Lane closures expected to last through the weekend, re-opening August 12

Beginning August 9 through August 12, construction will continue along the westbound Dulles Toll Road impacting Exit 9/Sully Road. As a result, two left lanes will be closed for multiple days and occasional traffic delays are expected.

During the closures, a full-service lane on the right will remain open westbound. 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.
