Interstate 70 marker

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

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

The portion of I-70 between I-675 and Enon Road in Clark County is designated as the "Deputy Suzanne Hopper Memorial Highway", in honor of a Clark County Sheriff's deputy who was shot and killed on January 1, 2011 while responding to reports of gunshots at a mobile home park on Enon Road, near I-70.

I-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 Road (US 40), the main east–west route through the heart of the state, built closely parallel to, but on a separate alignment from, 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.
