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.

Numbering

Bus routes operating in or through Virginia are noted with a letter and a number. Bus routes operating in DC or Maryland use only a number, or a letter and a number, as noted below.

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 D.C. and Maryland routes are grouped by their first digit. When this system was laid out in 1936, the following clustering was used:

Missouri supplemental route

A supplemental route is a state secondary road in the U.S. state of Missouri, designated with letters. Supplemental routes were various roads within the state which the Missouri Department of Transportation was given in 1952 to maintain in addition to the regular routes, though lettered routes had been in use from at least 1932. The goal of the secondary highway system was to place state-maintained roads within 2 miles (3 km) of more than 95% of all farm houses, schools, churches, cemeteries and stores. The four types of roads designated as Routes are:

Supplemental routes make up 19,064 miles (30,681 km) (59%) of the state highway system.

Highway designations

The more major supplemental routes of the system are ones assigned with single-letter designations (such as "K"). Minor branch routes and farm-to-market roads, which often end at county roads or are former alignments of the other highways, are typically assigned with two-letter designations consisting of two of the same letter (e.g. "KK"). Additionally, combinations of letters may be used, but always with A as the first letter (such as "AD"); the only exception of this is on Route BA in western St. Louis County. Combinations beginning with the letter R are also used for routes that connect with state parks or other recreational facilities, which is the only use of R on the system; Route AR, a non-recreational route south of Bakersfield, is the only exception to this.
