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. https://youtu.be/ioC61QW7SHQ http://www.miaminewtimes.com/news/mu...ayers-10176950 |
