The new 11th Street Bridges are already open and have been for some time. Work continues on Phase II, but for cyclists and pedestrians most of the relevant work is complete. The new local bridge includes a much wider sidewalk with overlooks of the river that jut out over the old bridge's supports (and cyclists may use the roadway if they don't like those). There's also a new parklet on the old bridge's southwest footprint that includes a trail connection between the Navy Yard Promenade and the bridge with a trail spur upriver for the Anacostia Riverwalk Trail.
DDOT will be hosting a celebration of the
Local 11th Street Bridge commemorating the District Department of Transportation’s decade of transportation advancements and the full opening of the local bridge to two-way traffic, bicyclists and pedestrians. This free, family-friendly event will take place on Saturday, September 7, 2013 from 12 p.m. to 3 p.m.
