Here is a foreshortened view of the Kinzua Viaduct Skywalk, showing the twisted wreckage of the towers that were toppled during the July 2003 tornado that whipped through the Kinzua Gorge. The decision to leave the debris on the valley floor was a wise one, I think, as it serves to illustrate what the forces of nature can do. It took thirty seconds ~ almost incomprehensible. The question arises: had they placed a heavy train on the bridge when bad weather was imminent, would the structure have withstood it? This has been a time-honored expedient, but in this case, there was no time. And as the bridge was being refurbished when the twister struck, that wasn’t an option anyway.
