Abstract
On August 1, 2007, four of the eight lanes of Minnesota’s I-35W highway bridge were closed to accommodate roadbed repairs. Evening rush-hour traffic was diverted into the four open lanes, creating an asymmetrical stress that compounded an underlying weakness in the bridge’s support system. When the center span collapsed, 17 of the 111 vehicles on the bridge were cast into the Mississippi River, 108 feet below, killing 13 people and injuring 145 (fig. 1-1).1
