In the U.S. state of Ohio, Interstate 70 provides access between Indiana and West Virginia.

Route description

This section requires expansion.

From the west, Interstate 70 enters Ohio after passing through Indiana. Upon entering the state, passengers drive under a "Welcome to Ohio" arch, which also lists the names of the current governor and lieutenant governor. From here, the highway passes through the city of Dayton, Springfield, and next Columbus, the state's biggest city. After leaving Columbus, the highway heads east toward West Virginia.

History

Interstate 70 appeared on the original AASHTO interstate route numbering map from August 14, 1957. It was envisioned as a modern upgrade of the old National Pike (US-40), the main east-west route through the heart of the state, built closely parallel to, but on a separate alignment as the then overburdened and obsolete highway. The 21-mile (34 km) section between Kirkersville and Gratiot (current Exits 122 - 142), was the first new construction opened to traffic (1959). At that time, the highway was accessed at both ends via temporary at-grade intersections with the old National Pike, with I-70 and US-40 sharing the same carriageways.

Once the road was extended westward towards Columbus by 1968, access was routed to Exit 122, with the western 1-mile (1.6 km) access road continuing US-40 back to the old National Pike becoming part of OH-158 (though the westbound lanes were abandoned). The following year, the highway was opened eastward to Zanesville, with a new interchange, Exit 142, at Gratiot. The at-grade intersection with the old National Pike was subsequently blocked off, to be erased by years of overgrowth. The US-40 designation was returned to the Pike around the same time, replacing the temporary OH-440 designation.
