State Route 15 is a north–south/east–west route in northwestern Ohio. Its southern (eastern) terminus is at its interchange with U.S. Route 23/State Route 103 near Carey, and its northern (western) terminus is at the Michigan state line north of Pioneer, where the route continues in Michigan as M-99. The route is bannered east–west from Carey to Bryan, and is bannered north–south from there to the Michigan state line.

State Route 15 is an expressway for its southeasternmost 19 miles: 2 miles as a concurrency with Interstate 75, 3 miles as a concurrency with U.S. Route 68, and the final 14 miles as a stand-alone freeway until its junction with U.S. Route 23. The final 17 miles are part of a heavily traveled corridor providing the most direct route between Detroit, Toledo, Findlay, Marion and Columbus.

Route History

State Route 15 was certified in 1923, along the current U.S. Route 322, which replaced it in 1926.

In 1926 the designation was reapplied to a route from Carey to the Indiana state line. In 1929 it was rerouted to Bryan, replacing parts of State Route 9. It replaced the rest of State Route 9 in 1931, rerouted along its current route to the Michigan state line.

In 1966, State Route 15 was rerouted on a expressway from Interstate 75 in Findlay to U.S. Route 23 in Carey, its new southern (eastern) terminus. The highway runs a few miles south of its previous routing, which was recertified as State Route 568 the same year.
