Joshua Scheer posted this video to his YouTube page of Thursday's pile up on Interstate 80 near the Harriman Road exit between Cheyenne and Laramie.

33 commercial vehicles and 12 passenger vehicles were involved.

16 motorists were transported by ambulance and 11 were transported with less serious injuries by bus. Six people are reported to be in serious condition with leg or spine injuries at the Cheyenne Regional Medical Center.

Interstate 80 between Laramie and Cheyenne remains closed Friday morning and according to WYDOT travelers should expect more of a delay with cleanup and more winter weather.
