Ohio 550 — Pioneer Pass
Ohio State Route 550 stretches 40.58 miles east–west across Athens and Washington counties, tracing the original Marietta–Chillicothe Stagecoach Road corridor between US-33 north of Athens and SR-7 west of Marietta. The Windy 9 maps it as Route 6: Pioneer Pass (103.5-mile loop out of Athens, combining SR-550 with SR-329). The road flows through miles of rural Ohio farmland along ridge lines and creek drainages, with moderate curves and light traffic. It serves as a natural connector between the Athens Windy 9 hub and Marietta, pairing well with the adjacent OH-26 Covered Bridge Byway (which begins at Marietta) for a full SE Ohio day loop. Communities along the route include Amesville, Guysville, and Bartlett.
