In the state of Ohio, Interstate 74 runs southeast from the Indiana border to the western segment's current eastern terminus at Interstate 75 just north of downtown Cincinnati. It is also signed with U.S. Route 52 for its entire length.
The unbuilt portion of Interstate 74 in Ohio is expected to be routed along Ohio State Route 32, U.S. Route 23, and U.S. Route 52 for most of its length. However, the routing for the segment through Cincinnati, connecting Interstate 75 to Ohio State Route 32, remains a matter of dispute. A likely scenario has Interstate 74 running with northbound Interstate 75 from Exit 4 to Exit 7, then turning east along short Ohio State Route 562, known as the Norwood Lateral Expressway, for the three miles to Interstate 71. However, building a connection between Interstate 71 and the western terminus of Ohio State Route 32 at U.S. Route 50 would pose some difficulty: the most direct route, two-lane Ohio State Route 561, runs through several densely populated neighborhoods.
