List of Metrobus routes in Washington, D.C.

This is a list of bus routes operated by the Washington Metropolitan Area Transit Authority (WMATA), branded as Metrobus in Washington, D.C. Many are the descendants of streetcar lines operated by the Capital Transit Company or its predecessors.

Numbering

Most Metrobus routes in DC were formerly with a letter followed by a number but some routes can have double-digit numbers.^[1][2] Historically, the pattern was that:

• Double-digit numerical routes indicated former interurban streetcar lines. (70, 54, 43, etc.)
• Letter-number indicated routes primarily servicing DC. (S9, X2, H4, etc.)
• Letter-number-number indicated routes primarily servicing Maryland. (F14 T18, etc.)
• Number-letter indicated routes primarily servicing Virginia. (7A, 5A, etc.)

Odd-numbered routes are typically part-time variants of even-numbered routes. At one time, odd-numbered routes were express routes, but that distinction has been abandoned. Most odd-numbered routes operate during rush hours and or limited stops with a few of them running into the off-peak hours and weekends.

As of WMATA's Better Bus Redesign beginning on June 29, 2025, all DC routes start with a D or C designation, which applies to Downtown or Crosstown routes respectively, followed by two digits. The second digit identifies the corridor or neighborhood served, generally following a counterclockwise pattern in the style of the old streetcars. For example, the D10 follows Pennsylvania Avenue SE to Southern Avenue SE, and the D90 follows Massachusetts Avenue NW to Tenleytown. The third digit is simply a means of distinction between routes in one corridor; routes ending with X indicate express service.

History

Many current routes operate under former streetcar routes. The streetcars provided the main transportation in the Washington, D.C. area from the 1800s to the 1960s.^[3] DC Transit would also operate on the former streetcar routes when the Streetcars ended service. In 1973, WMATA acquired DC Transit along with other bus companies to form its current Metrobus system.^[4]

Due to the COVID-19 pandemic, service was mostly reduced to Sunday service schedules during the weekdays with select routes suspended from March 18 until August 22, 2020. Routes 54, 70, 90, A6, A8, B2, H4, S4, V4, W4, and X2 were the only routes that ran during the weekends with the rest of the routes suspended.^[5] On August 23, 2020, more routes came back during the weekdays and weekends returning Metrobus service to 75%.^[6] Most service and routes resumed on September 5, 2021.

In 2023, WMATA approved 24-hour service on 14 routes serving DC: A6, A8, B2, H4, S2, V2, W4, X2, 32, 33, 52, 70, 80, and 92.^[7]

On November 21, 2024, WMATA approved its Better Bus Network Redesign plan, which began development in 2022. Under the plan, all routes would be renamed with easier-to-understand route designations and would modify most of its existing routes to make the bus system easier to use, faster, and more reliable. The Better Bus Network went into effect on June 29, 2025.^[8][9]

Routes

Most DC Metrobus routes operate inside the Washington DC borders. However, some routes would venture into small parts of Montgomery County and Prince George's County to connect to various stations in the Hub-and-spoke system via the old Streetcar routing.

Early morning and late night service was extended to George Washington University Hospital on June 25, 2023.[29] 24-hour service for the X2 was introduced on December 17, 2023.[14]
X8	Originally Operated between Carver Terrace & Lafayette Square, but was later truncated around February, 1978 to only operate between Carver Terrace and Union Station
X9	Formerly known as the, "East Capitol Street Express" Line, which Routes X2 & X4 used to operate as part of. This route was discontinued in the late 1980s and then "reincarnated" in December 2010. As of the late 1980s, X2 has only terminated at the Minnesota Avenue Metro Station, while the X4 was discontinued. Midday service was added on June 24, 2018, which is shortened to operate between Gallery Place and Minnesota Avenue station only.

Routes eliminated before 2025 Bus Redesign

These routes were served by Metrobus at one point but have since been discontinued due to either low ridership, duplication of another route, simplification to other routes, combined into another route, low funding, or transferred to another bus company as it would be cheaper to maintain cost and for another carrier to operate the line. However some routes would be reincarnated into new routes for Metrobus. Examples of reincarnations were the 34, V7, and V8.
