Top best answers to the question «How are bridges built underwater»

  • Underwater bridges, typically constructed of logs, sand and dirt just beneath the surface of the water in a river or similar narrow body of water, allow heavier vehicles to cross the river driving through only shallow water.

When bridges requiring piers are built over a body of water, foundations are made by sinking caissons into the riverbed and filling them with concrete… Next, the anchorages are built on both ends, usually of reinforced concrete with embedded steel eyebars to which the cables will be fastened.

How do they build a bridge over deep water?

  • Next method is for the bridge build over deep water body (river or sea). Cofferdam technique is used in this case. In this method, a wall enclosing an area is build inside the water and water is continuously pumped out from the area. After that, foundation of the bridge(the pillars) is constructed inside the cofferdam.
  • While every condition is different, depending on the type of bridge, the body of water over which it is being built, and the soil conditions on which the bridge piers rest, here is the general approach to building bridges underwater: A foundation is drilled. The surrounding water is removed. Water is removed with a pre-fabricated frame.
