The rule
Bicycles are prohibited on Interstate highways in Ohio. Ohio Rev. Code § 4511.051 prohibits bicycles, pedestrians, and other non-motorized traffic on freeways. The Ohio Department of Transportation enforces the prohibition statewide; cyclists must route on US, state and county routes paralleling the Interstate corridor.
What this means in practice
Stick to surface streets, US routes, state highways, and dedicated paths. If your route in Ohio appears to use an Interstate, plan a detour before you start.
