POLK COUNTY, Iowa — The Iowa State Patrol worked to clear some of the more than 50 vehicles involved in a crash on I-80 westbound near Altoona Monday morning.

Sgt. Alex Dinkla says one person was seriously injured in the crash, which happened around 11:00 a.m. east of the east mixmaster and just before reaching Highway 65. Dinkla had originally reported to Channel 13 that one person was killed, but he later corrected that statement, saying one person suffered serious injuries.

No other reports of injuries have come in to the Iowa State Patrol.

A snow squall blowing through the metro caused slippery roads across central Iowa and law enforcement agencies responded to dozens of crashes.
