FAIRFAX – All lanes of I-66 West approaching I-495 will be closed during the overnight hours Friday and Saturday, April 9 and 10, to allow for installation of bridge beams for new ramps at the I-66/I-495 Interchange. All I-66 West traffic will be detoured around the closure via Route 7 (Leesburg Pike) West and I-495 South. The I-66/I-495 Interchange is being rebuilt as part of the Transform 66 Outside the Beltway Project.

The ramps from I-495 North to I-66 West, and from the 495 Express Lanes South to I-66 West will also need to be closed during these overnight hours. Detour routes will be posted.

Drivers traveling on I-66 and I-495 during this time should expect delays and should consider using alternate routes.
