33 commercial vehicles and 12 passenger vehicles is the latest estimate that were involved in one of the three crash sequences along with multiple other vehicles that were not part of an actual crash, but became stranded in the event due to road blockage. 16 motorists were transported by ambulance and 11 motorists were transported by a Laramie County School District bus to Cheyenne Regional Medical Center in Cheyenne, Wyoming. Six of those injured were critical to serious leg or spine injuries. No fatalities were reported from this event.

Speeds too fast for the blizzard conditions and loss of control are being investigated as contributing factors in the crashes that caused a "domino" style chain reaction after the first couple of vehicles lost control.

Interstate 80 remains closed between Cheyenne and Laramie as the Wyoming Highway Patrol and agencies from two counties respond to three major pileups near Granite Canon because of the storm Thursday.

Vehicles not involved in the crashes are being cleared from the crash scene at this time.
