Francis Scott Key Bridge collapse in Baltimore...

False. They rebuilt the I-35 bridge in Minneapolis in a year after it collapsed in 2007.
Mn/DOT announced on September 19, 2007, that Flatiron Constructors and Manson Construction Co. would build the replacement bridge for $234 million.[165] The I-35W Saint Anthony Falls Bridge was opened to the public on September 18, 2008, at 5 a.m.[166] Using the innovative design-build project delivery method, the replacement bridge opened over three months ahead of schedule, and was awarded the "Best Overall Design-Build Project Award" for 2009 from the Design-Build Institute of America.[167]
