It’s not one bridge it’s thousands of bridges, it’s just not know how critical each bridge is. Or how critical it becomes when another one is down.

Look at all the other major engineering failures in history, it’s always small things (a gasket) on a bad day (too cold?) that somehow works day after day until one day it magically doesn’t and you get the Apollo incident. Everything goes catastrophic over tiny things. Imagine if NASA fired half their team before that incident. The only guy who knew the gasket can’t get cold might not still be there because Ned got laid off.
