From WMATA:
“Metro is reminding Red Line customers to plan ahead for the last two weeks of December. On Monday, December 18, our team will begin a two-week construction project on the Red Line to perform critical safety repairs to the tunnel and track infrastructure, upgrade signal and communications systems, and install new platform edge lights.
To complete the work safely and efficiently, there will be no Red Line service between Dupont Circle and Gallery Place from Monday, Dec. 18 through Saturday, Dec. 30.
Farragut North will be closed, and no Red Line service will be available at Metro Center (upper level). Normal service will operate on all other lines serving 97 of Metro’s 98 rail stations.
Trains on the Blue, Orange, and Silver lines will continue to provide service to Metro Center. Customers will be able to access the station at both entrances on 12th Street NW, while the entrances on G Street NW at 11th and 13th streets will be closed to accommodate equipment and work crews.
Customers traveling to Gallery Place will be able to use the Red Line from Glenmont. The Yellow and Green lines will provide normal service.
During construction only Farragut North will be closed for the entire duration of the project and frequent shuttle buses will run to every station affected.”
