Just turned on the news. 35W bridge collapsed in the Mississippi River. Cars, trucks, semis.....
Fires burning, tanker trucks, at least one school bus, more than ten cars......
Just now breaking.......
Rust.
Independent investigation -— absolutely!
This link may have already been posted but I'm posting it again for anyone who's not able to read all the previous posts.
The structural engineer they have on now just shot that down. She said heat has less effect on steel and concrete than cold.
At least it's a less steep incline than it was before the original span collapsed. The height at the top really was scary for some folks. My grown daughter-in-law would get down on the back seat floor and cover her head with a wrap till we got over to the other side. Yet she flies all over the country.

All is well with my sister in law and neice.
Thanks for the prayers!!!
God bring comfort to those who are scared, suffering and lost. Thank you, Father. Amen
I bet she was disappointed. She makes me sick. So sick, I had to turn it off!
They should have done a bit of editing. Amazed that it took this long for the video to get out. If it is government video, I guess I can understand.
It may or not be an act of terror. You do have some of the more virulent Muslims there -—the somalians.
Either that or the bridge inspectors are among the dumbest.
The governor just said (on FOX) that he cannot categorically rule out terrorism.
I see. So, in other words, accepting the words of the DHS at face value when they warn us that things like, for example, bridges, are prime terrorist targets -- and then observing that they persuade police across the country to dispatch when someone is observed photographing a bridge -- or even observing a bridge -- is evidence of mental pathology.
And your qualifications as a DSM-flogger are exactly what, "doctor"?
Would I be out of line suggesting that if you... ahem, "they" don't want people to think "terrorism" when a bridge kabooms, they shouldn't keep warning us to be on the lookout for terrorists trying to make bridges go kaboom?
Oh, sheesh, why am I asking you? You've obviously got either delusions of grandeur, a "post-for-hire" gig, or, a seriously warped sense of troll-humor. Sorry I wasted your^H^H^H^H^H my time.
Now does anyone know if the names and locations of the other structurally deficient bridges is available online?
When I 1st saw this last nite, and even heard 1st thing mention of terrorism, I dismissed that theory.
These nutcases aren’t going to bother with a little bridge in the middle of the country when they haven’t brought down all the “important” places in the US. This would be like 10th-tier target.
Unless it was just some local Moslem Somalis on their own mission.
Although the rocker plates were ripped free of the pier by lateral deflection, the end placement of the kingposts indicates they rotated about their bases, displacing the tops of the piers little if at all.
On the other side, you could be right, but the tension in the cantilever trusses would come as a result of the lateral deflection, not an increase in pier to pier distance as the piers at the failure point didn’t move.
A good strong jerk along the cantilever steelwork could begin the pier deflection process, which could continue as the sidespan adjacent to it fell and kept shoving them towards the river.
Not real impressed with those piers, I don’t see much more concrete than necessary for vertical load bearing, not a lot of lateral stability there, they appear to leave that to the steelwork above.
Still, it’s clear that the triggering event initiated on the far side.
There's a big difference between a third world wooden "peasant, horse, and cart"-grade bridge, and a domestic bridge designed by expert engineers. Try driving an 18-wheeler loaded with three rolls of steel over one of those "break cadence when crossing" bridges in any manner you choose, and see if you can keep it out of the water.
Just as a note to this discussion, I remember Osama supposedly saying (right after) he WISHED he could take credit for it.
Maybe it was just so big even he was AFRAID to admit it at that point?
On the other side, you could be right, but the tension in the cantilever trusses would come as a result of the lateral deflection, not an increase in pier to pier distance as the piers at the failure point didnt move.
Ummm...huh?
I suspect that at some critical point on the bridge, the combination of age, vibration and rust and too many cement trucks caused the structure to just snap like a worn out piano string.
The fact that we do not have Palestinians dancing in the streets is pretty solid evidence that this was not a terrorist attack.
This was..... (gasp).... an... accident.
You’re not the only one who has trouble with bridges. I remember going over an open grate bridge over the Genesee River when I first learned to drive. It was terrifying and I can still hear the rumble of the tires on the metal grate.
KARE Channel 11 has streaming video at the following link, as well asThe Bridge Collapse caught on Video ^
It gets pretty busy, but eventually loads.
