Hampton Roads Beltway: The Hampton Roads Beltway is a loop of Interstate 64 and Interstate 664, which links the communities of the Virginia Peninsula and South Hampton Roads which surround the body of water known as Hampton Roads and comprise much of the region of the same name in the southeastern portion of Virginia in the United States.  It crosses the harbor of Hampton Roads at two locations on large four-laned bridge-tunnel facilities: the eastern half carries Interstate 64 (and U.S. Route 60) and uses the Hampton Roads Bridge-Tunnel and the western half carries Interstate 664 and uses the Monitor-Merrimac Memorial Bridge-Tunnel.  The beltway has the clockwise direction (as looking down at a map of the area) signed as the Inner Loop, and the counter-clockwise direction signed as the Outer Loop.  The entire beltway, including the bridge-tunnels, is owned and operated by the Virginia Department of Transportation.

The third project, currently under construction (as of December 2016), will convert the existing high-occupancy vehicle (HOV) lanes inside the beltway on Interstate 66 to HO/T lanes.  The fourth project will convert the existing high-occupancy vehicle (HOV) lane outside the beltway on Interstate 66 and add a second lane to HO/T lanes.  The fifth project will convert the existing reversible high-occupancy vehicle (HOV) lanes on I-395 to HO/T lanes from near Alexandria to Washington, DC.  The sixth project will convert the existing reversible HOV Lanes to HOT Lanes on Interstate 64 from Interstate 564 in Norfolk to Interstate 264 in Virginia Beach.
