I mean all of this happening in short order including the renewed upheaval in the mid east isn't accidental. May not ALL have been coordinated but when 1 thing happened there was an opportunity to take advantage and cascade.

Interesting. I haven’t thought about it that way.

Some of it I’ve just assumed is the result of poor leadership in the US.

Yes, piss poor but with every "crisis" comes opportunity and there are people who will take advantage of every opportunity.

You just have to figure out if it's our "own" people willing to sink us for a buck, or somebody else probing for weaknesses. Poor leadership makes either possible. If we back out of the ME, people aren't making money on expendables - the kind that go boom, and other people may fear they are becoming the focus if our military isn't looking elsewhere for trouble. The rest of the world would prefer to have the US as a consumer rather than a producer. At the same time nobody in the US government seems to be inclined to deal with our real problems because the problems are too polarized

MEMPHIS, Tenn. — Memphis Mayor Jim Strickland says it could be months before repairs are complete on the I-40 bridge.

Authorities closed the Hernando Desoto Bridge after an inspection found a crack that requires investigation. It’s unknown when the bridge will reopen, but on WREG’s Live at 9 Wednesday, Memphis Mayor Jim Strickland said he spoke with state leaders and TDOT Commissioner Clay Bright for about 45 minutes Tuesday evening.

Me, too, but bending near a rigid component such as a pier sure looks like a trouble point when you have cyclic loading.

Yeah. I figured it was near the end not the middle of the span. But I dont deal with this type of loading, so I am trying to keep comments pretty generic.

Almost looks like it was cut with a plasma cutter. Looks like some rust is present, wonder how long it's been like this.

That's bad, almost looks like the footing the bridge rests on has shifted or been compromised, that's side to side action. But I'm no expert.

Side to side and up and down. It's why I was thinking shear. But I think that's usually the connections. I would be interested in seeing the actual structural mumbo jumbo.

Yep, I prefer the I-55 bridge, but it's narrower as I recall, and the access on the Memphis end was developed by a bunch of mentally retarded monkeys. Of course, the whole road system through Memphis is like a zoo anyway.

It's funny you say that. The original design for I-40 in Memphis was to go through the middle of Overton Park (potentially destroying the Memphis Zoo).

MEMPHIS, Tenn. (WMC) - Barges are lining the banks of the Mississippi River due to a major bridge closure between Tennessee and Arkansas.

Officials with the Tennessee Department of Transportation flew to Memphis Wednesday to give an update on the I-40 bridge closure and noted there were several barges at a standstill.

According to the U.S. Coast Guard, there are 229 barges in the queue. Five are stopped at Meeman-Shelby Forest State Park.

Up and down is expected, even a little side to side as well. You'd be surprised to know just how much they move. I was stuck on a bridge in Nashville during the 2010 flood. Man, you could feel the sway back and forth, my apprehension was sky high.

I know it moves. Just seeing it I the failure is what makes it interesting.

The amount of movement in multilevel parking garage or on a bridge is a definite attention grabber.

Yep, shut down I40 and then shut down barge traffic on the Mississippi, couple that with the pipeline shutdown, the Israeli war... Biden is off to a stellar start to WW3.

I don't get closing the river to barge traffic. The bridge doesn't seem likely to collapse, and it could have been in this condition for months. Hopefully tug operators can still navigate without running into the piers. Just seems like the typical bureaucratic kneejerk reaction - they have to be seen as doing something - "managing the situation". Maybe they'll just paint the piers and put fancy lights on them so the tugs will be sure to miss them - or be attracted by flashy things.
