An ambulance and LifeFlight helicopter respond to a truck rollover that injured two men and tied up rush-hour traffic on U-201. The accident occurred about 5. p.m. Friday just west of Redwood Road in the westbound lanes of the highway. The two men were ejected in the rollover, a Salt Lake Fire dispatcher said. The driver, David K. Davis, 28, Midvale, and Eric Holmquist, 22, South Jordan, were listed in critical and serious condition, respectively, at LDS Hospital Friday night. A third passenger, Robert Merrill, 32, American Fork, was not injured. The cause of the accident is under investigation.
