Once on Mythbusters there was something about the stress on
steel and how, if you got a vibration going at just the perfect
rate, you could bring down a building. I know they were
resurfacing, I wonder about those machines that chew up the
asphalt for replacement. They usually don't just repave over
bridges, they grind some of the asphalt load off. Of course we
will find out eventually, seems like maybe it was a combination of the
heat and the construction activity along with some weakness that
did this bridge in. Those poor people.
