A pontoon bridge is a type of floating bridge that uses pontoons or barges to support the bridge deck. These structures are often used in situations where building a traditional bridge is impractical, such as over rivers or lakes. They can be quickly assembled and disassembled, making them ideal for temporary crossings. Pontoon bridges are commonly used by military forces and for recreational purposes. They can accommodate vehicles and pedestrians, depending on their design. The flexibility and ease of construction make them a valuable option for connecting areas when permanent solutions are not feasible.
