Work at National Airport will affect Yellow and Blue Line riders this weekend

Metro’s Yellow and Blue lines will be closed between the Braddock Road and Reagan National Airport stations from Friday through Monday due to repair work.

Operations will affected the entirety of all four days, and Metro is warning riders that there may be crowding due to less frequent service.

On Friday and Monday, the Yellow Line will run between Huntington and Braddock Road every 12 minutes, and every 12-16 minutes between the Pentagon City and Mount Vernon Square stations. Blue Line trains will run every 12 minutes between Franconia-Springifield and Braddock Road, and between Pentagon City and Mount Vernon Square every 12-minutes.

Shuttle buses will run on Friday and Monday between Franconia-Springfield and Pentagon, and between Braddock Road and the Pentagon between 5 a.m. and 8 p.m.

On Saturday and Sunday, the Yellow Line will run between Huntington and Braddock Road every 12-15 minutes, and between Pentagon City and Mount Vernon Square every 24 minutes. The Blue Line will run between Franconia-Springfield and Braddock Road every 12-15 minutes during the day and between Pentagon City and Eastern Market every 24 minutes all day.

The work at Reagan will include the installation of new concrete pads beneath the rails on the elevated tracks near the station, as well upgrades to several switches outside the station, according to Metro.

A far more significant closing looms later this month. Work on the Yellow Line Bridge over the Potomac River is scheduled shutdown the line between Pentagon and L’Enfant Plaza for 14 days starting Nov. 26.
