A shuttle will be running between the Pentagon and Rosslyn Metro stations this weekend.
Update, 11:55 a.m.: Metro has announced that all planned track work on Sunday has been cancelled, as the transit agency prepares for the expected Winter storm. Trains will operate on normal Sunday schedules.
Original Story: Buses will replace trains on part of Metro's Blue Line this weekend.
Scheduled track work gets underway at 10 p.m. tonight, and consequently, the Arlington Cemetery station will be closed all weekend. It will be served only by a special shuttle running from the Pentagon station. Free shuttle buses will also connect along the Blue Line between the Pentagon and Rosslyn.
Elsewhere around the system, passengers could face a longer wait on the station platform this weekend. Work along the Yellow and Green Lines will have trains operating once every 15 minutes, while on the Orange Line, trains will run once every 20 minutes.
And on the Red Line, trains will depart Shady Grove and Glenmont once every 20 minutes all weekend, although tomorrow and Sunday between 9 a.m. and 9 p.m., additional trains will make the wait more like every 10 minutes between Grosvenor and Silver Spring.
