Pontoon bridge the pontoons, increasing the drag from river current and potentially damaging the bridge. See below for floating pontoon failures and disasters. In ancient China, the Zhou Dynasty Chinese text of the "Shi Jing" ("Book of Odes") records that King Wen of Zhou was the first to create a pontoon bridge in the 11th century BC. However, the historian Joseph Needham has pointed out that in all likely scenarios, the temporary pontoon bridge was invented during the 9th or 8th century BC in China, as this part was perhaps a later addition to the book (considering how the book had been
Pontoon (boat) Pontoon (boat) A pontoon boat is a flattish boat that relies on pontoons to float. These pontoons (also called "tubes") contain a lot of reserve buoyancy and allow designers to create massive deck plans fitted with all sorts of accommodations, such as expansive lounge areas, stand-up bars, and sun pads. Better tube design has also allowed builders to put ever-increasing amounts of horsepower on the stern. Pontoon boat drafts may be as shallow as eight inches, which reduces risk of running aground and underwater damage. The pontoon effect is when a large force applied to the side capsizes a pontoon
