The Pennsylvania Turnpike, sometimes shortened to Penna Turnpike or PA Turnpike, is a controlled-access toll road which is operated by the Pennsylvania Turnpike Commission (PTC) in Pennsylvania. It runs for 360 miles (580Â km) across the southern part of the state, connecting Pittsburgh, Harrisburg and Philadelphia, and passes through four tunnels as it crosses the Appalachian Mountains. A component of the Interstate Highway System, it is part of I-76 between the Ohio state line and Valley Forge (running concurrently with I-70 between New Stanton and Breezewood), I-276 between Valley Forge and Bristol Township, and I-95 from Bristol Township to the New Jersey state line.
The turnpike's western terminus is at the Ohio state line in Lawrence County, where it continues west as the Ohio Turnpike. The eastern terminus is the New Jersey state line at the Delaware River–Turnpike Toll Bridge, which crosses the Delaware River in Bucks County. It continues east as the Pearl Harbor Memorial Extension of the New Jersey Turnpike. The turnpike has an all-electronic tolling system; tolls may be paid using E-ZPass or toll by plate, which uses automatic license plate recognition. Cash tolls were collected with a ticket and barrier toll system before they were phased out between 2016 and 2020. The turnpike currently has 15 service plazas, providing food and fuel to travelers.
