The Mon–Fayette Expressway is an interstate tolled freeway that is planned to eventually link Interstate 68 near Morgantown, West Virginia with Interstate 376 near Pittsburgh. The ultimate goal of the highway is to provide a high speed north-south connection between Morgantown and the eastern side of Pittsburgh while revitalizing the economically distressed towns in Fayette and Washington counties, serving as an alternative to Interstate 79 to the west, as well as relieving the PA 51 alignment from Pittsburgh to Uniontown. In addition, a second branch in Allegheny County will provide a bypass to the Squirrel Hill Tunnel.
