So final number dead was 13 I guess, but yesterday some interesting stuff was announced:
"Investigators have found 16 fractured gusset plates from the center section of the steel-deck truss bridge...."
"Basically, those 16 gusset plates were too thin to provide the margin of safety expected in a properly designed bridge such as this," Rosenker said. "These gusset plates were roughly half the thickness that would be required -- half an inch thick rather than an inch thick."
