Major Blue and Yellow Line Construction

Major blue and yellow line construction



The Yellow Line is now open! We appreciate your patience during this critical tunnel and bridge repair work!

Please note that the Yellow Line will operate between Huntington to Mt. Vernon Sq. only. To travel between Mt. Vernon Sq. and Greenbelt, please use the Green Line.

Metro's Major Blue Line and Yellow Line Construction team rehabilitated the Yellow Line tunnel and bridge between Pentagon and L'Enfant Plaza stations and connected the new Potomac Yard Station to the mainline rail system. This work required the Yellow Line tunnel near L'Enfant Plaza Station and the bridge across the Potomac River to close for approximately eight months. The Yellow Line tunnel and bridge structures date back to Metro's original construction and were nearing the end of their useful life expectancy. This rehabilitation work was necessary to ensure that both structures continue to function safely for years to come. The Yellow Line reopened on Sunday May 7th!

Sept. 10 - Nov. 5, 2022: No Metrorail service south of Ronald Reagan Washington National Airport Station as crews build new tracks that "tie in" the new Potomac Yard Station with the existing Metrorail system. There will be no Yellow Line service, but Yellow Line stations north of Reagan National Airport will be accessible via the Blue or Green lines.

Sept. 10, 2022 - May 2023: No Metrorail service between Pentagon and L'Enfant Plaza stations as crews work on the Yellow Line tunnel and bridge rehabilitation. Yellow Line stations will be served by the Blue or Green lines.

Fall 2022: Rail service will resume south of Reagan National Airport on November 6, and no stations will be closed. Potomac Yard Station will open in early 2023.

May 2023: Yellow Line tunnel and bridge improvements completed and Yellow Line service resumes.
