Single-lane, overnight closures will continue on I-66 inside the Beltway through the end of March, according to VDOT.

Crews are completing survey and “geotechnical investigation work” related to the I-66 eastbound widening project.

The single lane closures are scheduled for between 9:30 p.m. and 5 a.m. nightly between I-495 and Fairfax Drive (Route 237). Shoulder closures are intermittently planned from 12 p.m. to 3 p.m., weather permitting.

Real-time traffic information and lane and shoulder closure locations are available online.

More from the Virginia Department of Transportation press release:

The survey and geotechnical investigation work is needed prior to the start of construction that will add an additional through lane along four miles of eastbound I-66 between the Dulles Connector Road (Route 267) and Fairfax Drive (Exit 71) in Fairfax and Arlington counties. Other key project features include constructing a new bridge over Lee Highway for the Washington & Old Dominion (W&OD) Trail and providing direct access from eastbound I-66 to the West Falls Church Metro station by constructing a new ramp connection between two existing ramps (eastbound I-66 to Route 7 and the eastbound I-66 collector-distributor road adjacent to the station’s parking garage).
The additional lane will be open to traffic in fall 2020 and the overall project is expected to be complete in fall 2021.

Separately, VDOT has also announced additional overnight lane closures on Route 110 near the Pentagon.

On Monday night, Feb. 12 and Tuesday night, Feb. 13 between 10 p.m. and 5 a.m. each night, the northbound right lane of Route 110 at the Route 27 interchange and then the southbound right lane of Route 110 will be closed to allow crews to demolish and rebuild bridge piers, according to the Virginia Department of Transportation.

The closures will remain in place for approximately two months.

The work is part of the Route 27 over Route 110 project, which is scheduled for completion this summer.
