The firm was the designer of the ill-fated I-35W Mississippi River bridge, Minneapolis, Minnesota, 1964 (collapsed on August 1, 2007).[1] The official report by the National Transportation Safety Board blamed the bridge collapse on a design error by the firm, resulting in the gusset plates having inadequate load capacity.[2]
