They news here was making mention about the I-40 bridge collapse 5 years ago here in OK when a drunk barge driver hit a pylon that brought it down. Rebuilt it in record time. Just from looking at the pics, it looks like the pylons on the near side of that pic gave way. What happens is the water permeates the concrete pylons and rusts the rebar inside. That causes the rebar to expand up to several times its normal size until the concrete can't hold the pressure anymore and explodes. Sad day for all, and a few more families will be a few million dollars richer due to this unfortunate accident.

Even though a bridge normally is constructed with a safefactor of 10 it only require failure in one critical spot for it to collapse. It's not the first bridge to give in. Probably a construction error in the way that they didn't think of some factor. Vibrations will eventually cause fatigue. Have you been standing on a bridge when a truck passes and felt how much the bridge moves? It's amazing.

Roadsalt can really be effective in corrosion on steelbridges.
