| Seattle's 520 Floating Bridge | 
The 
Washington State DOT has required that the design-build team for a new bridge must reuse or recycle the existing bridge in a sustainable way. An 
international design ideas competition has been born of this challenge. Favorite options for reusing the existing pontoons have included 
floating docks, 
breakwaters, and piers. It's likely that the winner of the ideas competition will be more creative.
Results of the competition are to be announced live at the 
2012 Seattle Design Festival and subsequently posted 
online. Log on to view the winning design. Did you have a better idea? What other design options come to mind? Please share your comments here.
