11th St. Bridge work to disrupt traffic

The reconstruction of the 11th Street Bridge over the Anacostia River is the District's biggest transportation project, but so far, much of the work has been in the middle of the river or on the shoreline, usually away from traffic.

Project managers said that as the construction advances this year, drivers will see more of an impact on traffic, though mostly at off hours. Here's a schedule for such work from the District Department of Transportation.

Starting tonight and continuing through Nov. 23, the number of lanes on the bridge will be reduced between 8 p.m. and 5 a.m., but two inbound and outbound travel lanes will remain open at all times.

Lane restrictions on the inbound bridge will reduce the ramp from northbound Interstate 295 and from 13th Street SE to one lane. Lane restrictions on the outbound bridge will reduce the ramp from the Southeast-Southwest Freeway to one lane.

11th Street SE: Starting today, the left lane of 11th Street SE, from M to N Street SE, will be closed. Two lanes will remain open for traffic.

N Street SE: From 9:30 a.m. to 5 a.m. Tuesday through Friday nights, both lanes of N Street SE will be closed between 12th and 11th Street SE. Follow detour signs.

Other lane restrictions
Drivers may encounter other lane restrictions on the bridge, local streets or the freeways approaching the bridge through Nov. 23. These are the potential blockages.

* One lane in each direction of I-295/DC295 between Pennsylvania Avenue and Howard Road.
