From 10:00 p.m. Friday to the end of the day on Sunday, the Blue and Orange Lines will be effectively split in two segments. No trains will run between Foggy Bottom and Arlington to “allow for rail fastener renewal, insulator replacement and sludge removal from the tunnel beneath the Potomac River.”
Shuttle buses will run between the Foggy Bottom, Rosslyn and Courthouse stations and from the Foggy Bottom, Rosslyn, Arlington Cemetery and Pentagon stations.
