Ohio State Route 748 pokes southwesterly out of Millville to end in the small hamlet of Shandon, in southwestern Butler County. The northern beginning of Ohio Route 748 is at Ohio Route 129 in Millville, about five miles west of Hamilton. The route extends only 6 miles southwesterly from there. The southern end, at the aforementioned hamlet of Shandon, is at Ohio Route 126.
My photo for Ohio Route 748 signage comes from the northern end at Ohio Route 129 in Millville. Travelers leaving Millville toward the west will see this sign along Ohio Route 129, indicating that this left turn is the turn onto Ohio Route 748. This photo was taken on the way home from the tour around southwestern Ohio in October 2018.
