In the U.S. state of Pennsylvania, state highways are generally maintained by the Pennsylvania Department of Transportation (PennDOT). Each is assigned a four-digit State Route (SR) number in the present Location Referencing System. Traffic Routes are signed as Interstate Highways, U.S. Routes and Pennsylvania Routes (PA Routes), and are prefixed with one to three zeroes to give a four-digit number. PA Routes are also called Pennsylvania Traffic Routes, and formerly State Highway Routes.[2]
There are 41,643 mi (67,018 km) of roadway maintained by state agencies, with 39,737 mi (63,951 km) maintained by PennDOT, 554 mi (892 km) maintained by the Pennsylvania Turnpike Commission, and 1,352 mi (2,176 km) maintained by other state agencies.[1]
