A Washington, D.C., nonprofit will launch a national design competition tomorrow to turn the remains of a highway bridge that spans the Anacostia River into a public park. The proposed 11th Street Bridge Park would connect the Washington Navy Yard, where there has been a recent explosion of growth and development, and the Anacostia neighborhood to the east. Built on top of piers left over from the bridge, it will cost about $25 million.

The competition is being organized by the group Building Bridges Across the River at THEARC, in collaboration with D.C.’s Office of Planning and Department of Transportation. Organizers expect interest to run high. The chance to build “D.C.’s High Line” over the water is hard to resist, and the project tackles the big issues that preoccupy designers right now: social equity, public health, and ecology. Scott Kratz, who is directing the plan, says that by early March he had already fielded inquiries from the Bjarke Ingels Group and James Corner Field Operations, among other leading firms.
