Caisson engineering dates back to at least the 19th century, when it was used to anchor such famous innovation. Because the construction of this bridge was so well-documented, much is known about how the early caisson process ed, pinned to the bottom of the river with granite blocks, go in and excavate the river bottom down to bedrock. ckness (the bends), which was referred to as caisson dismented as suffering from it.
