After a drenching storm that brought California much-needed rain, a huge section of Highway 1 collapsed near Big Sur, California, on Friday. The washout was triggered when debris flow from the hillside above the highway "overwhelmed drainage infrastructure, flowed across the highway and eroded the road resulting in the complete loss of a segment of Highway 1" at Rat Creek, about 15 miles south of Big Sur, California Department of Transportation (Caltrans) officials said in a statement.
