A bridge has three things to complete the foundation to keep it from collapsing. They are called spread footings, caissons and piles. It also has the deck itself.

ANSWER: Bridges collapse if the math was wrong, if the math was right it may have been built incorrectly and they collapse because the structure has been compromised. Some day Congress will pass an Constitutional Amendment declaring pi to be an even 3.0 to make it easier on public school teachers and civil servants. Then bridges will collapse all the time, except for the outlaw bridges built using the correct math.
