Orange, Silver and Blue line trains will run every 20 minutes. Orange Line trains will single-track between Stadium-Armory and Cheverly, and Blue Line trains will single-track between Braddock Road and Van Dorn Street
On the Yellow Line, trains will run every 20 minutes between Huntington and Mount Vernon Square only. Trains will single-track between Braddock Road and Huntington. Riders traveling to or from stations north of Mount Vernon Square should use the Green Line.
Green Line trains will run at regular weekend intervals Friday and Sunday. On Saturday, trains will run at regular weekend intervals between Greenbelt and Naylor Road, with only every other train traveling to Branch Avenue.
