#1 Thanks Frank but it is not from me. It is from a State Inspector I live with.

"The failure was in the concrete itself and has nothing to do with the supports at each end. concrete crack / failure - possible at a 'seam' where the concrete was poured in segments - not sure what was happening within the concrete - but it was a transverse fracture - the key was looking at the support that is standing - by itself. it happened at the other end "

#2 Poor quality reinforcing steel? Three bag concrete mix ?

#4 Doesn't the concrete need to be tested? Perhaps something wrong with the "pre-stressed" cables?

#5 Both items you mention probably Chinese in origin, Besoeker.

There's been huge issues with ChiCom 'Portland' cement that has flooded some markets. I'd be looking there first.

#7 #1 - With all due respect, that's utter bullshit. Concrete in shear is resisted by the reinforcing, not concrete shear strength with at least a factor of safety of 1.5 and more likely 2 or higher. Pour joints don't mean squat and in any event they'd have keyways and extra reinforcing at any joint. Your State Inspector needs edumacating

#8 But then, I've only been doing bridges and structures for 35 yrs, so what the hell do I know?

#10 Excellent reputation

#11 Um, the Pantheon is made of UNreinforced concrete and has been standing for 2000 years. Seems to be a problem with modern technology......or more likely modern financing aka greed.

Will be very interested to see how much of this is covered up. BTW anyone hear anything about that Vegas shooting?

#12 The main ingredient is probably Dade County corruption.

My thoughts exactly. The construction company has a few other issues in their past as well and yet go the bid anyway.

#16 The Daily Mail has security camera video of the the bridge collapsing here. Perhaps that will provide useful information.

#17 Amazing video, that one car stopped just in time.

#18 More linkies and some video via NeverYetMelted.
Interesting bits: The bridge is also made of self-cleaning concrete. When exposed to sunlight, titanium dioxide in the concrete traps pollutants and turns them a bright white, the university said.

Referring to the modular construction and Inadvertent Snark of the Day:
Saturday installation marks the first time a bridge this large has been installed in this way.

#19 Fault lies with the Fly Ash Liberation Army. Ask Commodore Frank, he knows........

#20 yep or bad tensioning/tensioning design...more likely

#21 It's supposed to be a suspension design. This is the first time I've seen the suspension wasn't built first. It's crazy that the supported section was left without support.

#22 The bridge is also made of self-cleaning concrete.

Maybe someone read this wrong and built it out of self-destructing concrete instead.
