Infrastructure improvements will begin September 2018 along the Dulles Toll Road. Improvements include a new toll collection system, which will replace an outdated 30-year-old system, as well as digital lane signage, enhanced violation camera technology and upgraded vehicle classification readers and antennas.

Drivers should be aware of lane closures over the next five months, as individual lanes close for construction. To minimize impacts to customers, lane closures will be limited to one land east-bound and one lane west-bound, and a minimum of two full service lanes will be maintained at the Mainline Toll Plaza at all times in each direction. Two full-time crews will be deployed, working flexible hours seven days per week, starting at opposite ends of the toll road. Motorists and media will receive updates via the Dulles Toll Road Facebook page, Twitter and the website throughout the project.

Construction Alerts and lane closures will be posted to the Dulles Toll Road website home page as new phases of construction begins. Visit our Construction Alerts to learn more about construction activity that could affect daily commutes east- and west-bound.
