Looks like the poor old bridge went through the mill.
NOT MoDOT owned
The bulldozer wasn't by chance MoDOT owned, was it?
It was not a drunk driver. A guy was hauling a dozer westbound. Blade caught the end of the pony truss, the impact jerked the dozer off of the trailer and caused the dozer to slide across the deck and cause the damage to the south side of the pony truss. There are gouges in the pavement from the impact. Dozer landed at the west end of the bridge. I was at the site today. The direction that the driver came at the bridge from was a hill and a blind corner. Deck is spongy on the north side by the major damage. The pictures you see there do not tell the full extent of the damage.
May have been a drunk driver?
This bridge is on a straight section of two lane road. I cannot imagine how poor one's driving skills would have to be to do this.
Here is a press release from MODOT Central District on 8 August 2012:
