The Blue, Yellow and Green Lines will be spared track work this weekend.
Scheduled track work will cause delays on Metro's Orange and Red Lines this weekend.
Starting at 10 p.m. tonight, shuttle buses will replace Red Line trains between Takoma and NoMa-Gallaudet while crews work on tracks, station platforms, and bridges. Metro says anyone headed through that stretch can expect it to take up to 40 minutes longer than it usually does.
On the Orange Line, meanwhile, trains will share a single track between East Falls Church and West Falls Church for work related to the Silver line extension. There will also be single-tracking between Stadium-Armory and Cheverly for track and platform work. Metro says Orange Line passengers should allow for about 15 minutes of additional travel time.
There's no scheduled work on the Blue, Yellow, or Green Lines.
One additional note: on Saturday morning the Metrorail system will open two hours early for the Rock 'n' Roll Marathon. That means stations will open at 5 a.m. instead of the usual 7 a.m. Saturday opening.
