffic, with the former alignment through Gettysburg becoming US 15 Bus. The project to construct the bypass cost $8 million. No formal ceremony was held to mark the opening of the highway, as it was felt local officials were too busy preparing for events related to the centennial of the Battle of Gettysburg.[6][7]
On November 17, 2009, US 15 was widened to four lanes across Steam Valley Mountain in northern Lycomimg County with the opening of the new southbound lanes. In addition, interchanges were constructed at PA 184 and Green Mountain Road/Steam Valley Road. A ribbon-cutting ceremony attended by local officials was held.[8]
Future
The section of US 15 north of Williamsport will gain the additional designation of I-99 when the connection from I-76 to I-86 is completed. No additional work is needed to upgrade this stretch, as it is already up to Interstate standards.[9]
As part of the construction of the Central Susquehanna Valley Thruway, US 15 is planned to be rerouted to the new freeway between Selinsgrove and Union Township, bypassing Shamokin Dam. The former alignment of US 15 through Shamokin Dam will be designated as US 15 Business, partly running concurrent with US 11.[10]
