Two-way traffic will travel in a single lane on I-66 west at Route 50

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. Work is weather dependent and could extend to the weekend if there is inclement weather. 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 ramp closures will be implemented at the interchange. Drivers traveling on I-66 during this time should expect delays and should consider using alternate routes.

Depending upon the forecasted winter storm, this work may be rescheduled.

Details include:

Sunday, January 31, and Monday, February 1
Wednesday, February 3, through Sunday, February 7 (as needed)
