Interchanges

Virginia/DC line

Note: The Independence Avenue and E Street exits are in the opposite order going westbound.

Spur Routes

None, although Interstate 266 was planned in northern Virginia and Washington, D.C. It was cancelled due to environmental concerns.

Extension projects

The U.S. Department of Transportation has had plans to extend I-66 westward across the country to California. Highway mavens have speculated as to where I-66 would go, such as the Corridor H Freeway in West Virginia and United States Highway 400 in Kansas.

Former Governor Paul Patton has written I-66 into law in Kentucky, with the routing being confirmed along the state's Hal Rogers Parkway (formerly Daniel Boone Parkway) and Louie B. Nunn Parkway (formerly Cumberland Parkway). Preliminary construction has started on a segment in Pulaski County.

Notes

  • Because of that heavy traffic, I-66 has HOV lanes. Between Route 234 in Manassas, Virginia and the Beltway, the left lane on eastbound I-66 is reserved for HOV-2 during morning rush hour, and the left lane on westbound I-66 is reserved for HOV-2 during evening rush hour. Between the Beltway and the Theodore Roosevelt Bridge, the entire eastbound roadway is reserved for HOV-2 and Dulles Airport traffic during morning rush hour, and the entire westbound roadway is reserved for HOV-2 and Dulles Airport traffic during evening rush hour.
  • This is the only 2 digit Interstate to enter the District of Columbia (other than the 100 yards (91 m) or so that I-95 passes through DC on the Woodrow Wilson Bridge). I-66 was planned to intersect I-95, before I-95 was rerouted to the east side of the Capital Beltway.
