BOISE COUNTY - A 12-mile stretch of Highway 21 known as "Avalanche Alley" has reopened as of Saturday morning. That's after being closed twice last week due to dangerous avalanche conditions.

The section of highway between Grandjean Junction and Banner Summit had been closed since Tuesday night. It reopened at 9:30 a.m. Friday. However, due to avalanche activity, it was closed about five-and-a-half hours later.

Highway 21 was closed as a precaution due to recent warm temperatures and avalanche activity in the area.

These were the fifth and sixth closures on the road this avalanche season. There were eight closures last season.

During 2012's avalanche season, there were eight closures between Nov. 1 and March 31, totaling 21.5 days. A total of 50 slides tumbled down on the highway during that time, as the area saw more than 28 feet of snowfall.

Motorists are advised to check the latest road reports before heading out.
