The Metro Silver Line project is very active right now in the Tysons Corner area, and it’s going to have a greater impact on the local roadways next week.

This work is scheduled to continue through the end of May. Here’s the schedule.

Eastbound Route 267

Three right lanes at Route 7 and the ramp from eastbound Route 7 to eastbound Route 267 will close this Sunday through next Friday from 9 p.m. to 5 a.m. each night. They will also be closed April 22-24 during the same hours.

Three left lanes will close April 25-27, from 9 p.m. to 5 a.m. each night, and then during the same hours on April 29 and April 30.

A complete closing of the eastbound lanes of the toll road and the right-most lane of the access highway is scheduled for the nights of May 1-3.

Detour: Traffic will funnel into a single lane and then head onto the eastbound access highway just west of Route 7. Then drivers will continue east to the Capital Beltway or Interstate 66.

Toll Road drivers heading to westbound Route 7 or Spring Hill Road will need to exit onto eastbound Route 7.

No Route 267 eastbound traffic will be allowed to travel past eastbound Route 7.

There will be more lane closings along the access highway in May, but for now, let’s just review some of the other more immediate activity on the rail project in the Tysons area.

Route 7

The left through lane of Route 7 near Marshalls Drive is scheduled to close from 9 p.m. to 5 a.m. tonight and Friday. This clears the way for workers to install concrete panels at what’s now known as the Tysons Central 7 station. Other overnight closings of this lane are likely through the end of next week.

Tysons Boulevard

Tysons Boulevard will be closed between Chain Bridge Road (Route 123) and Galleria Drive overnights Friday and Saturday so crews can work on the rail bridge, piers and what’s now known as the Tysons Central 123 station.

The turn lanes onto Tysons Boulevard from Chain Bridge Road and from Galleria Drive also will be closed. The lane closings should start at 11 p.m. and continue to about 9 5 a.m. (Project officials sent out a statement Friday adjusting the time).

Pile driving

Pile driving will continue at the Tysons Central 7 station’s north pavilion near Westpark Drive/Gosnell Road between 7 a.m. and 9 p.m. through Saturday. The pavilions are the entryways to the pedestrian bridges leading into the stations.
