Answer:
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. ... In the case of suspension bridges, towers are built atop the caissons. The first suspension-bridge towers were stone, but now they are either steel or concrete.
