List of Metrobus routes (Washington, D.C.)

This is a list of bus routes operated by the Washington Metropolitan Area Transit Authority (WMATA), branded as Metrobus.

Many are the descendants of streetcar lines operated by the Capital Transit Company or its predecessors.

At one time, odd numbered routes were express routes, but that distinction has been abandoned.

Most Maryland and Washington, D.C., routes are grouped by their first digit.

When this system was laid out in 1936, the following clustering was used:[citation needed]

WMATA New Flyer XN40 running on the 32 route in the "Local" scheme.
A New Flyer DE40LFA running on the 37 in the "MetroExtra" scheme.
Passengers board an Orion VII on the 5A "Express" bus at Rosslyn , headed for Dulles International Airport . Pictured here is 2704 (now retired), which was taken before its rehabilitation in 2012.
WMATA Orion V 9652 (now retired) at Greenbelt station in Prince George's County, Maryland , headed for New Carrollton . Route T17 was replaced by routes G12 & G14 on December 17, 2010.
