Why the Bridge Fell
The Star Tribune reported on Friday the results of the NTSB's bridge report.
According the the Star Tribune, the bridge was heavily loaded with construction equipment, equivalent to the weight of a 747 airplane.
The National Transportation Safety Board officially decided at the end of a two-day hearing that the 35W bridge collapsed because of faulty gusset plates the Pioneer Press said.
According to the Pioneer Press, the gusset plates were too thin by half, a fault of the engineering firm that designed the bridge.
