Usually concrete supports are built IN the water, either resting on the sea floor or actually dug down into it. Then there are a lot of different methods for connecting the land on Side A with the first in-water support, then the second in-water support, then finally to the land on Side B. The part of the bridge that has air underneath it and no support directly underneath is called the "span".
