town, US 522 and WV 9 pass by Berkeley Springs State Park and the Morgan County Courthouse. In the northern part of town, WV 9 splits west onto Union Street to cross Warm Spring Ridge, and the U.S. Highway continues north and passes the historic Berkeley Springs Train Depot. US 522 heads north from Berkeley Springs on Hancock Road, which parallels Warm Spring Run and a CSX rail spur through North Berkeley, Jimtown, and Burnt Factory. North of Burnt Factory, the highway descends into the narrow valley of the Potomac River; southbound US 522 has a climbing lane. US 522's bridge across the Potomac River begins just north of River Road; the highway crosses over CSX's Cumberland Subdivision's Hancock rail yard and, on the bridge itself, has its last junction in West Virginia, with Airport Road, which leads to Potomac Airpark in the West Virginia hamlet of Hancock. The bridge crosses into Washington County, Maryland and the town of Hancock at a narrow channel of the Potomac, crosses an island, then crosses the main channel of the river, Chesapeake and Ohio Canal National Historical Park, Berm Road, the Western Maryland Rail Trail, and South Street before the bridge lands on the Maryland side of the river. US 522, named Warfordsburg Road, meets a two-way ramp from Maryland Route 144 (Main Street) before the highway bridges MD 144, Little Tonoloway Creek, and Limestone Road, which is MD 894. US 522 becomes a divided highway just south of its right-in/right-out junction with High Street, which leads to MD 144 via Virginia Avenue. Southbound US 522 has an exit ramp to Limestone Road used to access MD 144. US 522 meets I-70 and US 40 (Eisenhower Memorial Highway) at a three-level directional-T interchange where US 522 becomes concurrent with the two highways. Immediately to the north, I-70 and US 522 meet the eastern terminus of I-68 (National Freeway) at another three-level directional interchange, where westbound US 40 leaves I-70 and goes onto I-68. Southbound US 522 exits I-70 via a left exit prior to US 40 joining eastbound I-70, so southbound US 522 does not have a concurrency with US 40. I-70 and US 522 continue north as a four-lane freeway that leaves the town of Hancock and crosses the Maryland–Pennsylvania state line. Hancock to Mount Union US 522 enters Pennsylvania concurrent with I-70 (Eisenhower Memorial Highway) in Bethel Township in Fulton County.
