Pendleton, Oregon, Dec 31: A tour bus careened through a guardrail along an icy highway and several hundred feet down a steep embankment Sunday, killing nine people and injuring more than 20 others, authorities said.
The charter bus carrying about 40 people lost control around 10:30 a.m. on snow- and ice-covered lanes of Interstate 84 in a rural area of eastern Oregon, according to the Oregon State Police.
The bus crashed near the start of a 11.2-km section of road that winds down a hill.
The bus came to rest at the bottom of a snowy slope and landed upright, with little or no debris visible around the crash site.
More than a dozen rescue workers descended the hill and used ropes to help retrieve people from the wreckage in freezing weather.
The bus driver was among the survivors, but had not yet spoken to police because of the severity of the injuries the driver had suffered.
Lt. Greg Hastings said the bus crashed along the west end of the Blue Mountains, and west of an area called Deadman Pass.
The area is so dangerous the state transportation department published specific warnings for truck drivers, advising it had "some of the most changeable and severe weather conditions in the Northwest" and can lead to slick conditions and poor visibility.
St. Anthony Hospital in Pendleton treated 26 people from the accident, said hospital spokesman Larry Blanc. Five of those treated at St. Anthony were transported to other facilities.
I-84 is a major east-west highway through Oregon that follows the Columbia River Gorge.
Umatilla County Emergency Manager Jack Remillard said the bus was owned by Mi Joo travel in Vancouver, B.C., and state police said the bus was en route from Las Vegas to Vancouver.
A woman who answered the phone at a listing for the company confirmed with AP that it owned the bus and said it was on a tour of the Western U.S. She declined to give her name.
A bus safety website run by the U.S. Department of Transportation said Mi Joo Tour & Travel has six buses, none of which have been involved in any accidents in at least the past two years.
The bus crash was the second fatal accident on the same highway in Oregon on Sunday. A 69-year-old man died in a rollover accident about 48.3 km west of the area where the bus crashed.
A spokesman for the American Bus Association said buses carry more than 700 million passengers a year in the United States.
"The industry as a whole is a very safe industry," said Dan Ronan of the Washington, D.C.,-based group.
"There are only a handful of accidents every year. Comparatively speaking, we're the safest form of surface transportation."
The bus crash comes more than two months after another chartered tour bus in October veered off a highway in northern Arizona, killing the driver and injuring dozens of passengers who were mostly tourists from Asia and Europe.
Authorities say the driver likely had a medical episode.
