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.......
Ummmm.....that would be a cluster......
;-)
LOL. Thinking of Jesse reminds me of Barbara Carlson. Remember Jesse & Barbara’s show? What a hoot.
We've got a strong team...Jason Lewis...Jason Lewis...Jason Lewis...
Ready to contribute, ready to fight for what's best for this country...Jason Lewis...Jason Lewis...Jason Lewis...

One lesson that has to be learned from past experiences is that erosion is not a linear-rate process. Unfortunately, many engineers have not learned that simple geologic fact, from channel erosion to beach loss.
That being said, I don't think there's much evidence that caisson/pier failure was involved in this case, and I certainly don't know the qualifications of the MnDOT inspectors.
Sometimes that drives me crazy! C’mon Jason, change is good. :)
That shouldn't be a problem, even if they were off to the side, because that would be where 18 wheelers of the same weight would pass in line regularly.
"Looking at the videos its just a bit strange how it fell, more like a controlled demolition. I would ask some of those demolition experts if it could be done without using explosives.
One of the truss members, or connection, around the SE pier failed. That caused the roadbed to tilt down, drop, pop at all the bearing points, and drop straight down. The rest of the road bed followed as a rigid sheet (road bed + superstructure, straight down). I can't find the SE king post in the rubble. The SW one tiddly winked out and off it's pile intact. You could ID different truss members, or supports on the SE side which are critical. What's important though was for someone to do that before this happened and recognize that something was wrong in that area. The steel there was already failing and had strained to a point, that the bearings in the expansion joint were taking up unnatural stress. That's why a normal load triggered a catastrophe.
As far as a man made "crack" goes, the investigators that have the broken pieces in hand and can see how it all fell, could spot that right away. They probably already know why the bridge fell. They won't release that until they reconstruct the whole thing on paper, instead of envelopes and go over it a few times.
Barbara, well "I" think" Carlson?
Is she still in treatment?
I sure like that show!
Exactly... regardless of names or route numbers, the shame is that there are many existing bridges that aren't built how they would be if they were created today.
I guess he just doesn't consider himself a "progressive". ; )
Praise God!
I agree your analysis sounds reasonable.
I just moved to Minneapolis, and was first out househunting, then couldn't get internet access at the hotel.
I used to drive over that bridge all the time when I attended the U.
Prayers UP!
That's because he's wrong even less of the time than I am. /snicker
Oh, and let’s not forget Bab’s son.....Tucker Carlson
Is that POSSIBLE? ;-)
Really?? Do you listen on the web??
Wait a minute...not the Tucker Carlson with the bowtie? O-M-G....
8th wonder....
ROTF!
I think it’s more than that. Don’t you have some liberal friends around here that, while you can’t agree on politics, you can discuss them with civility, and otherwise get along fine?
Yep........
