Lane closures expected to last through the summer; two full-service and three E-ZPass lanes remain open

Beginning on Wednesday, July 17, construction will continue along the eastbound Dulles Toll Road impacting the Main Toll Plaza. As a result, two center lanes will be closed for several consecutive weeks and occasional traffic congestion is expected.

During the closures, two full-service lanes on the right, two E-ZPass lanes on the left and one E-ZPass lane on the right will remain open eastbound. Please see below for more detailed information.

Customers should follow new directional signage and be prepared for delays during high-volume travel times. All work is weather dependent and subject to change.

To mitigate the traffic impacts, motorists are encouraged to:
