All lanes on the Maryland side of Interstate 495 at the Woodrow Wilson Bridge will close tonight and Saturday for continuing work on the Route 210 Interchange.

At 11 p.m. tonight, the Inner Loop and Outer Loop of the Capital Beltway are slated to be closed so that contractors can lift steel beams into place for the 210 overpass. The work could last until 8 a.m. Saturday. The road is scheduled to be shuttered again Saturday at 10 p.m. for the same work, remaining closed until as late as 8 a.m. Sunday.
