A pontoon bridge (or ponton bridge), also known as a floating bridge, uses floats or shallow- draft boats to support a continuous deck for pedestrian and vehicle travel. The buoyancy of the supports limits the maximum load that they can carry. Most pontoon bridges are temporary and used in wartime and civil emergencies.
Submerged floating tunnels can be anchored to the seafloor (left) or suspended from a pontoon (right) A submerged floating tunnel (SFT), also known as submerged floating tube bridge (SFTB), suspended tunnel, or Archimedes bridge, is a proposed design for a tunnel that floats in water, supported by its buoyancy (specifically, by employing the hydrostatic thrust, or Archimedes' principle).
A pontoon boat is a flattish boat that relies on nautical floats for buoyancy. Common boat designs are a catamaran with two pontoons, or a trimaran with three. [2] In many parts of the world, pontoon boats are used as small vehicle ferries to cross rivers and lakes. [3] An anchored raft-like platform used for diving, often referred to as a pontoon

Rosellini Bridge, carries Washington State Route 520 across Lake Washington from Seattle to its eastern suburbs. The 7,710-foot-long (2,350 m) floating span is the longest floating bridge in the world, [ 3 ] as well as the world's widest ...
The Dardanelle pontoon bridge over the Arkansas River connecting Pope and Yell counties at Dardanelle, Arkansas. Replacing a private ferry when it opened in 1891, the movable structure operated as a toll bridge.

The PMP Floating Bridge (Russian: Понтонно-мостовой парк, ПМП "pontoon / bridge park") is a type of mobile pontoon bridge designed by the Soviet Union after World War II. The bridge's design enables for a quick assembly of its parts. [1] It has a carrying capacity of 60 tons. [1] The bridge was originally mounted on a ...
