U.S. Route 522 In Maryland

U.S. Route 522 (US 522) is a part of the U.S. Highway System that runs from Powhatan, Virginia to Selinsgrove, Pennsylvania. In Maryland, it runs 2.35 miles (3.78 km) from the West Virginia state line at the Potomac River north to the Pennsylvania state line within Hancock in western Washington County. US 522 crosses Maryland at its narrowest north–south point, meeting Maryland Route 144 (MD 144), Interstate 70 (I-70), US 40, and I-68 before entering Pennsylvania concurrent with I-70. It is part of the National Highway System for its entire length in Maryland.

Warfordsburg Road from US 40 (now MD 144) north to Pennsylvania was paved around 1920 and designated US 522 in the late 1920s. US 522 was extended south into West Virginia shortly after a new bridge was completed over the Potomac River in the late 1930s. It was moved onto I-70 north of Hancock when the Interstate highway was completed in the area in the mid 1960s.
