A 50-car pileup snarled traffic on Interstate 35 in Ames, Iowa, causing a number of injuries but no deaths, officials said.
The crash led to the closure of the interstate on Monday.
“It’s a mess. They’re trying to get everyone to slow down,” Sgt. Nathan Ludwig told the Des Moines Register.
Mary Greeley Medical Center told WHO-TV that more than a dozen people were admitted with injuries.
Kurt Kotenberg, meteorologist with the National Weather Service in Des Moines, noted that snow likely led to the cause of the crash.
“This could be the most snow we’ve had in one single snow event in Des Doines in quite sometime,” Kotenberg told the Register. “The afternoon-evening commute could be very messy in the Des Moines metro.”
