The deck itself is 890 ft. above the ground and one of the masts is 1,125 ft above the base.
If stress testing being conducted, why would the road be open, with vehicles stopped directly under the bridge? Doesn’t make sense.
I read that they were also maybe adjusting cables that were slack, suggesting the bridge was shifting or changing?
I read a bit ago that Little Rubio is out defending the Munilla family that built the deadly bridge. How much money (and bribes) did he get?
Should the state now rush out and ban murderous walk bridges? Maybe ban construction and bridge associations? Hey, is Munilla family company a member of some racist chamber of commerce or other group? Maybe ban them.
My guess is it was due to substandard materials that were tested beyond their capacity, lead to load failure and collapse.
A high quality bridge should have been able to withstand the stress test and perform to rated limits and beyond.
I don’t think it was an accident; it was a feature.
The uni had made it clear that it wanted something pretty. Qs: Is concrete cheaper than steel? And if federal funds were used to pay for this thing, why didn't the feds have a cow about the design?
My first thought Chinese steel. Probably not the case.
Chinese concrete?
Did the order to bring it down come from McCAbe,
Clinton, Obama, Clowns, Hogg, Ohr or Strzok?
Should have been made out of US steel.
The bridge should have been strong enough to handle a full load of drunken college students, jumping up and down to see what happens.
The bridge was to be a “cable stayed” design. Look at the collapse pictures and you can see the bolts where the support cables were to attach coming down from a tower not yet erected. They were pulling “post tension” cables that run through the concrete at the time of the collapse. The cable pulling apparatus can be seen in the photos. These companies (the designers and builders) F-ed up big time and it isn’t the first or even the second collapse they have had during construction of a bridge such as this.
I was designing special effects for a theme park. An engineer was adding a themed fiberglass panel to a door with 1 inch bolts all over the place. So I asked him why, he told me it was what the engineering calcs software called for.
I told him that a trailer hitch has one 5/8 bolt.

I'm not an engineer, but I hadn't seen much like it either. When I first saw photos of the collapsed bridge along with the renderings of that it would look like when completed, I concluded that the architects/engineers had attempted to make a concrete beam with the wrong proportions... this based on what I have read of Victorian cast iron beam designs and modes of failure.
Maybe the schools stopped teaching about empirical dead white guy engineering and the school of hard knocks vis-a-vis brittle materials and tension/compression (Dee Bridge, etc).
I’m going to take an early guess and figure it’s a combination of poor or degraded material and poor workmanship
“Let’s wait until cars are stopped right beneath the bridge before we perform the stress test.”
A local media outlet reported last night that there was at least one employee of FDOT on site at the time of the accident.
What did FDOT know and what did it approve /sign off on?
It was stressed, all right. Was the concrete inferior, too, or just the design?
“perhaps too early, just looking at possibilities.”
It took months for the roadside build of the now-failed span.
Wondering here if any delays or errors that could have resulted from Hurricane Irma may have contributed to the failure.
Obviously if a center bent had been used the bridge would have been much cheaper and several people still alive today!
This was the wrong project to experiment with “prestessed concrete truss bridge superstructures!
