A large section of road that has been closed since September collapsed into the ocean Sunday in San Pedro.
The landslide, which began during the summer, washed part of the cliff into the ocean Sunday afternoon. The collapse means it's likely a new route for the scenic roadway will have to be considered.
No injuries were reported and no structures were threatened.
City engineers are attempting to determine what caused the initial landslide near the White Point Nature Preserve. Signs were posted, warning residents to stay away from the unstable area.
Some of the original road closed signs were swept away in Sunday's collapse.
"It is devastating," said Rep. Janice Hahn. "I'm worried about these homes. They're the front row on the ocean."
The landslide was moving at a rate of 4 inches per day, according to city engineers. Officials with the public works department told NBC4 that it could be six months before there's a solution.
"My greatest concern is that all these homes are going to end up in the water, and that we're going to be separated like our own little island," a resident told NBC4.
Sunday's slide caused powerlines to sway along the nearly 900-foot section of road between South Western and South Weymouth avenues.
