EAST RIVER MOUNTAIN TUNNEL

The East River Mountain Tunnel is a 5,142-foot vehicular tunnel that carries Interstate 77 and U.S. Route 52 through East River Mountain between the communities of Bluefield, West Virginia and Rocky Gap, Virginia. The East River Mountain Tunnel is one of only two land vehicular tunnels in the United States that cross a state line, the other being the Cumberland Gap Tunnel (Kentucky and Tennessee). The state line falls almost exactly across the midpoint of the tunnel, with 51% of the tunnel residing in West Virginia and the remaining 49% on the Virginia side.
