The new 2.2-mi. (3.5 km) San Francisco-Oakland Bay Bridge East Span, with a revolutionary seismic design has claimed the 2015 Grand Conceptor Award — the engineering industry’s top prize for excellence — at the annual Engineering Excellence Awards, sponsored by the American Council of Engineering Companies (ACEC)
More than 600 attended the black-tie Engineering Excellence Awards Dinner and Gala held recently in Washington, D.C. The Gala was hosted by Comedian Rex Havens and recognized 170 preeminent engineering accomplishments from throughout the world.
Designed by the joint venture of T.Y. Lin International and Moffatt & Nichol, the new bridge is the world’s longest single-tower, self-anchored suspension bridge, the world’s widest bridge, and was devised to withstand the most powerful earthquake that can be predicted in a 1,500-year period.
The superstructure showcases groundbreaking bridge design such as a 525-ft. (160 m) tall tower with separate steel legs which move independently and serve as giant shock absorbers during an earthquake to avoid major damage to the main bridge structure. The project also includes a 1.2-mi. (1.9 km) long, twin-viaduct Skyway consisting of specially designed expansion joints which allow structure segments to move and slide several feet also preventing major damage during a seismic event.
With its visually-striking design, the new East Span is now an iconic and seismically-resilient landmark which ensures the safety of more than 300,000 vehicles each day.
The new San Francisco-Oakland Bay Bridge East Span also joins the 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 Hoover Dam Bypass (2011) as recent Grand Conceptor Award winners.
