Two-Way Traffic Will Travel in Single Lane on I-66 West at Route 50 in Fairfax During Overnight Hours Feb. 16-18 for Bridge Beam Installation
Lane closures, traffic stoppages on Route 50 planned nightly

UPDATE (2/16/2021): This work has been rescheduled to Thursday night, February 18, and Friday night, February 19. It has been cancelled for tonight (Tuesday, February 16) and Wednesday, February 17.

FAIRFAX – I-66 East and West approaching Route 50 in Fairfax will be reduced to a single travel lane in each direction for about one mile during the overnight hours next week as bridge beam installation continues at the I-66/Route 50 Interchange. Two-way traffic will run on I-66 West so that crews can safely install bridge beams over the eastbound lanes of I-66. The Route 50 Interchange is being rebuilt as part of the Transform 66 Outside the Beltway Project.

Route 50 East at I-66 will be reduced to a single travel lane with traffic stoppages each night as well, and multiple ramps will be closed nightly at the interchange. Drivers traveling on I-66 and Route 50 East during this time should expect delays and should consider using alternate routes. 

All work is weather dependent and will be rescheduled if inclement conditions occur.

Details include:

Tuesday, February 16, through Thursday, February 18

  • Around 10 p.m. I-66 West traffic approaching Waples Mill Road will be narrowed to a single right lane and remain on the right side of the interstate beyond Monument Drive. Westbound traffic will resume normal travel following the point where eastbound traffic crosses on to the westbound lanes.
