List of Metrobus routes in Maryland

Route F4 in Silver Spring

Route P12 at Addison Road station

Route Y7 at Silver Spring Transit Center

This is a list of bus routes operated by the Washington Metropolitan Area Transit Authority (WMATA), branded as Metrobus in Montgomery County and Prince George's County in Maryland. Most of the routes operated under Streetcars in Washington, D.C. and Maryland prior to the 1960s.

Numbering

Most Metrobus routes in MD were formerly designated with a letter followed by a number, but some routes had double-digit numbers. The routes in Prince George's County would typically have a letter followed by two numbers. ^{[1] [2]}

Odd-numbered routes were typically part-time variants of even-numbered routes. At one time, odd-numbered routes were express routes, but that distinction was later abandoned. Most odd-numbered routes operated during rush hours and/or with limited bus stops that had a few of them running into the off-peak hours.

As of WMATA's Better Bus Redesign beginning on June 29, 2025, all the routes entirely within Maryland begin with an "M" and a "P."

History

Many current routes operate under former streetcar routes. The Streetcars provided the main transportation in the Maryland area from the 1800s to the 1960s. ^[3] Two separate companies, the Washington, Virginia, and Maryland Coach Company (WV&M), and the Washington Marlboro and Annapolis Motor Lines (WM&A), would also operate on the former streetcar routes and provide service to parts of MD when the Streetcars ended service. In 1973, WMATA acquired the two bus companies along with other bus companies to form its current Metrobus system. ^[4] At one point, most MD routes would enter into Downtown before Metro was built in which all buses would terminate at stations in various locations. Today, the main MD hub is at Silver Spring Metro station.

When Ride On began service, most Metrobus routes in Montgomery County were slowly transferred into Ride On routes through the years as it would be cheaper to operate under another carrier. The same thing went with TheBus.

Due to the COVID-19 pandemic, the Metrobus service was mostly reduced to Sunday service schedules during the weekdays with selected routes suspended from March 18 to August 22, 2020. Routes 83, A12, C4, D12, F4, J2, K6, P12, T18, Y2, and Z8 were the only routes that ran during the weekends with the rest of the routes suspended. ^[5] Beginning on August 23, 2020, more routes came back during the weekdays and weekends returning the Metrobus service to 75%. ^[6] Most of the Metrobus service and routes resumed on September 5, 2021.

On November 21, 2024, WMATA approved its Better Bus Network Redesign plan, which began development in 2022. Under the plan, all the 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 Redesign was implemented on June 29, 2025, with all the Maryland routes being renamed with an "M" for the Montgomery County routes and a "P" for the Prince George's County routes. The routes that primarily serve Washington, DC have bus stops in Maryland and were renamed with a "C" for crosstown and a "D" for downtown. ^{[7] [8]}

Routes

Most of the Maryland buses remain inside of Prince George's County and Montgomery County. However, a few routes enter into Washington DC, which were a part of their former streetcar lines. Only one current route (P90) operates between Maryland and Virginia.

Routes eliminated before the Better Bus Redesign Network

These routes have been served by Metrobus at one point but have since been discontinued due to either low ridership, a duplication of another route, a 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 are routes C8 and Z6.
