Appalachian Corridors The interstates are supplemented by roads constructed under the Appalachian Corridor system. Four Corridors are complete. Corridor D, carrying US 50, runs from the Ohio River, and I-77, at Parkersburg to I-79 at Clarksburg. Corridor G, carrying US 119, runs from Charleston to the Kentucky border at Williamson. Corridor L, carrying US 19, runs from the Turnpike at Beckley to I-79 near Sutton (and provides a short cut of about and bypasses Charleston's urban traffic for travelers heading to and from Florida). Corridor Q, carrying US 460, runs through Mercer County, entering the state from Giles County, Virginia and then reentering Virginia at Tazewell County.
