MESA COUNTY, Colo. (KKCO) -- Two people are dead in a tragic accident Thursday night.
The crash occurred in DeBeque Canyon around Interstate 70 milemarker 57 just before 9:30 p.m.
According to Colorado State Patrol, two men were heading eastbound in a 1996 Honda Civic when the driver lost control, hit a barrier and rolled. The two occupants -- a 25-year-old and a 31-year-old -- died at the scene.
CSP says one man was fully ejected from the car, and the other was partially ejected, which leads investigators to believe neither were wearing seatbelts at the time.
Debris flew across all lanes of traffic, causing two Jeep Cherokees and a pick-up truck to crash as well. CSP says it's unclear if there are other injuries.
Traffic was backed up for miles as the interstate was reduced to one lane on both sides.
The westbound lanes were cleared by 12:45 a.m., and I-70 eastbound was reopened at 3:30 a.m.
Troopers aren't sure if drugs or alcohol played a factor in the accident.
CSP investigators have identified the victims, but they are waiting to released their names until their next of kin are notified.
CORRECTION: A former version of this story stated a man and a woman were killed.
