An 800-pound boulder fell from the side of the road onto Interstate 80 in Sierra County on Sunday, holding up traffic for about 30 minutes until it could be moved.
The boulder impeded traffic at about 12:30 p.m. when it fell onto the pavement of westbound lanes about 20 feet inside California at the state line with Nevada, according to Caltrans.
A Caltrans crew pushed the big rock off the highway into a ditch with heavy equipment. A Caltrans spokesman said the agency would likely return and blast the boulder into smaller pieces, but that action has not been scheduled.
The highway reopened about 1 p.m. Sunday. Nobody was injured, and there were no vehicle crashes.
