Business Loop I-75 - Findlay

Some city installed signs remain posted along Main Street for Business Loop I-75 at Findley. The route is otherwise unposted and not acknowledged from the Interstate 75 mainline.

The 4.7 mile long loop departs from I-75 at Exit 156 to briefly overlap with U.S. 68 to right in / right out ramps with Lima Avenue. Lima Avenue carries the route northeast to W Lima Street for the connection with Main Street (old U.S. 25). North through Downtown, SR 37 combines with Business Loop I-75 (Main Street) from Lincoln Street while SR 12 joins the route from Main Cross Street.

North across the Blanchard River, SR 12 turns east along side U.S. 224 (Center Street) while SR37 ends. U.S. 224 west / Business Loop I-75 overlap northward from there on Main Street to the University of Findlay and Trenton Avenue west. Trenton Avenue leads both to I-75 at Exit 159, where the business loop ends.
