On a lighter note, all of the children on the school bus that was crossing the bridge when it collapsed are safely evacuated. ---

[QUOTE=Captain Socks] Wait, just in, three. [/QUOTE] CNN reporter on the scene just relayed a report from a police officer on rescue duty that had counted seven bodies so far … Toll may well keep rising, that looks just awful. ---

[QUOTE=FlyingCowOfDoom] ETA: I found the bridge on Google Maps because I was curious as to the size of the bridge. Here’s a [link](http://maps.google.com/maps?f=q&hl=en&geocode=&q=minneapolis,+mn&ie=UTF8&ll=44.978938,-93.24411&spn=0.006436,0.016909&t=h&z=17&om=1). That’s a pretty big bridge. [/QUOTE] From my one visit to the Twin Cities, I think that weir on the left of your picture is the head of navigation of the Mississippi River (i.e., the furthest you can navigate up river from the Gulf of Mexico). So, it’s a big bridge because it’s a big river. ---

I’m keeping my fingers crossed and praying that the toll doesn’t rise any higher. God, the footage on CNN looks awful. ☹ ---

[QUOTE=FlyingCowOfDoom] This is awful. I can’t believe that this sort of thing can happen in 2007. It’s inconceivable. Someone on the news just said, “Certainly there will be tons of engineers coming to figure out what happened.” I guess they have to come to close the stable door. :rolleyes: :mad: [/QUOTE] No, it’s not closing the stable door - investigating this is the only way they’ll be able to prevent similar bridge collapses from happening in the future. It’s tragic but so many safety rules come about because of things learned through failure. For an excellent read on the topic, check out [To Engineer is Human: The Role of Failure in Successful Design, by Henry Petroski](http://www.amazon.com/Engineer-Human-Failure-Successful-Design/dp/0679734163/ref=pd_bbs_sr_1/105-7982423-5202068?ie=UTF8&s=books&qid=1186016346&sr=8-1). The engineers are coming based on the assumption that the road work was being done in accordance with known safety rules. Which means that something that is currently unknown was going on with the bridge. They **have** to find out what happened. Before the next bridge goes down, maybe this time with the schoolbus still on it. I grant that it’s damned cold comfort to anyone wounded in this collapse or who lost a loved one. ---

What freaky shit. I used to take that stretch to work every day. I-35 is THE highway in the state. Traffic is going to be a nightmare for a long time. Someone’s ass is going get sued off. ---

There’s a construction guy (unrelated to the current construction) on the Fox stream I linked, and he’s saying a MODOT investigation in 2006 saw fatigue fractures on some steel beams on the bridge. He also said it was undergoing a deck rehabilitation, but that shouldn’t cause weakness. ---

We’re OK. My husband crossed that bridge at 4:30 this afternoon. Fucking scary. I am trying to get ahold of my friends to make sure they’re all OK. ---

I heard they were pouring concrete. Wet concrete is heavier than dry. They were planning on closing down the road this weekend to do more work. Heads will roll about this. Civil engineers and contractors, probably. ---

My gut reaction was that this was fatigue-related. Certain details can propagate cracks and in a non-redundant load path bridge one crack in the wrong place will do this. I don’t believe the jack hammering or the placement of concrete would have anything to do with it. ---

Texting is working better for me than making cell calls. Hopefully it’s less intensive on the system. I’m about 12 blocks from this bridge, but it’sthe opposite direction from where I make my commute. ---

SIL got a cell signal…she’s in the mother of all traffic jams, but she’s safe, thank God. Glad to hear all the MinneDopers checking in safely. Man, I think back to when I was a kid, and how terrified I was of bridges. When we’d drive over them, I’d be huddled up in a ball on the floor (heh…obviously predating mandatory car seats for kids). Then, one day, I just decided “know what? This is silly. It’s a bridge. It’s not going to fall down or anything”. Since then I’ve been fine on them, but there’s always that little twinge in the back of my mind. That must’ve been one unfathomably terrifying scene for anyone there. ---

**Garfield** , apparently there were two piers on either side, holding a truss which had the road way on top: [pic.](http://wcco.com/slideshows/local_slideshow_213210219/view?slide=3) From the damage photos, it appears that the truss rolled or twisted [off](http://wcco.com/slideshows/local_slideshow_213194533/view?slide=11) of the pier. My preliminary suggestion is that the connection between the pier and the truss failed in some way, which allowed the truss to rotate out from under the roadway. ---

I’m okay. Me & a friend were at an asian food store and all the lights went out. We walked to the local co-op and heard the news. It was surreal, and still is.
