The landslide hit in May 2017, moving millions of tons of earth and displacing an estimated 75 acres of land.
Traffic starting flowing again through the area Wednesday morning, two days earlier than expected.
"Safe travels, everyone," Caltrans tweeted along with a photo of the new road.

The slide was so big it created 15 acres of new coastline. Caltrans spent about $54 million to rebuild the road.
