CASCADE, Idaho — Editor's Note: The video above originally aired in August 2020 after a rock slide toppled a Sawtooth mountain peak.

On Thursday afternoon, parts of Highway 55 in Idaho were closed after a rockfall blocked the roadway.

According to the Idaho Transportation Department, the rockfall happened on Highway 55, between Sportsman Access and Round Valley Road, which is between 11 and 14 miles south of Cascade.

The highway is closed between milepost 97 and 100.

Drivers are urged to find and use another route until the rockfall is clear. The Idaho Transportation Department recommends using Highway 95 as an alternate route.
