Decompression chamber
Also nestled atop the inspection barge are two "decompression chambers." This photo shows one of these chambers. The chambers are used by divers after very deep dives. For this project these are typically used after divers conduct inspections of fluke anchors in water nearly 200 feet deep.
As the new SR 520 floating bridge takes shape, crews continue thorough inspections of the concrete pontoons that will serve as the floating foundation. On Nov. 30, 2012, a photographer snapped these shots of an underwater inspection in progress on Lake Washington. The diver scanned the underside of Pontoon W, the eastern cross pontoon, and kept in constant communication with an inspector who maps out the condition of the pontoons. WSDOT will continue to inspect the new pontoons as part of its commitment to delivering a safe, durable bridge that will last 75 years or more.
