A huge piece of California's Highway 1 was washed out by a winter storm that brought heavy rain and snow.

California Department of Transportation (Caltrans) officials said in a statement that debris flow from the hillside above the roadway "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, a mountainous stretch of the state's central coast.

At least 25 structures in Northern California have been damaged as a result of mudslides and debris flow caused by a powerful atmospheric river-fueled storm. Most of the impacted areas are where burn scars exist from earlier wildfires.

New drone footage released by the Monterey County Sheriff’s office shows the recent damage wrought on California’s iconic Highway 1, where a portion of the road collapsed after heavy rains washed it into the ocean last week.

The footage shows a large portion of the highway still flooded and covered with debris from recent rainfall and mudslides.

At the point of collapse, about 45 miles south of Carmel in the Big Sur area, both lanes of the road are completely gone, with a massive hole sloping towards towards the Pacific Ocean in its place.

The sheriff’s office footage shows water still running through the collapsed portion of the road, which by Friday had fallen into the sea.
