A middle-aged man was killed in a rollover Thursday about 9:30 a.m. when his car slid off a westbound lane of U-201 after crossing the overpass at 32nd West. Utah Highway Patrol Trooper Ben Lang said the driver was not wearing a seat belt, and the car rolled down the north side of the bridge embankment. Scott Langford, a witness, said the man was partly ejected and was pinned under the vehicle. "I got underneath and tried talking to him," Langford said. Rescue teams had to lift the vehicle before they could pull the man free of the wreck. The man's identity had not been released at press time.
