clifp, there is an old adage that goes something like:
Anyone can build a bridge that won't fall down. It takes some exceptional engineering to build a bridge with just enough material so that is barely stands, but does stand.
And you are 100% right. The extra effort expended making the bridge stronger than required could have been utilized for something worth while. Opportunity cost.

Haha I used to win these bridge building competitions against a bunch of civil engineers. We had a program that would simulate the stresses and whatnot as a train drove across it. The goal was to use as little material as possible. I always ended up with a cheap barely stuck together bridge that would collapse as the train crossed and in some cases and up swinging the train to the other side before destroying it's self.
I viewed a standing bridge as an engineering failure.
