Four Metro stations will close down for the weekend starting late Friday night.
The Rhode Island Avenue, Brookland and Fort Totten stations on the Red Line and the Reagan National Airport station on the Blue and Yellow Lines will all close starting at 10 p.m. Friday due to weekend maintenance.
On the Red Line, buses will replace trains between NoMa-Gallaudet and Takoma. Free shuttles will also run between Crystal City and Braddock Road on the Blue and Yellow Lines.
Orange Line trains will also once again single track between East and West Falls Church.
All of this weekend's work is scheduled to wrap up by the time the system closes Sunday night.
