A West Valley man was crushed to death when a load shifted on the tractor-trailer rig he was driving as he tried to avoid a collision.

Steven Cox, 34, 4046 Westlake Ave., was driving the semitrailer truck north on Redwood Road when the driver of a compact car attempted to make a left turn onto 41st South at the intersection. The two vehicles collided, West Valley Police Sgt. Kelly Davis said.When Cox braked, a 105-foot long concret support the tractor was pulling slid forward, pinning Cox in the cab. The 170,000-pound beam was to be used in construction of an I-215 freeway bridge, Davis said.

"He made a quick stop, which caused the load to shift forward. It pinned him in the cab," Davis said. "The support slid into the semi-tractor, crushing him."

Emergency crews had to use a crane to remove the concrete beam from the truck's cab. Cox was transported to Pioneer Valley Hospital, where he was pronounced dead.

William Robinson, 57, Salt Lake City, who was driving a secondary steering unit supporting one end of the beam, suffered only minor injuries, Jarvis said.

The car's driver, Carla A. Lindh, 22, 3810 S. Redwood Road, suffered minor injuries.
