A giant rock “the size of a building” is blocking a highway in Colorado, officials said. A rock slide Friday afternoon resulted in two boulders that destroyed a large portion of the pavement, closing the road “indefinitely.”

CDOT crews used explosives to break apart a house-sized 2.5 million-pound boulder that came off the hillside and landed on the highway.
