Two years ago, during the Wednesday evening rush hour in Minneapolis on August 1, the I-35W bridge over the Mississippi River collapsed, killing 13 people and injuring 145. Have we learned any lessons from this tragedy that help make us safer today? Regrettably, the answer is no.

The National Transportation Safety Board hearing into the collapse of the Interstate 35W bridge - NTSB investigators have found the weight of the bridge and construction materials and equipment placed on it forced a poorly-designed and under-sized gusset to fail.
