A massive, near 40-foot deep avalanche blocked Idaho’s SH-21 between Grandjean and Banner Summit on Sunday, February 9. The roadway is currently closed from milepost 93.7 to 105.5.
According to the Idaho Transportation Department, crews have been working to clear the slide, which reaches about 40 feet deep along the road.
