With the SR 520 Floating Bridge and Landings Project, the Washington State Department of Transportation replaced the existing floating bridge, also known as the Governor Albert D. Rosellini or Evergreen Point Floating Bridge, over Lake Washington. At more than 7,700 ft long, the new SR 520 Floating Bridge achieved a Guinness World Record for the longest floating bridge. Working with the design-build team, SGH served as the structural and marine engineer, as well as the engineer of record for many critical tasks on this project.
