SALT LAKE CITY — One driver was killed in a fiery Wednesday morning crash on I-215.

The accident happened just after 2:30 a.m. on I-215 south near 100 West. For an unknown reason, an eastbound vehicle drifted off the road, drove between the cement rails that divide east and west traffic and smashed into the concrete pillar of an overpass used by UTA TRAX trains.

"I've never seen anything like this. If you look at the gap, the car barely fits down the center of that rail," said Utah Highway Patrol Lt. Mike Loveland.

There were no witnesses to the actual crash, Loveland said. But shortly after the accident, witnesses came upon the vehicle and noticed it was on fire.

"At some point after the crash there was a fire," Loveland said. "Ultimately, the car did become fully engulfed and we basically lost the entire car with the flames. (Witnesses) really just could not do anything at that point."

Black soot from the flames could still be seen reaching the top of the overpass Wednesday morning. After emergency crews put out the fire, Loveland said firefighters found a body in the driver's seat. He believed the driver likely was killed by the impact of the collision and not the fire. As of Wednesday morning, it was undetermined if the driver was a male or female.

Officials were still attempting to confirm the driver's identity Wednesday morning. The car was registered out of Rock Springs, Wyo., Loveland said.
