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.

How are suspension bridges built over water?

How do suspension bridges stay up?
Suspension bridges get their name from the fact that the roadway is suspended by cables from two tall towers. Most of the weight is supported by the two towers. They, in turn, pass the compression forces from the cables directly into the ground. Suspension bridges also have smaller cables called suspenders.
How were bridges built underwater?
Large and long piles are drilled into the floor of a water body. A massive drill makes a hole deep enough to form a sturdy base. A foundation needs good bearing soil or a hard solid surface, like the earth’s rocky crust. Hence, a drill is used to excavate underwater until it reaches good-bearing soil or a rocky base.
What makes a bridge so strong?
Trusses help a bridge spread out the weight that it has to carry. But not all bridges are made of trusses. If a bridge has to cross a really wide body of water, it might be too difficult or expensive to build a truss bridge. So engineers designed another kind of bridge called a suspension bridge.
