There is not much new in this presentation to ANC6D about the 11th Street Bridge. It will still include a wider Active Transportation Lane on the downstream side and still feature bike lanes on the approaches.
On this image, you can see the Riverwalk Trail (under the bridge and through the trees in the foreground), the ATL and a small plaza that sticks out into the water between the bridge and the Navy Yard.
And in this you get a view of the ATL which will include two overlooks using the old bridge's piers.
It won't be separated from traffic like on the 14th Street or Wilson Bridge. This is because it's designed to be a neighborhood street, not a highway. The post are the catenary for the streetcar (you can see the tracks on the rigth of the lower rendering).
Though the freeway bridge will open in about a year, the bridge with the ATL won't open until 2013.
Still no word on what will happend to the existing upstream bridge. I say keep it open as a park (add some hoops and a street hockey rink, very nice).
