A section of Highway 1 near Big Sur, California, collapsed on Saturday due to heavy rain from a weekend storm. The collapse occurred around Rocky Creek Bridge, about 17 miles south of Monterey, sending asphalt into the ocean. Caltrans engineers initially closed both directions of the two-lane highway to assess the damage. Around noon on Sunday, the northbound lane was deemed safe, and authorities periodically escorted motorists through. The scenic highway is prone to collapses, mudslides, and rockfalls during heavy rain due to its mountainous terrain.
