Starting at 10 p.m. Friday, there will be no Green Line service at L'Enfant Plaza, and the Waterfront station will close. Buses will be shuttling Green Line passengers between the Archives and Navy Yard stations, and Metro says anyone headed through that stretch should add 10 minutes of travel time for each stop they'll be making.
Meanwhile, there will be no Yellow Line service this weekend while crews perform an annual inspection of the Yellow Line bridge. A special shuttle train will run once every 10 minutes between Huntington and Braddock Road, where passengers will need to transfer to a Blue Line train.
There's no work planned on the Blue Line, but on the Orange Line, trains will run once every 20 minutes all weekend. On the Red Line, trains will run once every 16 minutes with extra trains making that more like 8 to 10 minutes between Farragut North and Silver Spring from 9 a.m. to 9 p.m. Saturday and Sunday.
