Route description
Along its path through Ohio, Interstate 70 passes through the following counties: Preble, Montgomery, Clark, Madison, Franklin, Fairfield, Licking, Muskingum, Guernsey and Belmont County. As an Interstate highway, by default, Interstate 70 is a part of the National Highway System, a network of highways deemed most important for the country's economy, mobility and defense.[2]
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.
