When an Ohio bridge buckled 12 years ago, engineers called in to investigate the scene blamed thin, corroded gusset plates on the bridge, which was overloaded with construction equipment parked on the roadway above. The findings were widely reported -- including an article entitled "Grand Gusset Failure" in the journal Civil Engineering -- but the incident was considered an anomaly, and no widespread gusset inspections were ordered by the government. Now the families of victims in the eerily similar collapse last year of I-35 in Minneapolis are asking why officials failed to learn from the earlier accident.
