Ohio State Route 366 runs around the southern and western sides of Indian Lake, in Logan County. The state highway running around the north side of Indian Lake is an easterly jog in Ohio Route 235, which is a departure from its normally northward course. That east-west jog extends slightly west of Indian Lake's northern shore, to form an intersection with US Route 33. That intersection is where Ohio Route 366 begins, and it heads east to join Ohio Route 235 along the western shore of the lake. At the southwest corner of the lake, you'll find the town of Lakeview, where Ohio Route 235 departs and Ohio Route 366 bends eastward around the south side of Indian Lake. Ohio Route 366 passes through Russells Point, and it meets Ohio Route 368 at the southeast corner of the lake. But Ohio Route 366 isn't quite done yet; it continues eastward for a few more miles until it ends at Ohio Route 117 north of Huntsville.
My photo of Ohio Route 366 comes from the intersection with the minuscule, infinitesimal Ohio Route 365, north of Lakeview. The photo on the Ohio Route 365 page shows this pair of trailblazers in the background; both photos were taken at the same junction. Travelers moving northward beyond Ohio Route 365 will see this pair of trailblazers, reaffirming that they are following both Ohio Route 235 and Ohio Route 366. This photo was taken on Leap Day 2016 during a drive home from Columbus.
