Route D1 was created as a new route in 1999 under the
Sibley Hospital–Stadium Armory Line operating alongside the D3, and D6 as a weekday peak-hour supplement service to route D2. The new route D1 operated between
Glover Park and
Washington Union Station via
Federal Triangle and
Franklin Square mostly operating along Q Street NW,
K Street NW, E Street NW, and 13th Street NW. The line would connect the growing
Georgetown and residents in
Glover Park and
Burleith to
Downtown as there were no Metrorail station that was built in Georgetown. On December 27, 2009, route D1 was shortened to
Federal Triangle with service to
Washington Union Station being replaced by routes D3 during the weekday peak-hours. It was also split from the
Sibley Hospital–Stadium Armory Line and operated on its own as the
Glover Park–Franklin Square Line. According to WMATA, it says:
The route will be changed to operate between Glover Park and Federal Triangle. Eastbound buses will follow the regular route from Glover Park to 13th and E Streets, NW, then continue via 13th Street onto Pennsylvania Avenue to the terminal stand on the west side of 10th Street, NW. The westbound route will begin at this terminal stand and continue via Constitution Avenue, 12th Street, Pennsylvania Avenue, 13th Street and resume the regular route. Two new buses will be scheduled to leave eastbound from Glover Park at 9:05 a.m. and westbound from Federal Triangle at 7:05 p.m. The bus schedule will change. In 2015, WMATA proposed to eliminate the D1 segment between
Franklin Square and
Federal Triangle as the portion suffers from low ridership. Alternative service is provided by routes
42, 80,
D6, S2, S4, and
X2. On June 26, 2016, route D1 was shortened even further from
Federal Triangle to
Franklin Square due to low ridership. In 2019, WMATA proposed to eliminate the D1 and replace it with a proposed G2 reroute due to alternative service available. The proposal was met with controversy with residents due to service being lacking in
Georgetown if the proposal goes through. WMATA later backed out of the proposal due to major customer opposition. In response to the
COVID-19 pandemic, WMATA suspended all D1 service on March 16, 2020. The proposed elimination was brought back up on September 26, 2020 due to low federal funding. Route D1 has not operated since March 13, 2020 due to Metro's response to the
COVID-19 pandemic. The proposal went through and by September 5, 2021, Route D1 was no more. ==References==
