 The highway serves Charleston, the capital and largest city in West Virginia; it also serves the cities of Princeton, Beckley and Parkersburg.I-77 uses the entire length of the West Virginia Turnpike, a toll road between Princeton and Charleston, and it runs concurrently with I-64 between Beckley and Charleston.Historically, the West Virginia Turnpike was a two-lane road with treacherous curves and a tunnel (which has since been decommissioned).
