Built from 1949 to 1955, the Ohio Turnpike, officially the James W. Shocknessy Ohio Turnpike, is a 241.26-mile-long (388.27 km) limited-access tollway serving as a primary corridor to Chicago and Pittsburgh. It runs east–west from the Indiana Toll Road (at the Indiana–Ohio border near Bryan) to the Pennsylvania Turnpike (at the Ohio–Pennsylvania border near Petersburg).

Today the Ohio Turnpike has three interstate numbers: I-76, I-80, and I-90.
