It crosses the harbor of Hampton Roads at two locations on large four-laned bridge-tunnel facilities: the eastern half carries Interstate 64 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 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.

A directional interchange, colloquially known as a stack interchange, is a type of grade-separated junction between two controlled-access highways that allows for free-flowing movement to and from all directions of traffic. These interchanges eliminate the problems of weaving, have the highest vehicle capacity, and vehicles travel shorter distances when compared to different types of interchanges.
Interstate 95 (I-95) runs 179 miles (288 km) within the commonwealth of Virginia between its borders with North Carolina and Maryland. I-95 meets the northern terminus of I-85 in Petersburg and is concurrent with I-64 for three miles (4.8 km) in Richmond. Although I-95 was originally planned as a highway through Washington, D.C., it was rerouted along the eastern portion of the Capital Beltway concurrent with I-495. From Petersburg to Richmond, I-95 utilized most of the Richmond–Petersburg Turnpike, a former toll road. In addition to Richmond, the route also runs through the medium-sized cities of Emporia, Petersburg, Colonial Heights, Fredericksburg, and Alexandria.

Virginia HOT lanes refers to six separate projects in the U.S. state of Virginia. The first project, completed in November 2012, added high-occupancy/toll (HO/T) lanes to the Capital Beltway (I-495) in Fairfax County. The second project, opened to the public in December 2014, involved converting and extending the existing reversible high-occupancy vehicle (HOV) lanes on I-95 and a portion of I-395 to HO/T lanes from Stafford to near Alexandria. The third project converted all lanes on I-66 inside the Beltway to peak-direction HO/T lanes, opening on December 4, 2017. The fourth project reconstructed approximately 21 miles (34 km) of I-66 outside the Beltway, making it a 10-lane corridor. The fifth project, which was completed in November 2019, essentially extended the aforementioned I-95/I-395 project several miles to the north, converting the existing reversible 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 HO/T Lanes on Interstate 64 from Interstate 564 in Norfolk to Interstate 264 in Virginia Beach, and also propose to expand the I-64 express lanes before and after the HO/T Lanes. The seventh project, which is be completed by Spring 2024, extended I-95's HO/T lanes from VA 610 in Garrisonville to its northernmost interchange with US 17 and US 17 business in Falmouth. The eighth project, which is expected to be completed by 2026, will extend the Capital Beltway's (I-495) HO/T lanes two miles north from VA 267 in Tysons to the American Legion Memorial Bridge.
