I-35W bridge was doomed from the start - By TONY KENNEDY and PAUL McENROE, Minneapolis Star Tribune
Original designers of the Interstate 35W bridge in Minneapolis likely neglected to calculate the size of key gusset plates that eventually failed, a human mistake that culminated 40 years later when 13 people died after the span collapsed, federal safety investigators have found.
They also have determined that corrosion of certain gusset plates, extreme heat and shifting piers did not contribute to the bridge's collapse on Aug. 1, 2007, according to sources with direct knowledge of the probe.------------------------------------------- posted 6:36 AM :: reference link ::
