This is interesting.

I was puzzled by the odd angling of the zigzag cross bracing in the bridge
and once you see *why* they zig and zag like that, the reason it failed
becomes a bit clearer.

In essence, the bridge is actually a cable-stayed design, but the deck
*should* have been strong enough to be self supporting until the support
cables were installed.

If you fast forward to 7:33 you can seen what the finished bridge should
have looked like.

The political stuff is boring, but this shows an asymmetric cable stayed
bridge at least somewhat similar to the failed one.
