I think there were two.
That’s what the local news said yesterday.
This bit cracked me up, too:
“The two critical components on that bridge are the two load-bearing pylons on each end, closest to the shore. They are bigger, thicker and deeper than anything else. These are the anchor points and they knew that hitting either one one of them would be a fatal wound to the integrity of the bridge.”
So the genius plotters deduced that the place to crash a boat to do the max. damage to the bridge was....wait for it...the part *in the water*. As opposed to, what, the span in the air? Mental.
