By far the largest District Department of Transportation (DDOT) project underway, the 11th Street Bridge Project is critical to improving travel and achieving the larger vision of the Anacostia Waterfront Initiative.
The project is replacing two bridges built in the 1960s with three new bridges that separate local and freeway traffic.
The new freeway bridges also provide the missing interstate connections between 1-695 (also known as the Southeast-Southwest Freeway) and DC-295, fixing a long-standing deficiency that forced motorists to use local streets to connect to and from both freeways.
The new 11th Street Bridges will provide critically needed infrastructure, relieve local streets of interstate traffic and connect pedestrian and multi-modal traffic on both sides of the Anacostia River.
The first phase provides three new bridges; a new 14-foot-wide pedestrian and bicycle sidewalk on the local bridge that connects to the Anacostia Riverwalk Trail; drainage and other environmental investments to treat all storm water within the project area; an additional evacuation route; and design accommodations for the future streetcar system.
In order to encourage contractors to develop innovative ways to deliver the project efficiently under financial constraints, DDOT used a design-build-to-budget procurement method that not only significantly reduced the cost by approximately $100 million, but also allowed DDOT to accelerate the construction schedule by five months. Phase I was completed ahead of schedule and within budget in July 2013.
Because of the success of Phase I, FHWA authorized DDOT to proceed with the remaining 20 percent (Phase II) of the project at an additional. Phase II of the 11th Street Bridge Project will further improve connections along the I-695 (aka SE/SW Freeway) and lay the groundwork for its reconstruction to a level Boulevard between 8th Street SE and Barney Circle (Pennsylvania Avenue). Phase II construction started in July 2012 and is scheduled to be completed in mid-2015.
When completed in mid-2015, Phase II of the 11th Street Bridge Project will:
