Looking at the current news coverage, and some of the photos and "artist renditions" of the design for the finished projectt, it seems the vertical support structure (looking like a ships mast with lines down to the flat segments) was not installed yet. If I am mistaken, perhaps someone in the area can confirm or deny this assumption on my part?

If so, then this should never have been installed without additional (temporary) vertical supports until that all important superstructure was installed.


So a suspension bridge? And they built the support structure last?

That’s some serious lowest bidder # if true.


That's what it looks like to me. They placed the bridge deck over the road first over last weekend. But, the suspension superstructure looks like it is not there. Even in the photos of the collapsed bridge, you can see the suspension cable mounts on the top of the roof with nothing attached at all.



Hopefully all the appropriate heads will roll when the dust settles if this was as easily avoidable as it sounds.


They should have placed a temporary vertical support beneath the center (blocking off the middle lane of the roadway below) to help distribute the weight from the center of the deck. Once the suspension superstructure goes into place, you remove that temporary support underneath.

If this was that avoidable, and was done to "unveil it" early for University "political reasons" and PR, then those that made the decision to implement in this manner should be held accountable for these needless deaths.

Aww.

That sucks.

Of course, but even considered, the masts on a suspension bridge need to be erected first, as they’d be holding the structure up even before the concrete is poured on the walkway.

I pray that many make it out.

I wonder if it had to do with the new type of concrete they used.

Some type of self cleaning concrete.

Q in various opinions on how to make things safer and additions to ban list.

btw Are we sure no one shot that bridge?

Oh don't get me wrong I totally agree with you on that point. However, if pressured to "open the bridge" early (since it was not scheduled to be completed until next YEAR), then this is when disasters happen. Yet, they place the deck first???? There is no engineering reason for doing that, none. There is, however, many political and monetary reasons (i.e. keeping it funded) to do it in this order.

According to a police interview a 'stress test' was 'under way' during the collapse.

Wow. I can hardly believe that.

Looking for more info - the info came from a ABC News Live reporter.

This, I highly doubt. There is no way any sane person would perform this type of "stress test" on a bridge, on site, with live traffic flowing below the test. Those are done, off site, with a myriad of sensors and high-speed cameras to capture any deflections or other behaviors. Unless of course, this is the year 1800.

That they would do something so stupid frightens me.

The bridge was constructed using an innovative approach to bridge construction – a technique meant to reduce potential risks to workers, commuters and pedestrians and prevented traffic tie-ups in the area.


What irony.

Wondering about the engineering.

Seems they did not understand the principle of testing.

potential risks

testing

workers - fail
commuters - fail
pedestrians - fail
traffic tie-ups - fail

Stress test without a controlled environment to protect people and property.

I agree. I can't even begin to understand why someone would say this - BUT - it was reported the 'test teams' (I forgot their ABC name)? Many of that team was on site before the collapse.

I'm not so much believing what's being said but I think it's good to get this stuff recorded while it happens in case (when) the 'facts' mysteriously change later.

Like the Commanding Officer is saying now - do not report any information that doesn't come from me/us. On the other hand when someone pans a camera to focus on 'stress team' members and names cause of the incident?

I'll hold off until after the investigation is complete. I can think of a hundred different things that could have caused this.

I have a feeling this will be one of those cases future engineers learn about in class.

Wow ..........new bridge and it collapsed. Thoughts and prayers for those involved.
I can't believe reporters are dumb enough to ask what caused it........ok I can believe they are dumb enough
.

I found this www.msn.com... It shows how this ABC (accelerated bridge construction) was built.

Nowadays, the word investigation actually means cover up.
