The large crane was lifting on the bridge. You can even see the cable snap upward when the bridge came down. The witness said they moved it out of the way afterwards.

Rubio: "The cables that suspend the bridge had loosened" [View all] dalton99a Mar 2018 OP

So something had gone wrong within hours of installation Demovictory9 Mar 2018 #1

A 175' suspension pedestrian bridge in an area prone to hurricanes. What the fuck were they thinking? TheBlackAdder Mar 2018 #10

It was designed to withstand a cat5 hurricane. So they knew what they were thinking. Blue_Adept Mar 2018 #15

I head that NWS is establishing a new Cat 6 :) mchill Mar 2018 #26

Definitely a necessity in the state of things. Blue_Adept Mar 2018 #30

I doubt that. Tipperary Mar 2018 #47

Wouldn't it be smart to search before saying that? Blue_Adept Mar 2018 #49

Better to drop the stupid Categories altogether Mariana Mar 2018 #52

Rubio, an adjunct professor there, said it was a new and innovative design. ie. Never tested before. TheBlackAdder Mar 2018 #33

Is he a professor of engineering? Retrograde Mar 2018 #34

He's a prof of Graft and Kickbacks, which might make him qualified as a building code inspector. TheBlackAdder Mar 2018 #36

Yet somehow it didn't withstand even in the normal weather. LisaL Mar 2018 #45

Oh, we know weather is what caused it? Blue_Adept Mar 2018 #46

Yet it could not withstand a 5 mph wind Generic Brad Mar 2018 #48

Ah, then we learned officially that it was a 5mph breeze that caused it? Blue_Adept Mar 2018 #50

Just being snarky Generic Brad Mar 2018 #53

Skyway bridge. NCTraveler Mar 2018 #22

Manaford was involved somehow tool. Demsrule86 Mar 2018 #17

Last year Manafort was hepling a Chinese company take over the bridge builder csziggy Mar 2018 #41

Now, hubs company had parts made of Chinese steel...shitty steel...they had to scrap them and have Demsrule86 Mar 2018 #44

This is a funny response ProudLib72 Mar 2018 #2

Thanks! I wondered if there was any pushback... Rhiannon12866 Mar 2018 #6

Does Marco have any reason to MontanaMama Mar 2018 #12

If they were concerned about the bridge exboyfil Mar 2018 #3

Exactly. LisaM Mar 2018 #5

Post tension cables samir.g Mar 2018 #4

So they were securing the pedestrian bridge while allowing vehicles to ride underneath it? TheBlackAdder Mar 2018 #7

I suspect they had an institutional animus against shutting down traffic... Rollo Mar 2018 #9

Back in the early 2000s Retrograde Mar 2018 #35

Must have been this one... Rollo Mar 2018 #42

or this... Rollo Mar 2018 #43

There's got to be more to it than that... Rollo Mar 2018 #8

Other possibilities include substandard materials, improper assembly, or just plain bad design... TheBlackAdder Mar 2018 #11

Wouldn't be surprised. I recall well the Boston tunnel wherein the huge ceiling tiles RKP5637 Mar 2018 #28

This is the best article I've found so far, with actual engineers commenting muriel_volestrangler Mar 2018 #14

Good article. I would bet that the span was self-supporting with only a low margin of safety FarCenter Mar 2018 #24

They could probably build a temporary bridge or pontoon across the canal muriel_volestrangler Mar 2018 #25

Or maybe the walkway breaks at the point where the first two angled members meet it FarCenter Mar 2018 #29

could they have over-tightened the cables - perhaps to the point of breaking? DrDan Mar 2018 #23

Why didn't they block traffic while it was being done? Cattledog Mar 2018 #13

It's vitally important to know exactly what went wrong, but... Girard442 Mar 2018 #16

What cables? The central tower and the stay cables had not yet been erected. FarCenter Mar 2018 #18

I think they are referring to the post-tension cables - they run through the center of the concrete DrDan Mar 2018 #20

EXACTLY MY RESPONSE WHEN I READ HIS TWEET. The entire superstructure bullwinkle428 Mar 2018 #21

fuck this idiot, I'll wait for the investigation is completely before I listen to someone Javaman Mar 2018 #19

My best guess Alea Mar 2018 #27

That big ass crane arrived post collapse Brother Buzz Mar 2018 #37

You should watch the video of the collapse Alea Mar 2018 #38

The bridge looks like slabs of unreinforced concrete Demovictory9 Mar 2018 #39

i saw planned pictures compared to state of bridge just prior to collapse bdtrppr6 Mar 2018 #31

Rubio, . . . intended to be an an innovative and one-of-a-kind engineering design. TheBlackAdder Mar 2018 #32

And RUBIO has dibs on an expert opinion about anything from guns to bridges: be-CAUSE ?!1 UTUSN Mar 2018 #40
