NTSB preliminary report on the I-35W bridge collapse
The NTSB has released the preliminary report on the I-35 bridge collapse. The report is available on line at the NTSB website.
The report point out to a design or drafting error on the gusset plate design. The gusset was only half an inch thick instead of the one inch required. I think everybody should read it and reflect on the lessons we can learn.
