Interstate 74 (I-74) in the U.S. state of Ohio runs for 19.47 miles (31.33 km) 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.

Route description[]

The Ohio portion of Interstate 74 begins on the Indiana border near Harrison and travels east. Shortly after crossing into Ohio, the interstate curves southeast before it intersects with Interstate 275 near milepost 5. It then overlaps with that beltway route, heading generally east for approximately 4 miles before splitting from I-275 to continue southeast into Cincinnati. Approximately 10 miles later I-74 reaches its eastern terminus at Interstate 75, about 4 miles north-northwest of downtown Cincinnati.

Future[]

Long term plans call for Interstate 74 to be continued through Ohio and into West Virginia, concurrent with Interstate 73; with both of these roads continuing through Virginia and North Carolina to end in Myrtle Beach, South Carolina. Due to funding concerns, there are no concrete plans for this to occur.

However, several plans are in the running for the extension through the Cincinnati metro area. They include:
1. Run along Interstates 75 and 275, then onto Ohio 32;
2. Interstate 75 between I-74/75 interchange and I-75/Ohio 562 interchange, then onto Ohio 562, Interstate 71 between Ohio 562 and Red Bank corridor, down the Red Bank corridor, and along a new highway connector to Ohio 32; and
3. I-74/75 interchange to I-75/Ohio 562 interchange, then onto Ohio 562, then along Interstates 71 and 275 before connecting to Ohio 32.

The second route was eliminated due to opposition regarding a key part of its completion: a $366.2 million highway that would need to be constructed near Mariemont and Newtown (termini: Red Bank Road/Wooster Pike intersection and Bells Lane). Total costs would have been $809.1 million ($62 million per mile). Improvements to existing roads have been proposed instead.

The Norwood Lateral (Ohio State Route 562) would need to be reconstructed in order to become part of Interstate 74. It needs the following: a third travel lane in each direction (two each currently), overpasses that would need more vertical clearance (16 feet minimum), upgraded ramp extensions at interchanges (1200 feet) and shoulders that might need more width. There are highways with shoulder widths of four and eight feet, however; so this might not be a serious issue. This problem could be resolved through the U.S. Congress if they wanted to designate the Norwood Lateral as a future segment of the Interstate Highway System.
