A floating food bridge along the Duwamish River. What better way to reuse the old 520 Bridge pontoons once the replacement span opens in 2014? This was the winning proposal selected by a jury of experts in the Transforming Seattle’s 520 Floating Bridge design competition. And why not? The idea can’t be any more far-fetched than driving a car across Lake Washington on top of floating concrete…
The winning project, South Park Food Bridge by Nicole Lew and David Dahl, proposes towing the pontoons to the banks of the Duwamish River and putting them to dual use, as a floating wetland and community farm. From the project description:
Garden plots are excavated from the pontoon’s upper layer. Operable and removeable greenhouses enhance growing capabilities in Seattle’s climate as well as providing protection from nearby wildlife.
The boardwalk creates a buffer between the agricultural plots and the wetland ecosystem, and creates a public promenade along the river.
