Metro's scheduled track work continues this weekend, however the Green and Yellow Lines will be spared this week. Navy Yard station on the Yellow and Green Lines will be closed at 10 p.m. Saturday night though, for a security drill.
Maintenance and major delays will continue on all other lines.
On the Orange Line, buses are replacing trains all weekend between East Falls Church and West Church while crews install cables related to the Metro extension to Dulles airport. Passengers headed that way can expect it to take up to 20 minutes longer than usual.
On the Blue Line, trains are sharing a single track between Stadium Armory and Addison Road for work on the concrete slabs beneath the rails.
And maintenance on the Red Line has trains single tracking in two areas: between Grosvenor and Medical Center, and then again between Judiciary Square and Rhode Island Avenue.
The maintenance is part of Metro's six-year, $5 billion capital improvement program. Service should be back to normal Monday morning.
