A four-mile stretch of Topanga Canyon Boulevard will remain closed through at least Sunday night after a mudslide triggered by overnight rain inundated a portion of the road Thursday.
The slide, which occurred about 2:30 a.m. on Thursday, forced closure of the roadway between Pacific Coast Highway and Grand View Drive, according to Caltrans. The slide was in the same general area where a mud flow occurred during rains last week.
"After last week's slide, Caltrans installed several hundred feet of K-rail with fence on top for a total height of eight feet to catch mud and rocks," according to Caltrans. "(Thursday's) slide occurred over a gully just outside the parameters of the K-rail in three separate locations within a span of approximately 1,000 feet."
Crews were using skip loaders, backhoes, dump trucks and sweepers in an effort the clear the roadway. A geological engineer from Caltrans was sent to inspect the area.
"With more rain expected, Caltrans will keep the roadway closed through at least Sunday night to clear the roadway, implement any necessary additional slide control, and keep the roadway safe for the public use," Caltrans officials said.
The rural area has no homes or businesses along that section of the roadway, which is one lane in each direction with a shoulder. At least one vehicle got stuck in the mud, but no one was hurt.
This was the third slide on Topanga Canyon Boulevard since a fire in the area in January, Caltrans reported.
