Longest Floating Bridge:
Evergreen Point Bridge, Seattle
Length: 7,580 ft.
Officially known as Governor Albert D. Rosellini Bridge (the Washington statesman who oversaw its creation in the early 1960), this section of State Route 520 connects Seattle to its eastern suburbs via a roadway that floats atop Lake Washington on 33 football field–size pontoons. The design was chosen due to the lake’s unstable bed and the curved nature of the roadway (a common problem for the area, which would explain why the state is home to four of the five largest floating bridges in the world). The aging structure is currently being replaced by a larger, even longer, more modern floating bridge that can even accommodate a light-rail system. wsdot.wa.gov
