Design firms OMA and OLIN have won a competition to design Washington's first elevated park over the Anacostia River.
11th Street Bridge Park will be built on the pillars of a decommissioned road bridge, spanning the Anacostia River and connecting the existing Anacostia Park with the Washington Navy Yard.
The plan also includes providing amenities such as open plaza for markets, festivals and theatrical performances, to attract visitors and neighbouring communities to the bridge.
OMA partner-in-charge Jason Long said: "Our design creates a literal intersection and a dynamic, multi-layered amenity for both sides of the river.
"It simultaneously functions as a gateway, a lookout point with expansive views, a canopy that can shelter programmes and a public plaza where the two paths meet.
"The resulting form of the bridge creates an iconic encounter, an 'X' instantly recognisable within the capital's tradition of civic spaces."
The design of the bridge includes two sloped ramps, where each ramp ends in a waterfall linked to an active filtration system to clear the river.
OLIN partner Hallie Boyce said: "The 11th Street Bridge Park project is an incredible opportunity to contribute to the civic fabric of Washington, DC through the design of an iconic, multi-functional landscape which promotes the health of the river and its adjacent communities acting as a model both nationally and globally."
11th Street Bridge Park is a collaborative work between the DC City Government and the Ward 8-based, non-profit organisation, Building Bridges Across the River at THEARC.
11th Street Bridge Park Director Scott Kratz said: "The OMA + OLIN concept is simply brilliant in the way they captured ideas we heard from residents on both sides of the river and from across the city.
