The Wyoming Highway Patrol (WHP) has confirmed that three people lost their lives in a collision near Cheyenne on Friday morning.

The crash occurred around 1:20 a.m. on June 17 on I-80 at mile marker 383, east of Cheyenne, Wyoming.

“The preliminary investigation shows a commercial truck and trailer headed east on Interstate 80 around milepost 383. The tractor-trailer driver lost control, causing the truck and trailer to roll over and stop in the roadway. A second commercial tractor and trailer also headed east collided with the overturned commercial truck, and both vehicles immediately became engulfed in flames. The make and models of both commercial trucks are still being investigated due to intense fire,” WHP said in a Friday afternoon news release.

Three fatalities were confirmed, but troopers are still investigating the identities of the deceased.

WHP advises that the eastbound lanes of I-80 will remain closed from milepost 370 to 386 for most of Friday while the investigation and clean-up occur. All eastbound traffic in this area has been re-routed to the I-80 Frontage Road.
