FAIRFAX – A full closure of I-495 South (Capital Beltway Outer Loop) at I-66 is planned during the overnight hours Friday, October 8, through Sunday, October 10, 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.
