Caltrans reopened all lanes of PCH around 8 p.m.
A stormy system had moved into the Southland Saturday night and sudden downpours triggered debris flows that shuttered 13 miles of the road between Malibu and Oxnard.
Crews had worked day and night to clear out the muck, which had caused several vehicles to get stuck.
Luckily, no one was injured when the mudslides and flooding occurred.
Caltrans officials said Decker Canyon Road remained closed indefinitely.
