The Ohio Turnpike, officially the James W. Shocknessy Ohio Turnpike, is a limited-access toll highway in the U.S. state of Ohio, serving as a primary corridor between Chicago and Pittsburgh. The road runs east–west in the northern section of the state, with the western end at the Indiana–Ohio border near Edon where it meets the Indiana Toll Road, and the eastern end at the Ohio–Pennsylvania border near Petersburg, where it meets the Pennsylvania Turnpike. The road is owned and maintained by the Ohio Turnpike and Infrastructure Commission (OTIC), headquartered in Berea. Built from 1949 to 1955, construction for the roadway was completed a year prior to the Interstate Highway System. The modern Ohio Turnpike is signed as three Interstate numbers: I-76, I-80, and I-90. Route description The entire length of the Ohio Turnpike is , from the western terminus in Northwest Township near Edon, where it meets the Indiana Toll Road at the Ohio–Indiana border, to the eastern terminus in Springfield Township near Petersburg where it meets the Pennsylvania Turnpike at the Ohio–Pennsylvania border. Most of the turnpike, between the Indiana border and an interchange with Interstate 76 (I-76) near Youngstown, is signed as part of I-80, while the eastern , between the I-80/I-76 interchange and the Pennsylvania border, is signed as part of I-76. For , between the Indiana border and Elyria, I-90 is cosigned with I-80 as part of the turnpike. The Ohio Turnpike does not pass directly into any major city, but does provide access to the four major metro areas in northern Ohio through connected routes. Two auxiliary Interstate highways, I-271 near Cleveland and I-475 near Toledo, cross the turnpike, but do not have direct connections. In Northwest Ohio, the turnpike passes through the southern part of the Toledo metropolitan area, with direct access to Toledo through I-75 and I-280. In Northeast Ohio, the turnpike passes through the southern suburbs of Greater Cleveland and the northern edge of the Akron metro area, with direct access to Cleveland via I-71, I-77, I-90 and I-480. Akron is connected to the turnpike via I-77 and State Route 8 (SR 8) in the north and I-76 on the east. The turnpike is located on the western and southern edges of the Mahoning Valley, with direct access to Youngstown through the remaining portion of I-80 east of the Turnpike, and I-680. In North Jackson, I-80 and I-76 swap each other's right-of-way;
