A pontoon bridge is a temporary structure that is created by forming a bridge over a body of water using a series of interconnected floating platforms or pontoons. This type of bridge is employed when a quick and efficient means of crossing a river, lake, or other waterway is required, and traditional bridge construction is not feasible or cost-effective.
The pontoons of a pontoon bridge are typically made of metal or buoyant materials such as wood or rubber, and they are assembled side by side to form a pathway across the water. The pontoons are connected by beams or other rigid components, which ensure the stability of the bridge and prevent the pontoons from drifting apart. Additional support may be provided by anchoring the bridge to the banks of the waterway or by securing it with cables or ropes.
Pontoon bridges are often used in military operations for swiftly crossing water obstacles, allowing troops, vehicles, or equipment to move easily from one side of the water to the other. They can also be utilized in disaster relief efforts or construction projects, providing a temporary means of transportation until a more permanent solution is implemented.
Due to their temporary nature, pontoon bridges are easily assembled and disassembled, and they can be transported to different locations as needed. Their versatility, cost-effectiveness, and quick deployability make them a valuable asset in situations requiring rapid mobilization and efficient bridge construction.

The word "pontoon" originated from the French word "ponton", which was derived from the Latin word "pontonem", meaning "floating bridge". In the early 17th century, the term was introduced into English, referring to a flat-bottomed boat or float used for supporting a bridge. The word "bridge" traces back to the Old English word "brycg", which came from the Proto-Germanic word "*brugjo", meaning "way over". Over time, the two terms were combined to form "pontoon bridge", denoting a floating structure that allows passage over water.
