A joint-venture team began reconstruction work this month of the longest floating bridge in the world, while two of its members also near completion on a key related facility to build massive pontoons.
Omaha-based Kiewit Corp., General Construction Co. of Federal Way, Wash., and Manson Construction, Seattle, began work on Sept. 2 on its $586.5-million contract to rebuild Washington's state Route 520 floating bridge over Lake Washington—the longest in the world at 1.44 miles. The bid for a new, six-lane, 115-ft-wide floating bridge came in $163.5 million under WSDOT's anticipated mark this summer, says Mike Cotten, the agency's construction director.
