Icy conditions caused dozens of accidents on the highways in the Rocky Mountain foothills today, injuring at least five people and causing authorities to temporarily close a 90-mile stretch of Interstate 80.

At least 110 accidents, including some rollovers, were reported from midnight Saturday to this morning, the Wyoming Highway Patrol said. A 9-year-old girl was killed in an accident in western Nebraska.

One crash in Wyoming involved 12 semitrailers and six cars. The ice was left behind by the remnants of a major storm that dumped at least a foot of snow in the central and western mountains overnight.

The injured were taken to area hospitals. Four people had to be extricated from their vehicles, said Wyoming Highway Patrol Sgt. Stephen Townsend.

Authorities closed the eastbound lanes from Sinclair to Laramie by late morning, and reopened them in the afternoon. Traffic had to be escorted to Laramie on U.S. 30 in groups of 100 vehicles, Townsend said.

Icy conditions also caused a rented van loaded with Rocky Mountain College junior varsity basketball team members to slide off Interstate 25 north of Casper on Saturday night.

The van rolled onto its side and team members suffered minor injuries. A coach cracked his ribs and one player had a broken collarbone.
