MINNEAPOLIS --- At least four people died Wednesday evening when a Minneapolis bridge collapsed during rush hour traffic, plunging dozens of cars into the Mississippi River below. According to MarketWatch, rescuers recovered injured victims and bodies from the Interstate 35W bridge wreckage through the night. More than 20 people are still missing. Many of the drivers involved in the disaster were on their way to a Minnesota Twins baseball game at the stadium just across the 40-year-old bridge. Officials said the collapse was likely due to "structural failure." Neither foul play nor terrorism was suspected. White House Press Secretary Tony Snow acknowledged on Thursday that an inspection two years ago identified structural deficiencies in the highway bridge. The bridge was rated 50 on a scale of 120 for structural stability, the Associated Press reported. "This doesn't mean there was a risk of failure, but if an inspection report identifies deficiencies, the state is responsible for taking corrective actions," Snow said.
