Scheduled maintenance work is causing delays on Metrorail on this Martin Luther King Jr. holiday.
Metro says the work is going well and proceeding as scheduled. Still, the Foggy Bottom station on the blue and orange lines will remain closed all day as the transit agency takes advantage of the federal holiday to replace four rail switches. Shuttle buses are running from Foggy Bottom to Farragut West and Rosslyn.
Meanwhile, other scheduled work is causing delays around the system, with trains sharing a single track between Braddock Road and Van Dorn Street on the blue line due to work on the Wilson Bridge project.
Construction on the Metrorail extension to Dulles Airport is causing single tracking on the orange line between West Falls Church and East Falls Church.
And work on the red line has trains sharing a single track between Rhode Island Avenue and New York Avenue and between the Friendship Heights and Van Ness stations.
Service is expected to be back to normal before Tuesday morning.
