I'm leaving this alone. OH 47 E does follow Mad River, but OH 47 Wstill follows US 68 along Main St. If not for both directions of US 68 following only Main St, I would move 47 to the midpoint between Main & Mad River, but that would break the concurrency with US 68, and I think travellers going south on Main should get credit for OH 47 between Rush Ave & Sandusky Ave.
