A pontoon bridge (or ponton bridge), also known as a floating bridge, is a bridge that 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. Floating bridges have been in use since ancient times to establish a crossing over water barriers where construction of a normal bridge was not feasible. Instead of spanning the gap between two fixed supports, it rests on hollow pontoons or barges that displace water and use buoyancy to hold up the road deck. Floating structures are no longer niche solutions limited to marinas or temporary platforms. As someone who has worked closely with waterfront and marine.
