I-35W Mississippi River bridge
The I-35W Mississippi River bridge was an eight-lane, steel truss arch bridge that carried Interstate 35W across the Mississippi River one-half mile downstream from the Saint Anthony Falls in Minneapolis, Minnesota, United States. The bridge opened in 1967 and was Minnesota's third busiest, carrying 140,000 vehicles daily. It experienced a catastrophic failure during the evening rush hour on August 1, 2007, killing 13 people and injuring 145. The NTSB cited a design flaw as the likely cause of the collapse, noting that an excessively thin gusset plate ripped along a line of rivets, and that additional weight on the bridge at the time contributed to the catastrophic failure.
