Interstate 81 in Middletown, Virginia

Spur Routes None, although I-266 was planned in Washington, D.C., but was cancelled. It was cancelled due to environmental causes.

Notes This is the only 2 digit Interstate to enter DC (unless you count the 100 yards or so that I-95 crosses over the DC section of the Potomac). I-66 used to intersect I-95, before they rerouted I-95 to be the east side of the Capitol Beltway.

The Department of Transportation has 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.

President George W. Bush has written I-66 into law in Kentucky, with the routing being confirmed along the state's Daniel Boone and Cumberland (Louie B. Nunn) Parkways.
