This reminds me of the 2002 Arkanss River bridge collapse on I 40 at Weber's Falls Ok. The pilot of the tug passed out, the barges struck a support pier. 14 people died & 11 were injured. It happened early on a Sunday morning when traffic was light ot inexperiecednherwise the casualities could have been much worse. There was a fishing tournament on the river that weekend. Fishermen pulled several people out. One of the first in was a ABF tractor/pups. The driver barely survived, had the fishermen not been there he said he have died. The tractor was an almost new Mack, one trailer, also new was a UPack load with a family's household goods. I have wondered about how the company explained to the family that their possessions were on the bottom of the Arkansas River.
There is a good article about the tragic accident on Wikipedia.
