Pennsylvania Turnpike
This is one of the original service plazas for the nation's first long-distance superhighway. On October 1, 1940, the Turnpike opened, stretching 160 miles from Irwin to Carlisle. The Turnpike Commission had been created in 1937; construction utilized the old South Pennsylvania Railroad's right-of-way and tunnels. By 1957 the Turnpike spanned 360 miles across the State and extended 110 miles north to Scranton.
