EXCELLENT video and analysis.
Looking at all that, one has to wonder why a bridge was constructed so the pilings were so close to the channel the ships went up.
It seems like any one could figure out this was a recipe for disaster.
This collision and collapse of the bridge was a metaphysical certitude, given the traffic volume and incredible size of modern cargo ships. Hundreds or thousands of these ships passing under the bridge per year...the odds eventually will win out.
One wonders why no one ever thought of that, given the half century+ age of the bridge. Those supports should have been previously retrofitted with this eventuality in mind. But now we are talking about government....where ineptitude is the rule of the day.
