Very sad for the apparent loss of life, for the impacts to shipping, and for all the extra traffic that will dumped into the tunnels until a new bridge can be constructed. (it will take years) In the collapse video there are clearly at least four work vehicles with yellow flashing lights on the span.
But I also can't help but feel a little sad for the loss of a beautiful structure. I only maybe ever drove over it twice, but it was clearly visible from some of the tunnel approaches.
One of those times I drove it was really late, after a wedding, and the road was deserted. Surely, therefore, the timing of this incident could have been a lot worse.
and the engineer in me can't help but be fascinated by watching how the bridge reacts to the strike. I keep scrolling that video back and forth. The far end actually lifts up a little before the truss tears apart, and when it comes back down it has enough momentum to destroy the footing it had been resting on.
