context_page_description: U.S. Route 322 is a spur of US 22, running from Cleveland, Ohio east to Atlantic City, New Jersey. In the U.S. state of Pennsylvania, the route runs from the Ohio border in West Shenango Township southeast to the Commodore Barry Bridge over the Delaware River in Chester, at which point the route crosses into New Jersey. The route passes near several cities, including DuBois, State College, and Harrisburg.
context_section_description: In Pennsylvania, US 322 is signed as 28th Division Highway, in honor of the 28th Infantry Division. The route enters Pennsylvania taking a northeasterly course. In Meadville, US 322 overlaps US 6 and US 19. Southeast of Meadville, the highway runs generally southeast through Crawford, Venango and Clarion Counties. Once leaving the borough of Clarion, US 322 has an interchange with I-80, at exit 70. From I-80, it continues on a solid east–west routing crossing Jefferson County. The route overlaps US 219 near the northern terminus of US 119, south of DuBois. East of US 219, the route takes a southward turn to traverse Moshannon State Forest, before taking an east–west alignment. From Clearfield to US 220, the highway runs southeast and is partly divided.
  In the State College area, the current alignment of US 322 overlaps I-99 and US 220 for 12 miles (19 km) Northeast of Port Matilda, I-99, US 220, and US 322 depart the Appalachian Thruway via an interchange and proceed east on the 28th Division Highway while the Thruway continues to the northeast as US 220 Alternate.
  West of State College, the 28th Division Highway becomes the Mount Nittany Expressway after intersecting with Scotia Road and North Atherton Street (US 322 Business, which goes through downtown State College). The I-99/US 220/US 322 overlap ends at a complex interchange north of downtown State College.
  East of the overlap, US 322 continues southeastward through State College and its immediate suburbs on the Mount Nittany Expressway. After three exits, US 322 reverts to an at-grade highway two miles east of State College in Boalsburg, merging with US 322 Business and proceeding eastward along Boal Avenue as the route exits the State College area. Between Boalsburg and Lewistown, the highway traverses Tussey Mountain and Stone Mountain, in the Rothrock State Forest, as it turns to the south.
  Between Potters Mills and Lewistown, US 322 is a limited-access road. Near Lewistown, it briefly overlaps US 522 and begins a long overlap with US 22. South of Lewistown, US 22/US 322 enters the Lewistown Narrows, an 8-mile (13 km) stretch of road through the Juniata River water gap in Shade Mountain. Construction to convert this section of the highway from a two-lane highway to a divided, limited-access four-lane highway was completed in December 2007, and it includes building the longest mechanically stabilized earth wall in the U.S. The highway exits the narrows in Arch Rock, traverses Juniata County and Perry County, and crosses the Tuscarora Mountain through a water gap on a southeastward course along the banks of the Juniata River. After crossing the Susquehanna River on the Clarks Ferry Bridge (coinciding with the Appalachian Trail), the freeway runs south and parallels the river for 15 miles (24 km) before entering the Harrisburg Area. The section of US 322 between State College and Harrisburg serves as a major access road to Pennsylvania State University from points to the southeast and experiences traffic congestion on Penn State Nittany Lions football home game days.
  North of downtown Harrisburg, the US 22/322 overlap has an interchange with I-81 at exit 67. While US 22 continues through the interchange and heads into downtown, US 322 departs US 22 and joins I-81 northbound. I-81 and US 322 remain concurrent for three miles (5 km) to exit 70, where US 322 exits, following I-83, which has its northern terminus at the interchange, south through the innermost suburbs of Harrisburg. After two exits, US 322 departs I-83 at the Eisenhower Interchange (exit 47), following Paxton Street east, returning to an at-grade roadway after one exit, toward Hummelstown. West of that borough, US 322 becomes a freeway once again, becoming the Hummelstown Bypass after crossing Fiddlers Elbow Road. The route runs south of Hummelstown, interchanging with two local roads before meeting the eastern terminus of PA 39 and the western terminus of US 422 at an interchange midway between Hummelstown and Hershey.
