Saturday marks eight years since the Interstate 35W Bridge collapsed in Minneapolis, killing 13 people and injuring 145.
Video from Chopper 5 shows the wreckage of the bridge in the minutes after the collapse on Aug. 1, 2007.
The saga began when the busy eight-lane bridge suddenly buckled on a muggy evening, sending dozens of vehicles crashing into the Mississippi River and each other and stirring ripples of worry about the nation's aging infrastructure.
Investigators blamed a design flaw that was exacerbated by extra weight from a resurfacing project.
