The eastbound lanes of Tysons Boulevard are scheduled to close tonight between Chain Bridge Road (Route 123) and Galleria Drive in Tysons Corner. They will close again on Friday and Saturday nights.

The closings will clear work zones for the Dulles Metrorail project. Crews will be working on the bridge and piers near the future Tysons Central 123 station.

This also will require the closing of the turn lanes onto eastbound Tysons Boulevard from northbound Chain Bridge Road and from Galleria Drive.

Project officials say the lane closings will begin about 9:30 p.m., and will be lifted by 5 o’clock the following morning.

Detours will be in marked.
