So what, Hellary has been standing for 60, but she has a thicker buttress.

Yet amazingly, this flawed bridge stood for what? 50yrs? It stood for 40 years. It was designed to last 50 years, but that was with four lanes of traffic. Not the eight lanes that it carried since the four shoulders were converted to traffic lanes in 1988.

The idea is that a structure stands for its rated life, during which time it is periodically imspected and maintained. After its rated life it is reevaluated to see if its life can be extended.
The whole idea is that a properly maintained structure, within its rated life, has a very small probability of catastrophic failure.
That it failed indicates that it either was not maintained properly or it was poorly designed.
