MINNEAPOLIS -- Authorities in Minneapolis now say at least seven people were killed and about 60 were injured by the rush-hour collapse of an interstate bridge.
The Interstate 35-West bridge over the Mississippi River was jammed with bumper-to-bumper traffic when it suddenly broke into huge sections. Dozens of vehicles fell 60 feet into the water.
Minneapolis Fire Chief Jim Clack says the death toll could rise.
The eight-lane bridge, a major Minneapolis artery, was in the midst of being repaired and had several lanes closed when it crumbled.
So far, officials don't suspect anything other than structural failure.
Investigators teams from the National Transportation Safety Board are headed to Minnesota. An official with the Department of Homeland Security says there's nothing to link the collapse to terrorism.
