Interstate 77 (I-77) in the US state of Virginia is a 67-mile (108 km) north–south Interstate Highway serving Hillsville, Wytheville, and Bland. Running parallel to US Route 52 (US 52), I-77 passes through the Big Walker Mountain Tunnel and East River Mountain Tunnel, the latter on the West Virginia state line and one of only two land vehicular tunnels to cross a state line. It is planned to overlap with the proposed I-74 in the future.
