[edit] Route History
State Route 15 was certified in 1926. It originally went 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 freeway with non-signalized at-grade intersections and ramps for otherwise signalized intersections 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.
Before 1926, the route number 15 was used for the current routing of the Ohio portion of U.S. Route 322.
