ASCE Seattle Section Ports and Harbors Committee Monthly Dinner
After half a century of service, the world's longest floating bridge is now clogged by traffic, showing its age, and in need of replacement. The Washington State Department of Transportation (WSDOT) is building a new State Route (SR) 520 floating bridge capable of withstanding heavier windstorms, and moving significantly more people and goods.
Much like a large floating marine dock, the new bridge will consist of concrete pontoons moored to 58 deep water anchors by over 8 miles of steel cables. Varying water depths, soil types, uses, and environmental loads make anchoring this floating structure challenging. The water depths at the anchor locations vary from 30 feet to 210 feet, and subsurface conditions range from very dense to very soft and include soils with unique engineering properties. Ultimately three different types of anchors were used to meet these challenges: drilled shafts, gravity anchors, and fluke anchors.
This presentation will discuss some of the challenging aspects of the design and construction of the mooring anchors for this complex project.
