Ohio State Route 118 (SR 118) is a long north–south state highway in western Ohio, connecting the cities of Greenville and Van Wert. SR 118 runs northward through Darke, Mercer and Van Wert counties, starting from a roundabout with SR 49, SR 571, SR 121 and SR 502 in Greenville. The route crosses through the farming villages of Ansonia, St. Henry, Rossburg and Ohio City as well as the villages of Coldwater and Rockford. Just north of Rossburg, SR 118 serves Eldora Speedway, a clay oval racetrack owned by NASCAR driver Tony Stewart. The northern terminus of SR 118 is at a junction with U.S. Route 127 in the city of Van Wert. Route description Darke County SR 118 begins at a roundabout with SR 49 (South Broadway), SR 121 (East Main Street), SR 502 (West Main Street) and SR 571 in the city of Greenville. After the roundabout, SR 118, SR 49 and SR 571 are concurrent along South Broadway, a two lane commercial street through Greenville . The moniker changes to North Broadway near the junction with East Water Street, passing south of Treaty of Greenville State Park. Just to the northwest of the park, SR 49 and SR 571 turn west along North Main Street while SR 118 turns north on North Broadway. After North Main, the route is a two-lane residential street, passing numerous housing complexes on each side of the roadway. North of Harke Drive, SR 118 leaves the city of Greenville. Now in the rural sections of Darke County north of Greenville, SR 118 continues north, crossing County Road 33 (CR 33, named Children's Home–Bradford Road). For several miles, the route passes farms, paralleling a railroad line to the north into the village of Ansonia. In Ansonia, SR 118 gains the South Main Street moniker, becoming a two-lane residential street through the village, crossing a railroad line in the center of the community. Several blocks north of the railroad tracks, SR 118 meets an intersection with SR 47 (Canal Street). The route then crosses the Stillwater River and its north fork, which marks the northern end of Ansonia. SR 118 continues north through the farms of Darke County, crossing the North Fork of the Stillwater River once again just south of a junction with CR 94 (Brown Road). SR 118 and the North Fork now parallel each other, continuing north through the county. After
