The latest information from the Wyoming Highway Patrol indicates about 45 vehicles were involved in the crash sequences on Interstate 80 between Laramie and Cheyenne today, resulting in 27 people being transported to Cheyenne Regional Medical Center.

According to a Wyoming Highway Patrol release, 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.

A total of 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. Six of those injured were critical to serious leg or spine injuries. Wyoming Highway Patrol says 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.

Agencies that responded were the Wyoming Highway Patrol, Laramie County Sheriff's Office, Albany County Sheriff's Office,  Wyoming Office of Homeland Security, Laramie County Fire Districts 1, 2, and 10, AMR Ambulance, F.E. Warren First Responders, Wyoming National Guard First Responders, City of Laramie Fire Department, WYDOT and multiple tow companies from Cheyenne and Laramie. Joint training between all of these agencies and their dispatchers was credited for the rapid response, extrication, treatment and transport of those injured in the event.

Interstate 80 between Cheyenne and Laramie is expected to remain closed into tonight and possibly through the early morning hours of tomorrow as the investigation and cleanup continues through the evening.

Weather will hold a strong determining factor for the investigators and cleanup crews as to when Interstate 80 will be ready to reopen. Travelers can check for updates at www.wyoroad.info or by calling 1-888-WYO-ROAD (1-888-996-7623)
