State highway in Pennsylvania, US
Pennsylvania Route 533 (PA 533) is a 21.7-mile-long (34.9 km) state highway located in Franklin and Cumberland counties in Pennsylvania. The western terminus is at State Route 4004 (SR 4004) at a junction with Mountain Road, Valley Road, and Community Road in the community of Upper Strasburg in Letterkenny Township. The eastern terminus is at PA 233 in Newville. PA 533 heads east from Upper Strasburg as a two-lane undivided road through farmland, passing to the north of Letterkenny Army Depot before crossing PA 997 in Pleasant Hall. The route continues east and crosses PA 433 in Orrstown before reaching Shippensburg, where it reaches U.S. Route 11 (US 11). Here, PA 533 becomes concurrent with US 11 and intersects PA 696 in the downtown area and PA 174 upon leaving Shippensburg. PA 533 splits from US 11 and runs northeast through more agricultural areas before reaching Newville.
The section of road between Upper Strasburg and Pleasant Hall was designated as part of PA 333 in 1928. PA 533 was designated in 1930 to run from PA 433 in Orrstown east to US 11 in Shippensburg. The same year, PA 633 was designated to run from Upper Strasburg east to PA 333 (now PA 997) in Pleasant Hall after PA 333 was realigned. In 1937, PA 533 was extended west to PA 944 in Upper Strasburg, replacing all of PA 633, and extended east to PA 233 in Newville. The intersecting PA 944 designation was removed from the western terminus in the 1940s.
