A section of Coast Highway (map) was temporarily closed in both directions Friday morning in Dana Point after a large boulder tumbled onto the roadway, authorities said.
Deputies responded at 3:55 a.m. after receiving reports of a 10-feet-by-20-feet boulder on the highway, said Lt. Andy Ferguson of the Orange County Sheriff’s Department.
The deputies discovered the large boulder as well as several smaller ones in multiple lanes.
Lanes had reopened in both directions by about 10:45 a.m., according to a Caltrans District 12 tweet.
Authorities had initially said the rockslide occurred on Pacific Coast Highway, which terminates about one mile north of the scene.
Coast Highway had been closed between Camino Capistrano and Beach Road until the obstructions were removed, the Sheriff’s Department said. Detours had been posted at the scene.
