Tysons lane shift planned for Thursday night

The Dulles Metrorail project has moved up a scheduled lane shift on Route 7 in Tysons Corner by one night. The work now is scheduled to start Thursday instead of Friday.

Drivers on this portion of Route 7 (Leesburg Pike) have grown familiar with the lane shifts required to bring the new line through a short tunnel and out to the median of Route 7, where two stations also will be built. This lane shift will affect travel on the westbound side of the roadway, in the direction of the Dulles Toll Road.

According to the latest schedule, workers will be moving the westbound lanes between Route 123 and Westpark Drive slightly north to allow construction of the west end of the tunnel from Route 123.

The lane shift is scheduled to start at 10:30 p.m. Thursday. This will require closing the right and center through lanes on Route 7. Only the left lane will remain open. At about 2 a.m. Friday, the left and center lanes will close and traffic will be directed to use the newly opened right lane.

All work is scheduled to be done by 7 a.m. Friday. But if bad weather forces a postponement, the lane shifts will be rescheduled for Friday night, as originally planned.
