One man was dead and two others were recovering from serious injuries Wednesday, the day after a head-on collision with a coal-hauling semi-trailer truck in Spanish Fork Canyon.

Utah Highway Patrol Sgt. Todd Royce said that 19-year-old Arik Mack of Mapleton was driving a Honda Element SUV at 3:19 p.m. Tuesday on eastbound US-6 when it inexplicably crossed the center line and collided with the semi.

The crash, near the highway's Covered Bridge exit, caused the semi to overturn, spilling its two-trailer load onto the roadway. Troopers were unable to reopen the highway until late Tuesday night due to the extensive wreckage and debris cleanup.

Mack, who was ejected from his vehicle, was dead at the scene.

The driver and a passenger in the semi were taken to area hospitals with serious injuries.

A passenger in a third car, which sustained minor damage in the accident, was treated for non-life threatening injuries.
