WaPo illustration:



Looks like it should have had temporary supports until they built the suspension structure.  Looks like they forgot that part.
Yep.

I think the truss sort of thingy was just architectural except that it carried the line of the suspension cables down to the lower deck. That's why the odd angles of the struts.
Are we there yet?

Yeah.  Looking at the video, it looks like the failure occured at the point at deck level that should have been supported by the first cable on the from the mast.

Yep, you can see it buckling there.

Somebody is going to get in a lot of trouble. This was a completely avoidable event. The dead load of the structure was massive, I mean, how many people were going to be on it at one time, maybe a 100 or even 200. That's perhaps 20 tons vs the 960 tons dead load and would have made no difference. They shouldn't even have put it up without bracing supports unless they had the cables installed. They didn't even have the mast for the cables built much less the cables available. It's actually surprising the bugger didn't collapse right off.

More armchair enginerding.

Seems failure may have occured during post-tensioning.

With piccies of proposed smoking gun.

Obs an Obama deep-state black-flag operation to take all our guns.
