Looking at the damage I keep thinking that there is going to have to be some sort of investigation into lack of maintenance/preparedness at those bridge crossing. Things like insufficient rip-rap at bridge piers and abutments, lack of channel clearing, etc. From a number of the pics/vids it seems that these measures would probably have prevented some of the destruction.
I don't want to start a panic, but now may be a good time to stock up on essentials as Metro Van's capacity to produce those goods is limited. With road rail access to anything east of us is essentially cut off, we'll have to look south for a lot of our daily goods. Things are going to get expensive in a hurry.
