Work on the Yellow Line bridge will cut off the Yellow Line at Pentagon.
Those planning to travel on the Metro should tack on some extra time, as scheduled track work will cause delays on Metro this weekend.
Starting at 10 p.m. Friday night, there will be no Yellow Line service north of the Pentagon station due to weekend work on the Yellow Line bridge over the Potomac. Anyone who would normally be taking the Yellow Line into or out of the District will have to switch to a Blue Line train instead. On the northern end of the Yellow Line, passengers will have to take a Green Line train instead.
There will be delays on the Green Line as well though, with free shuttle buses replacing trains all weekend between the Archives and Waterfront stations while crews replace switches near L'Enfant Plaza. Metro it will take up to 20 minutes longer than usual to get through that stretch.
And on the Red Line, scheduled work will have trains sharing a single track along two stretches: between Friendship Heights and Van Ness and then again between Takoma and Forest Glen.
