After seeing a lot of confused nonsense on national media I found an intelligent discussion of the Miami pedestrian bridge collapse, over on Welding Web.
A photo of the model shows the weight will be carried by cables - from a central tower that was going to be built after the decks were placed.
And a post saying the failure came after the post-stress rods (cables?) were re-tightened. One theory is that a rod snapped during re-tightening.
I haven't seen a rational, engineering-based explanation like this anywhere else yet. There seem to be contributors with an engineering background posting in that thread.
Miami pedestrian bridge installed on Saturday. Collapsed today.
