Ohio State Route 101 runs northeast out of Tiffin to Sandusky, in north-central Ohio. Both of the highway's endpoints are met while the highway is part of a concurrency. The southwestern end is concurrent with Ohio Route 18, which follows a pair of one-way streets in Tiffin. A pair of intersections along Ohio Route 53 and US Route 224 give way to the western start of Ohio Route 101, which turns northeasterly off of Ohio Route 101 in the center of Tiffin. At the other end, Ohio Route 101 ends concurrently with US Route 6, at an intersection in downtown Sandusky that's also the northern end of Ohio Route 4. Between its two endpoints, Ohio Route 101 serves Clyde, where it meets Ohio Route 510 and US Route 20, and Castalia, where it meets Ohio Route 269.
My photo of Ohio Route 101 signage comes from Clyde, where it gives a southern beginning to Ohio Route 510. When just a few blocks south of US Route 20, Ohio Route 101 bends from a northerly route to a northeasterly route, but the northerly road continues as the first piece of Ohio Route 101. This photo looks north at Ohio Route 101's bend to the right; the pavement continuing into the background is the start of Ohio Route 510. I took this photo in October 2023, as I was finishing my shield gallery of Ohio in the northwestern portion of the state.
