Ohio State Route 18

SR 18 Business

State Route 18 Business (SR 18 Bus.) is a business route through the village of North Baltimore in southern Wood County. The route starts at a T-intersection with SR 18 in Henry Township and runs east into North Baltimore on Deshler Road and West State Street. In the center of the village, the route heads south onto South Main Street. SR 18 Bus. ends at a roundabout with SR 18 in the southern limits of the village.

SR 18 Bus. was created in November 2012 along what used to be SR 18 through North Baltimore. When SR 18 was rerouted on a bypass of the village in 2012, the old route became a signed business route.
