A pile bridge is a structure that uses foundations consisting of long poles (referred to as piles), and which are hammered into the soft soils beneath the bridge until the end of the pile reaches a hard layer of compacted soil or rock. Pile bridges have been used to cross rivers and other geological chasms since at least the time of the Roman Empire.
