Interstate 64 (I-64) in the US state of Virginia runs east–west through the middle of the state from West Virginia to the Hampton Roads region, for a total of 299 miles (481 km). It is notable for crossing the mouth of the harbor of Hampton Roads on the Hampton Roads Bridge–Tunnel (HRBT), the first bridge–tunnel to incorporate artificial islands, concurrent with U.S. Route 60 (US 60). Also noteworthy is a section through Rockfish Gap, a wind gap in the Blue Ridge Mountains, which was equipped with an innovative system of airport-style runway lighting embedded into the pavement to aid motorists during periods of poor visibility due to fog or other conditions.
