A pontoon bridge (or ponton bridge), also known as a floating bridge, 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. Most pontoon bridges are temporary and used in wartime and civil emergencies.
Of the pontoons, 21 are longitudinal pontoons that support the deck and structure and are 360 by 75 by 28 feet (109.7 m × 22.9 m × 8.5 m) and weigh 11,000 short tons (10,000 t); [4] 54 smaller supplemental pontoons, weighing 2,500 short tons (2,300 t), are used to stabilize the weight of the bridge; and two "cross" pontoons, weighing 10,100 ...
167 m (548 feet) Width. 9.80 m (32 feet) History. Opened. 1888, restored 1939 and 2006. Location. The Queen Emma Bridge (Dutch: Koningin Emmabrug; Papiamento: Brùg di Ponton, Brùg di Punda) is a pontoon bridge across St. Anna Bay on Curaçao island in the Dutch Caribbean. It connects the Punda and Otrobanda quarters of the capital city ...
The water depth below the pontoons ranges from 80 to 340 feet (25 to 105 m). [4] In its marine environment, the bridge is exposed to tidal swings of 16.5 feet (5 m). [6] The pontoons for the bridge were fabricated in the Duwamish Waterway in Seattle; during fabrication, two of the pontoons sank. When they were attached for the first time, and ...
Completed 2008. Spans 5,153.277 feet (1,571 m). Located near New Amsterdam in Guyana. Demerara Harbour Bridge. Completed 1978. Spans 6,074 feet (1,851 m). Located immediately south of Georgetown, Guyana, it is constructed with steel pontoon units and is the fourth longest floating bridge in the world.
A pontoon boat is a flattish boat that relies on floats to remain buoyant. These pontoons (also called tubes) contain much reserve buoyancy and allow designers to create large deck plans fitted with a variety of accommodations including expansive lounge areas, stand-up bars, and sun pads. More horsepower is now able to be applied to the stern ...
