Okay-----serve a second cake decorated like the French flag.

FWIW, just worked for me. :-)
Been checking FEC records for some of the Munilla brothers. RINO/Uniparty players, gave to local Critters, McCain, Rubio, and Bob Menendez. Haven’t found any donations to Trump so far...
Just about every over pass I see on highways and local roads have steel beams. Why the need for a cable stayed bridge for this; what should have been a mundane pedestrian footbridge? Oh, the Feds are on the hook, let’s splurge ?
“If stress testing being conducted, why would the road be open, with vehicles stopped directly under the bridge? Doesn’t make sense.”
You may find a contractual clause penalizing the company if they interrupt traffic. Interruptions to traffic probably subtract from award fee or performance fees. The site manager would say, “we need to close down traffic for two hours to conduct a stress test.” The owner/manager would see a reduction in his take-home of x dollars and say, “Can we do it without interrupting traffic?”
“Well, so long as the test is successful, yes.”
“What? You don’t trust your design? Do it without interrupting.”

You are spot on. Concrete roof indeed. The Chinese would take the company principles outside and put one between the lookers for such things.
I still mourn the dog in the car.
I think this was a pure constructor screwup.
See this video animation of the bridge:
This shows a cable-stayed bridge design. The upper stays were not in place, yet they had no temporary supports at the midpoint of the bridge until that tower on the one side was constructed and the cable stays in place. There was nothing providing necessary up force, and the bridge was simply not able to support itself.
I don’t think this had a thing to do with tweaking the tension on the post-tensioning cables/tendons. Or if it did, that was not the root of the problem.
Thanks, Liz, I’m sure we’ll keep this in mind. s/
Any bets that the replacement bridge will be a much simpler design?
One of Obama's crew?
In the article, all that speedy building and shortcuts and concrete is to keep the mayor’s phone from ringing. Hope the mayor is getting an earful now.

Yep, and all that money makes it easier for politicians and their friends to steal it. Supposedly this bridge was faster to build, but it wasn’t going to open until 2019.
Pretty bridges are an urban fad these days. Everyone wants to copy the Millennium Bridge in London. (It was pretty, but required a couple of years of re-engineering after the original crew collected their money and called it complete.) https://en.wikipedia.org/wiki/Millennium_Bridge,_London
When politicians start re-directing money and undercutting specifications, you get fiascoes like the Margaret McDermott Bridge in Dallas. (Which they didn’t bother to stress test, hiding the problems until later) https://archpaper.com/2018/01/santiago-calatravas-margaret-mcdermott-bridge-cracking-wind/
“..and self-cleaning gimmick”
I believe this was loudly bragged about. I have to wonder how many other “green building” projects are in the works that have the same feature.
“”””I’ve seen too many times engineers with no mechanical aptitude rely on software.””””””
I deal with them all the time. They have never built anything themselves. They have never touched a welder, wrench, shovel.
They only know what their computer tells them. They are taught by professors who have never touched a tool or been outside.
I had a small open structure go down in a micro burst a few years ago. They all blamed me. I explained that it was built according to the engineered specifications. Every step was inspected by engineers. It was signed off by engineers.
I told them the design was wrong and the anchor bolts were too small. I told them if they changed it a little bit the wind wouldn’t catch it so much. I was told the computer models show the roof with its funky design was capable of withstanding those winds. What did they do? Rebuilt it the exact same way.
Look, if you own a construction company, accidents are part of doing business.
I will not jump to a conclusion on that issue yet.
There’s nothing overly complicated about the bridge design, it has been commonly used for many years, and they do look cool, which is nice.
You just can’t ignore basics about how they work during the construction.
As long as the project met its minority ‘goals and quotas’, it’s difficult to see what the problem is here.
