When the pedestrian bridge collapsed last week in Florida, workers were adjusting tension on the two tensioning rods located in the diagonal member at the north end of the span. That’s one of the findings of the National Transportation Safety Board (NTSB) team that is investigating the incident, which crushed cars and killed at least six people - one of them a bridge worker.
Workers had performed this same work earlier at the south end, moved to the north side, and had adjusted one rod. They were working on the second rod when the span failed and collapsed. The roadway was not closed while this work was being performed.
