Floating bridges are structures designed to rest on the surface of water rather than being anchored to the ground. They are typically made of buoyant materials, allowing them to float while providing a stable surface for vehicles and pedestrians. These bridges can be used in various settings, including lakes, rivers, and coastal areas. One notable example of a floating bridge is the Evergreen Point Floating Bridge in Washington, which is the longest floating bridge in the world. Floating bridges are advantageous in areas with deep water or unstable soil, as they can be constructed without extensive underwater foundations.
