Expect delays on Metro this weekend as the transit agency uses the long holiday weekend to do track work.
Two stations, Federal Center SW and Capitol South, will close Friday at 10 p.m. on the Blue and Orange lines.
Shuttle buses will run between the L'Enfant Plaza and Eastern Market stations.
On the red line, trains will be single tracking between Dupont Circle and Friendship Heights as well as between Takoma and Forest Glen.
Trains should be back to normal schedules by Tuesday morning.
