At least twenty-seven people are being treated for injuries after three massive pile-ups on Interstate 80 between Laramie and Cheyenne Thursday morning.
The Wyoming Highway Patrol estimates 45 vehicles were involved in the crashes. Both directions of I-80 have been closed indefinitely while the crashes are investigated.
Six to ten inches of snow fell overnight in the area according to the National Weather Service and the Highway Patrol reports ongoing blizzard conditions.
Cheyenne Regional Hospital spokeswoman Kathy Baker says all hands are on deck to take in the injured.
"We have people who are going to make sure the ED [emergency department] has everything they need," she said. "We have first responders calling in to our emergency department."
Photos of the wreck show semis and smaller cars piled up on the road and in the ditches. No fatalities have been reported.
