Engineering experts say investigators looking into the collapsed ‘instant’ bridge in Miami will want to know why a central tower which is usually built to support a suspension bridge was not in place when it collapsed onto Tamiami Trail on Thursday afternoon.
Last week, Florida International University’s official Twitter account posted a rendering of the bridge in its completed form as envisioned by the planners before its opening to foot traffic in early 2019.
The rendering shows a tall central column with cables connecting it to the main span.
Engineers say the design is known as a ‘cable-stayed bridge,’ which is a kind of suspension bridge, according to USA Today.

Stands for "above road, 15 minute warranty.
Design flaw. Blame the coolies and the peons.
And, Rosenberg is buddies' with both Yeb! and Crist, so I wouldn't be surprised in the least that corners were being cut in not checking for other kinds of legal requirements in the construction process as well.
Engineering Schools + Affirmative Action = Dead Motorists
Seems a lot of stupidity reigns in America these days.
Last place I was at, you could NOT turn them away from rank stupidity. It was mind-boggling. Complete rejection of truth, best practices, etc.
Yeah, that's a real head-scratcher. /s
Of course they could NOT figure out why they had problems.
I should have bought a small mirror and dropped it off.
[I’d call it criminal negligence.]
That’s exactly what it is.
No doubt.
I went to college in WNC, which is WCU, and we had/have a walk across bridge that has been there for decades. In fact, there are lots of walk across bridges, in NC, that have existed for decades with zero problems!
The engineering of those bridges were done by some great people, and if ‘a design isn’t broken, do not try to fix it.”
Barack’s broken bridge
“undocumented citizens”
Who cares as the workers don’t call the shots on protocol
That’s the innovation part of the speeded up construction technique.
My guess is that they were over confident it would have no issues, when stress tested. However, it is common sense to err on the side of caution, and at least stop traffic from going under the bridge during that test! People died from that lack of forethought....sad.
Wasn’t it just recently that various professorettes, of and without color, were asserting that long-established and held mathematical and engineering concepts were racist and sexist?
I suppose this collapse on a college campus is acceptable as long as diversity-approved design principles were employed.
Putin would blame the jews or possibly tatars. I’m still trying to figure out what a tatar is.
I didn’t think it was the fault of the design; rather, the installation. I wonder whether the design engineers provided instructions on installation I would think they did. So there may be fault there.
But this bridge used the “innovative Accelerated Bridge Construction”

That means put it up quick, before it falls down!
I would not be surprised if this project was behind schedule and somebody was pushing it to show progress—consequences be damned. Kind of like the space shuttle Challenger.
If they wanted to prefab both spans in an adjacent work yard WHILE building the tower, then close the road (for a month or two) to assemble the parts and work out the bugs, that might have made sense. They could have used cranes to lift the span up a few feet off the ground right where it had been created, and made any adjustments to post-tension reinforcement or connection details with no need to swing it over the road. Only explanation I can conceive for trying to suspend this span in midair (apparently for a while) would be that due to space constraints, they needed to use the same lay-down yard to build the second span. But there looks to be lots of desolate space on the left side of the pics where the “left” span could have been built. Much to be revealed about this.
Prelim Verdict: incompetent idiots in charge from the client to the engineers to the contractor to the highway department.
I wonder whether the design engineers provided instructions on installation

Maybe it was pictorial diagrams, like IKEA furniture.
Because that supports the white dominated patriarchy.
how well was the steel pretensioned as the concrete cured? (bowed?)
