(This post is an abbreviated version of the South by West article that will appear in December's
Hill Rag).
Over the past several months,
DDOT has been working on a transportation planning study of
the M Street, SE/SW corridor.
The study
area includes most of ANC 6D, which includes
everything south of the Southeast/Southwest Freeway to the Washington Channel
and Anacostia River. The study began in early
2012 and after three community meetings and months of study by DDOT and their
consultant
CH2MHILL, three alternatives were developed for the corridor and
surrounding streets. Each of the alternatives are distinct, although some
aspects of each alternative are common.
The first alternative would remake M Street as a “Main
Street” which would accommodate more transit service. Under this alternative,
there would be a median of variable width, including a center turn lane on the
Southwest portion of M Street, two travel lanes on each side of the street, and
the outer lanes would be an exclusive transit lane for streetcars, Metrobus,
and commuter buses. Street parking that currently exists on M Street would be removed under this scenario since the parking lane would be taken up
by the transit lane. Right turns would be restricted to certain intersections
throughout the corridor so the transit vehicles are able to travel more quickly
on the street. In order to compensate for the removal of a traffic lane on M
Street, a second travel lane would be added to each side of I Street
by removing on-street parking. The bike lane configuration currently on I
Street would change to include a mixed travel and bike lane in each
direction. In addition, P Street would be widened from one travel lane to
two travel lanes between 4th Street and South Capitol Street during
peak hours. One-way traffic on some streets would be converted to two-way
streets.
Under the second alternative, or the “Balanced Linkages”
scenario, M Street would accommodate cars, transit, and bike lanes. The
typical cross-section of M Street west of South Capitol Street would have an
eight-foot cycle track, an eight-foot parking lane, a 12-foot shared travel
lane for general purpose and transit vehicles, and an 11-foot travel/turn lane
in each direction. This scenario reduces
the number of travel lanes from three currently to two lanes in each direction
on M Street. Streetcar service would be placed along I Street, where the
parking lane would be removed and replaced with a shared vehicle/transit lane. The
streetcar line would connect to 7th Street on the western side. On-street
parking on P Street would be removed as well, replaced with a shared
travel/transit lane that would serve the DC Circulator (assuming service is
restored to Southwest). No Southwest streets would be converted to two-way
streets under the second alternative.
Alternative number three, or the “Mobility Arterial”
scenario would make M Street three travel lanes in each direction with
the outer lane serving as a shared travel/transit lane. Streetcars would run on
this shared lane. No parking would be
provided on M Street under this scenario. However, the middle travel lane
would be shared with bicycles. The current configuration of I Street would
not change under this scenario. Similar to alternative number two, no Southwest
streets would be converted to two-way streets under the third alternative.
