VIDEOS: A dust storm in central Illinois led to a pile-up crash of more than 70 cars that killed six people and injured more than 30 others Monday.
Crushed vehicles lined the expressway south of Springfield, closing a nearly 20-mile stretch of I-55.
Authorities continued to work to clear that stretch of the expressway, which they said was back open to traffic shortly after 6 a.m. Tuesday.
Illinois State Police have released the identity of one victim, 88-year-old Shirley Harper of Franklin, Wisconsin. Police said three other people have been identified, but their names have not yet been released. Two of the people identified were from Champaign, Illinois and one was from Florissant, Missouri.
A total of 72 cars crashed into each other, with drivers describing the burned and mangled metal as surreal.
