Ohio State Route 368 is a short spur north to Seminole Island in Indian Lake, in Logan County. The southern end is at Ohio Route 366, east of Russells Point. From Ohio Route 366, Ohio Route 368 stems northward. It crosses a bridge onto Lake Ridge Island and Shawnee Island, where it bends westerly. That western bend crosses a bridge onto Seminole Island, where the route ends. Like most other highways numbered in the 360's, Ohio Route 368 serves recreational areas on a lake.
My photo of Ohio Route 368 shows the first northbound trailblazer, seen by those turning off of Ohio Route 366. This photo was taken at the only other route that Ohio Route 368 intersects, and it was taken on Leap Day 2016.
