State Route 104 (Ohio) is a north–south state highway in the U.S. state of Ohio. It runs from Cincinnati in the south through portions of southern and central Ohio to Perrysburg near Toledo. The route connects major corridors including US 52, Interstate 71, US 23, and I-75, serving urban centers, county seats, and industrial areas.
State Route 104 begins in Cincinnati near the Ohio River and proceeds north through neighborhoods adjacent to Downtown Cincinnati and landmarks such as Cincinnati Union Terminal and Queensgate. It intersects US 52 and crosses into Clermont County near Batavia, connecting to I-275 and providing access toward Dayton and Columbus. The highway continues through Brown County toward Pike County, passing near Georgetown and Waverly where it meets US 23 and SR 32 corridors that head to Chillicothe and Portsmouth.
In Ross County and Pickaway County, SR 104 serves rural communities and farmland, intersecting US 35 and providing a link to I-70 and Columbus suburbs. The route continues through Fairfield County and Licking County near Lancaster and Heath, with connections to I-77 and US 40. Into Knox County and Richland County, SR 104 approaches Mansfield and intersects US 42 and US 30. The northern terminus in Wood County near Perrysburg provides access to Toledo and connects with I-75 and US 20.
The SR 104 designation was established in 1934 during statewide renumbering efforts guided by the Ohio Department of Transportation predecessor agencies and as part of broader changes affecting routes like US 23 and SR 4. Early alignments followed preexisting turnpikes and county roads used in the 19th century, echoing corridors linked to Ohio and Erie Canal feeder routes and stagecoach lines. Postwar improvements paralleled national programs influenced by Federal-Aid Highway Act of 1956 outcomes and connected SR 104 to federal routes such as I-71 and I-75.
Through the late 20th century SR 104 saw incremental upgrades near urban centers like Cincinnati and Mansfield with resurfacing, bridge replacements, and safety improvements influenced by standards from the American Association of State Highway and Transportation Officials and traffic engineering research at institutions like Ohio State University. Major projects included realignments to bypass small downtowns, coordination with Ohio turnpike planning, and interchange construction at nodes with I-275 and US 23.
Key intersections along SR 104 include its southern junction with US 52 in Cincinnati, interchanges with I-275 near Batavia, connections with US 52 and SR 32 toward Chillicothe, a junction with US 23 near Waverly, crossings of US 35 and I-70 corridors, intersections with US 40 and US 42, and the northern terminus connecting with I-75 and US 20 near Perrysburg. These intersections tie SR 104 into networks reaching Dayton, Columbus, Toledo, and Cleveland via linked routes.
Planned projects managed by the Ohio Department of Transportation and regional planning commissions aim to address congestion, safety, and pavement conditions on SR 104. Proposals include interchange modernization near I-275, bridge rehabilitation informed by standards from the Federal Highway Administration, and corridor studies coordinated with metropolitan planning organizations in Cincinnati and Toledo. Funding discussions reference federal programs like the Infrastructure Investment and Jobs Act and state capital budgets, while local initiatives may involve Ohio Turnpike and Infrastructure Commission coordination for freight access improvements serving industries tied to Port of Toledo and Ohio manufacturing centers.
SR 104 intersects and parallels several state and U.S. routes including SR 32, US 23, US 52, US 35, and I-275. The corridor has been subject to auxiliary designations, truck routings near Mansfield and bypasses implemented similarly to practices on routes like SR 4 and SR 1 (historic). Maintenance and signage follow standards set by Manual on Uniform Traffic Control Devices adoption in Ohio and coordination with county engineering offices across Hamilton County through Wood County.
