B2 initially started off as a streetcar line in 1910, operating between
Mount Rainier, MD, Municipal Place &
Rhode Island Avenue & the
Anacostia neighborhood of
Southeast Washington D.C. The B2 streetcar line was later replaced by buses in 1923 and eventually became a Metrobus Route on February 4, 1973 when WMATA acquired four private bus companies that operated throughout the Washington D.C. Metropolitan Area and merged them all together to form its own, "Metrobus" System. Route B2 kept operating on the same exact routing as its streetcar route after. On December 28, 1991, when
Anacostia station opened, B2 was extended from its original
Anacostia terminus at the intersection of W Street SE & 16th Street SE, to operate to the new Anacostia station in the adjacent neighborhood of
Barry Farm in
Southeast Washington D.C. In 2001 when a roundabout was constructed at the intersection of
Rhode Island Avenue, 34th Street, & Perry Street in
Mount Rainier, MD to replace the original traffic lights at the intersection, B2 was rerouted to enter the roundabout when operating to both
Mount Rainier and the
Anacostia Metro Station. Since then, the B2 kept its current routing and has not gone through any changes. During the
COVID-19 pandemic, the line was reduced to operate on its Saturday supplemental schedule during the weekdays beginning on March 16, 2020. On March 18, 2020, the line was further reduced to operate on its Sunday schedule. On March 21, 2020, weekend service was reduced to operate every 30 minutes. Service was restored to its full service on August 23, 2020. In February 2021, WMATA proposed to reroute the B2 to replace portions of the B8, B9, D6, and H6 which would operate between Fort Lincoln and Union Station via Market Street NE, Fort Lincoln Drive, Eastern Avenue, Bladensburg Road, 14th/15th streets, C/D streets, Stanton Square and Massachusetts Avenue and eliminate service on Eastern Avenue NE (north of Bladensburg Road) and Rhode Island Avenue if WMATA does not get any federal funding. On September 5, 2021, the line was increased to operate every 20 minutes daily. The line was further increased to operate every 12 minutes on June 25, 2023.
Better Bus Redesign In 2022, WMATA launched its Better Bus Redesign project, which aimed to redesign the entire Metrobus Network and is the first full redesign of the agency's bus network in its history. In April 2023, WMATA launched its Draft Visionary Network. As part of the drafts, WMATA proposed to extend the B2 from Mount Rainier Terminal to operate to
West Hyattsville station via 38th Avenue and Hamilton Street as Route DC114. The proposed route would still operate between
Anacostia station and Mount Rainier Terminal, but was also changed to operate along 17th Street SE, 19th Street SE,
Stadium–Armory station, Potomac Avenue SE, 11th Street SE, and Martin Luther King Jr. Avenue. Service along 14th Street SE and 15th Street SE was replaced by the proposed Route DC219, which operated between Fort Lincoln and
L'Enfant Plaza station, while service along Minnesota Avenue SE, and W Street SE was replaced by the proposed Route DC117, which operates between
Navy Yard–Ballpark station and
Capitol Heights station. Service along Pennsylvania Avenue SE and East Capitol Street SE was replaced by other Metrobus Routes. During WMATA's Revised Draft Visionary Network, WMATA renamed the DC114 to Route C41, keeping its same routing between Anacostia station and Mount Rainier Terminal, and had every other trip terminate continue to West Hyattsville station. Route DC219 was renamed to Route D39 and would also keep its same routing, but was dropped during the proposals. The C41 changes were then proposed during WMATA's 2025 Proposed Network. During the proposals, Route C41 was changed again to have service restored along 14th Street SE, 15th Street SE, and East Capitol Street NE/SE, with the rest of the C41 routing being unchanged. On November 21, 2024, WMATA approved its Better Bus Redesign Network. As part of WMATA's Better Bus Redesign beginning on June 29, 2025, the B2 was modified to no longer have service along Pennsylvania Avenue SE, Minnesota Avenue SE, or operate along the Sousa Bridge. Instead, the B2 operates along 11th Street SE via the 11th Street Bridge from Anacostia before turning onto Potomac Avenue SE, before following the current B2 routing. Every other daytime and all late night trips was extended to
West Hyattsville station via 38th Avenue and Hamilton Street, partially replacing the former
F1. The line was renamed to the C41. ==Incidents==
