The U Street–Garfield Line, designated Routes 90 and 92, are daily bus routes operated by the Washington Metropolitan Area Transit Authority between Anacostia station (90) or Congress Heights station (92) of the Green Line of the Washington Metro and Duke Ellington Bridge (90) in Adams Morgan or Reeves Center / U Street station (92) of the Green Line of the Washington Metro.

Route 90 operates along Howard Road and Martin Luther King Jr Avenue.

[4] Additional route 90 trips operate on school days from KIPP DC College Prep to Anacostia station leaving at 4:10 pm.

Additional weekday peak-hour route 92 trips operate between Congress Heights and Eastern Market station only in order to reduce crowding.

Route 93 was also shifted to the U Street–Garfield Line and being extended from Shipley Terrace to Congress Heights station alongside the 92.

Multiple passengers complained about the route being crowded, loud buses, buses behind schedule, low frequency, safety and security, shelters and stops, communication, and extending the western end of line up to Woodley Park station or McLean Gardens again.

In 2015, WMATA proposed to eliminate all route 93 service due to low ridership along Stanton, Pomeroy, and Morris Roads and to simplify the line.

[15] During the COVID-19 pandemic, routes 90 and 92 were reduced to operate on its Saturday supplemental schedule beginning on March 16, 2020.

[19] In 2020, WMATA proposed to eliminate the 92 short trips between Congress Heights and Eastern Market stations as there is alternative service on each stop and at the request of the District Department of Transportation.
