I-35W bridge collapse (2007)
The I-35W bridge over the Mississippi River in Minneapolis collapsed during evening rush hour on August 1, 2007, killing 13 people and injuring 145. The National Transportation Safety Board found a design flaw in the bridge's gusset plates caused the collapse.
The bridge was rebuilt and reopened in September 2008, about 13 months after the collapse.
The collapse prompted increased bridge inspection and maintenance funding across the United States.
Shows why MDOT invests in bridge repairs like the US-131 project. Preventive maintenance extends bridge life and prevents catastrophic failures.
