Drivers can expect multiple lane closures along westbound I-66 from Lee Highway (East Falls Church) to the Dulles Airport Access Road ramp between 10 p.m. Thursday, May 14 and 5 a.m. Friday, May 15.
According to the Virginia Department of Transportation, two lanes of traffic will be maintained while the traffic is shifted to the newly built left lanes from Great Falls Street to the Dulles Airport Access Road. The partial traffic switch is part of a $33 million project to improve westbound I-66 inside the Beltway by connecting the Washington Boulevard on-ramp to the off-ramp at the Dulles Airport Access Road, creating a new one-mile stretch of auxiliary lane. A new 12-foot shoulder will have full-strength pavement capable of carrying traffic during emergencies.
The project is expected to be complete in August.
