The deadly collapse of a bridge in Genoa, Italy, last month set off a bitter debate about who bears responsibility for the disaster and precisely what caused it. “It was not possible to save the bridge, but maybe it was possible to save the persons who died in the collapse,” said Carmelo Gentile, a structural engineering professor at the Politecnico di Milano. When the bridge — a signature of the port city, a source of deep civic pride, and an indispensable daily transportation link — was built in the 1960s, Genoa’s viaduct was more than just a bridge. It was a 3,600-foot journey of artistry and innovation that had garnered its designer, Riccardo Morandi, fame. Its figure was so light and airy it seemed to have leapt from an elegant line drawing on an engineer’s gridded pad to where it soared over Genoa’s deep, rolling valleys. Its beauty was its simplicity. But engineers gradually recognized that the structure had so few crucial supports that if even one of them failed, an entire section could collapse. @ニューヨーク・タイムズ has recreated what happened by using investigators’ descriptions of a central piece of evidence — video footage captured by a security camera.
