- M Street (Washington, D.C.)
The name "M Street" refers to two major thoroughfares in the United States capital of
Washington, D.C. Because of the Cartesian-coordinate-based street-naming system in Washington, the name "M Street" can be used to refer to any east-west street located twelve blocks north or south of the dome of the
United States Capitol (not thirteen blocks, as there is no J Street). Thus, in all four quadrants of the city there are streets called "M Street", which are disambiguated by quadrant designations, namely, M Street, N.W., N.E., S.W., and S.E.M Street, N.W.
In Northwest Washington, M Street is a major street downtown and the main east-west street in the Georgetown neighborhood.
M Street N.W. begins at the Key Bridge, which crosses the
Potomac River at the 3500 block. To the west of 36th Street, M Street turns into Canal Road. Georgetown was called Bridge Street until the streets in Georgetown were renamed in 1895 to conform to thestreet name s used in the original federal city. Where 32nd Street would otherwise be, M Street intersects with Wisconsin Avenue. At 29th Street, it meets the western terminus ofPennsylvania Avenue . This is the last major intersection before Rock Creek, which forms the eastern border of Georgetown. The section in Georgetown carries heavy commuter traffic because it connects Pennsylvania Avenue with the Key Bridge and Canal Road.From
Pennsylvania Avenue to Thomas Circle at 14th Street, M is aone-way street with traffic flowing westbound-only, and becomes two-way in Georgetown. This stretch is highly developed, consisting mainly of apartments from 26th to 21st and businesses from 21st to Thomas Circle.From 14th Street to 5th Street N.W., M Street is again two-way. Between 9th and 7th Streets N.W., it passes underneath the
Washington Convention Center . From 5th Street toNorth Capitol Street , it assumes a complex traffic pattern because of the intersections and near-intersections of several high-traffic streets: M, New York Ave/U.S. Route 50 , the northern terminus of I-395, New Jersey Avenue, and North Capitol Street. Traffic is west-to-east from 5th to 4th, east-to-west from New York to 4th, and west-to-east from New York through North Capitol and onto M Street N.E.M Street, N.E.
M Street N.E. runs west-to-east from
North Capitol Street to Florida Avenue between 6th and 7th, where it terminates at the gates ofGallaudet University . Along the way, it uses an overpass to avoid the Union Stationrail yard .Because the intervening Trinidad neighborhood does not follow the grid pattern, M Street does not emerge again until
Bladensburg Road (between 16th and 17th). This two-way stretch dead-ends after intersecting with Maryland Avenue (where 26th Street would be), because the remaining land between that intersection and theAnacostia River is occupied by the National Arboretum andLangston Golf Course . The portion of Washington across the Anacostia follows its own variant of the grid pattern, so while there is no M Street N.E., theDeanwood neighborhood ofAnacostia does have a Meade Street N.E. in the location where M Street would have re-emerged.M Street S.W./S.E.
About a mile south of the Capitol, M Street is a major east-west traffic thoroughfare connecting
Maine Avenue with Interstate 295. ThePotomac River prevents M Street from extending farther west than 6th Street/Maine Avenue. Likewise, theAnacostia River limits M Street S.E. east of 11th to being a named on-ramp for I-295 (the11th Street Bridges to the immediate south and the Southeast Freeway to the immediate north), Water Street S.E. (home of several boating clubs), and Pennsylvania Ave S.E. at the Sousa Bridge before terminating.The most prominent intersection on M Street between those points is with
South Capitol Street . M Street runs along the northern edge of theWashington Navy Yard (between 1st and 11th S.E.) and nearNationals Park , between 1st and South Capitol.The
Anacostia neighborhood, across the river, has its own M Street S.E. Beginning at theAnacostia Freeway (DC-295, roughly where 29th Street would be), it runs diagonally two blocks, merges with Anacostia Road for one block, then straightens out for two blocks before terminating at 34th Street S.E. Its route is blocked by Massachusetts Ave S.E. andFort Dupont Park .
