M Street Road Closure to Begin October 1

September 13, 2013

(Washington, DC) – DC Water is performing construction activities on M Street, SE as part of the Clean Rivers Project to improve the health of local waterways.

Beginning about Tuesday, October 1, 2013 through December 2014, crews will construct the upper section of an approach channel that will be used to convey storm water to the new Anacostia River Tunnel. Crews will also begin excavation of CSO outfall #017 on M Street, west of Water Street. M Street, east of the traffic circle at Maritime Plaza to Water Street, will be closed during the work. Water Street, which had previously been closed for work on the lower section of the approach channel, will be reopened during this time.

This work will be performed in support of the M Street Diversion Sewer of the Clean Rivers Project (Division E).

Important Information
* Access to the boathouses will be maintained via Water
Street.
* 24-hour parking restrictions will remain in effect on M
Street, between 7th and 14th Streets, until late 2014.
* Some traffic delays within the vicinity of the work zone
are anticipated.
* Traffic signs have been set up throughout the area to
alert motorists to the upcoming traffic changes.
