I-35W over Mississippi RiverMinneapolis, Minnesota
Interstate 35 splits through the Twin Cites, I-35E serves St. Paul and I-35W runs through Minneapolis. The I-35W bridge over the Mississippi River collapsed on August 1, 2007. 13 people died and the bridge was out of service for over a year, reopening in September of 2008. A design flaw in the original construction was determined to be the cause.
