FAIRFAX – A full closure of I-495 South (Capital Beltway Outer Loop) at I-66 is planned during the overnight hours tonight, Monday, December 6, and tomorrow night, Tuesday, December 7, for continued bridge beam installation at the I-66/I-495 Interchange. Traffic will be detoured around the closure via I-66 West and Nutley Street. The 495 Express Lanes South will also be closed, as will the ramp from I-66 West to I-495 South and several 495 Express Lanes ramps.  

Drivers traveling on I-66 and I-495 during this time should expect delays and consider using alternate routes. Message boards across the region will direct drivers on I-95 and I-495 to use alternate routes those nights.

Crews are installing beams for a new flyover ramp from I-495 North to I-66 West as part of the Transform 66 Outside the Beltway Project.

All work is weather dependent.  Wednesday, December 8, and Thursday, December 9, will be used as backup nights if inclement conditions occur.

Details include:

Monday, December 6, and Tuesday, December 7 (Wednesday, December 8, and Thursday, December 9, as necessary)
