Seven Red Line Metro stations will be affected by scheduled track work this weekend, with buses replacing trains on a portion of the line.
Metro says the work begins at 10 p.m. Friday night, and continues through Sunday. The Red Line will operate in two sections -- from Shady Grove to Dupont Circle, and from Glenmont to NoMa-Gallaudet.
Passengers will not be able to take the Red Line from Dupont Circle to NoMa-Gallaudet; instead, they'll have to take a free shuttle bus. Riders should add an extra 30 to 50 minutes to their travel time, depending if they're using an express or a local bus.
In addition, trains will single-track on a portion of the Yellow and Blue Lines, which will cause 10 to 15 minute delays.
