A Greyhound bus overturned in the median of icy I-70, injuring 15 people, including three children, authorities said Friday.

The 14 passengers, at least three of whom were Utahns, and the bus driver were taken to St. Mary's Hospital in Grand Junction, where six were being treated for broken ribs or other fractures, Colorado State Patrol spokesman Gordon Smith said. None of the injuries was considered life-threatening."We have no critical injuries whatsoever," said a nursing supervisor.

At least three Utahns were among those injured. There were: Mike Perry, Riverton, 42, rib fractures; Donald Keener, Salt Lake City, 43, general muscle strain; and Michael Goodrich, 39, Sandy, fractured ribs and spine. All were listed in stable condition at St. Mary's Hospital in Grand Junction.

The other victims were thought to have minor injuries and were taken to the hospital only for observation, Smith said.

The complete list of passengers was unavailable late Friday, the patrol said.

The bus was traveling west from Grand Junction to Green River, Emery County, on I-70 when the accident occurred about 15 miles west of Grand Junction and a half-mile west of Loma about 4:40 p.m., Smith said.
