Pennsylvania Turnpike is a 565-mile (910-kilometer) toll superhighway. It was the first successful American toll highway of any great length built for all types of motor vehicles. The turnpike’s main line runs for 360 miles (580 kilometers) across Pennsylvania, from Ohio to New Jersey. The Northeastern Extension runs for 110 miles (177 kilometers) from a point near Norristown to an area north of Scranton. Extensions of the highway in western Pennsylvania add about 95 miles (153 kilometers) to the turnpike system. The turnpike carries about 200 million vehicles a year.
The turnpike opened in 1940. At that time, it spanned 160 miles (260 kilometers) from Irwin (near Pittsburgh) to Middlesex (near Carlisle).
