Seattle's gleaming new 1.5-mi. SR 520 Floating Bridge has won the 2017 “Grand Conceptor” Award signifying the year's most outstanding engineering achievement in the 50th Anniversary Engineering Excellence Awards (EEA) — a national juried competition sponsored by the American Council of Engineering Companies (ACEC).
More than 700 attended the 50th Anniversary black-tie Engineering Excellence Awards Gala on April 25 in Washington, D.C.
Hosted by Actor/Comedian Kevin Nealon, the event recognized 162 preeminent engineering accomplishments throughout the nation and the world.
Designed by engineering firm HDR, the new SR 520 Bridge is the world's longest and largest floating bridge. The superstructure is supported by 21 of the heaviest, widest and deepest longitudinal pontoons ever built, each weighing nearly 11,000 tons. Further stabilized by 54 supplemental pontoons and cables and anchors, the bridge can resist winds of up to 98 mi. per hour and 6.3-ft. wave heights or the equivalent of a 100-year storm.
The new SR 520 Floating Bridge joins the San Francisco Air Traffic Control Tower (2016); the San Francisco-Oakland Bay Bridge East Span (2015); Wacker Drive/Congress Parkway Reconstruction (Chicago, 2014); Kauffman Center for the Performing Arts, (Kansas City, 2013); Lake Borgne Storm Surge Barrier (New Orleans, 2012); and the Hoover Dam Bypass (2011) as recent ACEC Grand Conceptor Award winners.
