In the U.S. state of Ohio, Interstate 80 (I-80) runs across the northern part of the state. Most of the route is part of the Ohio Turnpike, with only an 18.78-mile (30.22 km) stretch not being on the toll road. That stretch of road is the feeder route to the Keystone Shortway, a shortcut through northern Pennsylvania that provides access to New York City.
In Ohio, I-80 enters with I-90 from the Indiana Toll Road and immediately becomes the "James W. Shocknessy Ohio Turnpike", more commonly referred to as simply the Ohio Turnpike. The two Interstates cross rural northwest Ohio and run just south of the metropolitan area of Toledo. In Rossford, Ohio the turnpike intersects with Interstate 75 in an area known as the Crossroads of America. This intersection is one of the largest intersections of two Interstate Highways in the United States.
In Elyria Township, just west of Cleveland, I-90 splits from I-80 (leaving the turnpike and running northeast as a freeway). I-80 runs east-southeast through the southern suburbs of Cleveland and retains the Ohio Turnpike designation. Just northwest of Youngstown, the Ohio Turnpike continues southeast onto Interstate 76, while I-80 exits the turnpike and runs east to the north of Youngstown, entering Pennsylvania south of Sharon, Pennsylvania.
Most of Interstate 80 was constructed as part of the Ohio Turnpike, the origins of which predate the establishment of the Interstate Highway System in 1956. The Ohio state legislature created the Ohio Turnpike Commission in 1949, which was the first step in designing and constructing the east-west freeway. Construction began on October 27, 1952, and the freeway was completed on October 1, 1955 (a total of 38 months).
Although I-80 presently uses the Ohio Turnpike across most of the state, it was once planned to split between Norwalk and Edinburg, with Interstate 80N passing through Cleveland and Interstate 80S passing through Akron.
