Upper left is an isometric sketch showing one type of RCMPC pier with a strip footing, a column under each girder, a crosshead, and a thin infill wall to prevent floating debris from becoming caught in the columns. Upper right. Cross-section through a later RCMPC type in which a crossbeam carried the load from 4 girders to only two columns, each of which had an individual 'spread' footing. Below is an isometric of a typical spread footing. The slab normally had sloping upper surfaces, giving it the form of a truncated pyramid.
