There was a vertical tower that suspension cables would pass through that was not yet installed. A stress test was underway at the time of the collapse questioning why traffic was allowed to pass under. Question as to why there was no center support until the suspension tower was erected. A bridge engineer had left a phone message three days earlier about cracks appearing at one end but he didn't think they were a safety concern although needing repaired. Rubio has been to the scene of the collapse.
I agree about the steel construction. The bridge was 14.2 million of a 19 million grant.
As far as I know the bridge is three separate sections placed end to end , cables are passed through and then tightened to make one structure. I don't like it because of the huge mass of concrete that is held in compression without anyway of guaranteeing the integrity of all of the concrete that I know of. There was supposed to be a tower with suspension cables supporting the span that wasn't yet in place. Additionally the diagonals from the uprights in my opinion were pointed the wrong way for transferring load. They appeared to be in compression instead of tension. One article I read noted that the company made political contributions .
