About the Project
This project will connect the Washington Boulevard on-ramp to the off-ramp at the Dulles Airport Access Road, creating a one-mile stretch of auxiliary lane to improve operations and safety on westbound I-66.
A new 12-foot-wide shoulder will also be constructed, with full-strength pavement capable of carrying traffic during emergencies.
A similar project was completed in December 2011, extending the acceleration lane at the Fairfax Drive on-ramp (just west of George Mason Drive) to the deceleration lane at the Sycamore Street off-ramp, creating a continuous auxiliary lane of almost two miles between the two ramps. A new 12-foot-wide shoulder was also constructed.
A third project between Lee Highway and Glebe Road is planned but not yet fully funded for construction.
No daytime traffic impacts are expected as crews will work behind barriers.
All lane closures will be done at night from 10 p.m. to 5 a.m.
Soundwall panel installation is ongoing. A more accurate projection as to the final completion of each wall will be available on this website in the near future.
Notification of future paving operations will be posted on this website.
