{{Main|Interstate 70 in Ohio}}
I-70 enters [[Ohio]] just east of the interchange with US&nbsp;40 at [[Richmond, Indiana]]. Immediately to the east of this border, travelers notice a unique teal-blue arch that spans the width of the freeway, with a "Welcome to Ohio" greeting sign above the eastbound lanes. A sign thanking travelers for visiting Ohio is mounted on the other side of the arch for westbound travelers. Continuing eastbound, I-70 intersects [[Interstate 75|I-75]] north of [[Dayton, Ohio|Dayton]], followed by [[Interstate 675 (Ohio)|I-675]] on the east side of Dayton. [[Springfield, Ohio|Springfield]] is the next city, the site of [[Buck Creek State Park]].

I-70 then encounters [[Columbus, Ohio|Columbus]]. Columbus is bounded by [[Interstate 270 (Ohio)|I-270]] and is roughly centered on the intersection of I-70 and [[Interstate 71|I-71]], which share the same asphalt through a notoriously congested {{convert|1.5|mi|km|adj=on}} stretch locally known as the "South Innerbelt" or, more commonly, "The Split". This stretch has I-71 concurrent with I-70, where I-71 enters and exits from opposite sides of I-70, causing traffic getting on I-70 from I-71 northbound to have to cross four lanes of I-70 traffic to continue on I-71. A similar issue is present for southbound I-71 traffic as well. The Split is being reconstructed ($1.4&nbsp;billion) and is scheduled to be completed by mid-2026. [[Interstate 670 (Ohio)|I-670]] connects [[John Glenn Columbus International Airport]] with I-270, I-71, and I-70. East of Columbus, I-70 passes through [[Zanesville, Ohio|Zanesville]] and on to [[Cambridge, Ohio|Cambridge]], where it intersects [[Interstate 77|I-77]]. Continuing on toward [[West Virginia]], I-70 intersects [[Interstate 470 (Ohio–West Virginia)|I-470]] just east of [[St. Clairsville, Ohio|St. Clairsville]]. I-470 is primarily used for through traffic and to avoid The Winter Festival of Lights traffic during the [[Christmas season]] from [[Oglebay Park]]. In March 1995, a hole (from a former coal mine) opened up on the eastbound side of I-70 in [[Guernsey County, Ohio|Guernsey County]] near [[Old Washington, Ohio|Old Washington]] and caused traffic to be rerouted onto US&nbsp;40 between Old Washington and Cambridge for several months.
