Pontoon Bridge

A pontoon bridge or floating bridge or bridge of boats is a bridge that floats on water and in which barge- or boat-like pontoons support the bridge deck and its dynamic loads. While pontoon bridges are usually temporary structures, some are used for long periods of time. Permanent floating bridges are useful for sheltered water-crossings where it is not considered economically feasible to suspend a bridge from anchored piers. Such bridges can require a section that is elevated, or can be raised or removed, to allow ships to pass.

Pontoon bridges are especially useful in wartime as river crossings. Such bridges are usually temporary, and are sometimes destroyed after crossing (to keep the enemy from using them), or collapsed and carried (if on a long march). They were used to great advantage in many battles throughout time, including the Battle of Garigliano, the Battle of Oudenarde, and many others.

Pontoon bridges have been in use since ancient times.

    Home! Yes! she would see Trafalgar Square, again; and Nelson on his plinth; and Chelsea Bridge as it dissolved into the Thames at twilight ... and St. Paul’s, the single Amazon breast of her beloved native city.
