Highway 101 in northern Mendocino County will be closed until at least Wednesday following a Sunday night landslide that dumped more than 6,000 cubic yards of rocks and soil onto the road, Caltrans has reported.
The affected two-lane section of highway, about six miles north of Leggett, already was undergoing repairs and limited to one lane of traffic before the slide occurred, said Caltrans Spokesman Phil Frisbie. Traffic has been limited since the road was closed March 10 following a previous landslide.
The area has been subject to rock slides in the past, but had been relatively stable for a number of years, Frisbie said.
Caltrans advises people heading north to Humboldt County and beyond to use Highway 5 until the road is cleared.
