A section of Idaho Highway 21 is closed following an avalanche Sunday that caused slides up to 40 feet deep. The Idaho Transportation Department announced that the stretch of highway between Grandjean and Banner Summit is closed “until further notice.

A large avalanche has closed a section of a central Idaho highway, and officials say the road will remain closed "until further notice" until the massive amounts of snow are removed and conditions are determined to be safe for drivers.

Crews in Idaho are working to reopen State Highway 21 in Central Idaho after a massive avalanche buried it over the weekend.

After what officials called an “intense and relentless search” for the missing 14-year-old snowmobiler, search and rescue teams from multiple agencies found the boy at around 9 a.m. Sunday morning.

The boy was rescued nearly 24 hours after he was reported missing amid freezing temperatures, authorities said
