2007: The I-35W Mississippi River bridge spanning the Mississippi River in Minneapolis collapses during the evening rush hour, killing 13 people and injuring 145. The NTSB cited a design flaw as the likely cause of the collapse, and asserted that additional weight on the bridge at the time of the collapse contributed to the catastrophic failure.
