Employees and visitors of the Washington Navy Yard (WNY) accessing the base may experience increased traffic and delays to several WNY gates and along M Street due to the ongoing 11th Street Bridge reconstruction and the DC Sewer Overflow project slated to start in the next few weeks. Employees and visitors are urged to watch for gate closure announcements and changing traffic patterns during the construction period.
The 11th Street Bridge reconstruction project, which began in December 2009, will be replacing the two existing bridges with three new bridges and improve the related interchanges. Expected to be completed by Fall 2013, the project will improve mobility by providing separate freeway and local traffic connections to both directions of DC 295, the Southeast-Southwest Freeway and local streets on both sides of the Anacostia River. The new local bridge will be at grade and will allow increased access to and from the WNY N Street and O Street gates when the local 11th Street bridge opens at the end of 2012.
Later this month, construction at the O Street & 11th Street intersection will close the O Street gate to outgoing traffic for approximately three weeks. This is in support of the relocation of the 295 ramp on 11th Street from N Street to M Street, which is scheduled to occur during Memorial Day weekend. After the relocation, traffic headed south on DC 295 will need to access the freeway from the new ramp entrance located at M Street & 11th Street.
The DC Water Clean Rivers Project Combined Sewer Overflow Control Program is a federally mandated project that will bring the district into compliance with clean water regulations.
The DC Water project duration along M Street is approximately 15 months, starting June 2012 through August 2013. Four utility companies will conduct relocations of lines at the 9th Street & M Street intersection prior to DC Water work. This work is scheduled for April-May, 2012. Naval Support Activity Washington (NSA Washington) will likely close the 9th Street gate to vehicular traffic for approximately two weeks in late April or early May to expedite the construction schedule.
NSA Washington is working to coordinate the utility construction, as well as turnstile maintenance, to minimize duration of traffic impacts. Outside of the two-week gate closure, other construction may require reducing vehicle traffic to inbound or outbound only and limited movements in and out of the 9th Street gate.
WNY employees will be notified of coming events once specific construction dates have been determined. For information about the DC Water construction project, please visit the DC Water web-site at www.dcwater.com/workzones/projects/cleanrivers.cfm
