ITD to Close 'Avalanche Alley' Again

Posted By on Fri, Feb 7, 2014 at 11:35 AM

Idaho's "Avalanche Alley" is set to be closed later today, the second time the stretch of state Highway 21 has been closed due to weather this season. The road was closed through much of the weekend of Jan. 10-12 after snow slides.

The Idaho Transportation Department announced earlier today that the 12-mile stretch of Idaho 21 between the Grandjean Junction and Banner Summit would be closed as an avalanche-safety precaution, beginning at 6 p.m. Feb. 7. The area received more than eight inches of snow overnight and heavy snowfall is expected to continue through much of the weekend.

"Avalanche Alley" accounts for 90 percent of avalanches on Gem State highways. ITD reports an average of 45-50 slides each year and more than 250 inches of snow on average.
