Piers are the vertical structure that supports a bridge. They are not often taken in account as a beautiful an important part of a bridge; they are usually the ones that remain after a disaster, mainly because they must be located over solid rock to be stable.



To build a pier or a group of them represents a technical problem: in many parts of the history of bridges and construction the process that took the longer time was the piers. This is a direct consequence of the location of piers: in order to support a bridge, piers must be in most of the cases, underwater; rising the pressure that they need to support producing technical problems.



Piers therefore, must be taken in account when the bridge is built and designed as a main element that provides support and stability to the bridge.
