Government construction engineering expert witnesses told the National Transportation Safety Board last week that the underlying cause of the collapse of the Interstate
35W bridge in Minneapolis on Aug. 1, 2007, was the gusset
plates that were supposed to hold together the bridge's steel beams. The disaster that killed 13 people and injured 145 appears to have been caused by an unusual load of construction equipment stockpiled for a repaving project and errors in the original design of the
joints called gussett plates.
Bruce Magladry, the NTSB's director of the Office of Highway Safety stated that "Had the gusset plates been properly sized, this bridge would still be there."
