When the US highway system was established, this road was labeled US route 50N, and later US route Alternate 50 (Alt50), eventually becoming US route 50A and then losing its Federal Highway status to become Ohio State route 550. The route ran from Athens, Ohio to Marietta, Ohio and thirty-two miles beyond to join with US route 50S now just plain US50. The route is scenic and offers some impressive views of the forested countryside in Southeastern Ohio. Seekers should park just to the East of the spot. Bring your own pen. Watch for traffic.
