An overview of the plans for the new 11th Street Bridges, showing three new spans to be built, inside the footprint of the two existing spans. The southern/down-river span will be a "local street that happens to cross a river," connecting Near Southeast directly with Anacostia. It will have wide pedestrian/bicycling paths on both edges, rails for the new city streetcars, and will allow local traffic to cross the river without needing to mix with freeway traffic. The two northern spans will be all freeway traffic, and will include new ramps to and from I-295 to allow for access to northbound 295 and from southbound 295 that hasn't existed before. The $300 million project is expected to be completed by fall 2013. See also this Jan. 2012 YouTube Video explaining the phases of construction. (12/09)
( click for complete project views) Two closer views of the changes to the west side of the bridges configuration. At left, you see the current approach, showing the various ramps and flyovers at 11th Street, some of which lead in small flyovers to and from the two 11th Street Bridges spans, while the bulk of the travel lanes continue east in a sunken path toward Barney Circle at Pennsylvania Avenue.
In the new design (right), the main lanes of the freeway curve at 11th Street to carry the freeway traffic to and from the upstream bridge span, with new single-lane ramps to and from 11th Street. The sunken freeway to Barney Circle is to eventually be replaced with a "Southeast Freeway Boulevard," with access to and from 11th Street. The freeway ramps currently on N Street would be moved to M Street, while the local bridge would return to street/grade level at O Street. The ramps to and from RFK are gone from the new design (and are currently being demolished). (12/09)
The lane configuration of the reconstructed bridges, looking from Anacostia toward Near Southeast. Four lanes each of in-bound and out-bound freeway traffic would use the upstream/northern spans, while local traffic, pedestrians, cyclists, and eventually streetcars would use the downstream southern span.
