A San Juan County employee was killed when the massive dump truck he was driving soared off a bridge and crashed into a creek bank. A West Valley man died when hit by a car while in-line skating Tuesday.

Killed were:Donald B. Lyman, 22, Blanding.

Miguel Ferron, 18, West Valley City.

- Lyman was hauling a load of road-resurfacing mix east on U-262, 15 miles east of Blanding. He took out several feet of guard rail and a portion of the bridge before it crashed through the bridge on the right side, Utah Highway Patrol Sgt. Douglas Hall said.

The 46,000-pound truck flew 60 feet before it slammed into the bank. After impact, it overturned once and crushed the cab.

"Even though the driver had his seat belt on, he didn't have a chance because the cab was obliterated," Hall said.

The truck landed 14 feet below the bridge on a flat portion of the bank. That's why it didn't roll farther, Hall added.

Troopers aren't sure what caused the crash and are still investigating.

- Ferron was heading south on 2200 West about 4600 South when he skated in front of a sports utility vehicle about 6:30 p.m., Salt Lake County Sheriff's Lt. Wally Gray said. Ferron died at the scene.

"Witnesses said he just darted out in front of a vehicle, also heading south," Gray said. "There was no speed involved or any fault on the driver's part."
