Rockslide closes both lanes of Highway 101 near Piercy


PIERCY, Calif. - Due to a rock and mudslide, U.S. Highway 101 is closed near Piercy and traffic is being rerouted.

At around 10 a.m. Thursday, Caltrans announced that a well-known rock and mudslide area along U.S. 101 has caused a highway closure near Piercy.

Caltrans said traffic is being detoured onto Route 271, and drivers should anticipate five to 10 minutes of extra travel time. The agency also said the closure and detour will remain in place until sometime on Friday. "The closure is due to last winter's slide beginning to act up again," Cal Trans District 1 said via Facebook.

According to Cori Reed, a spokesperson with Caltrans, the problematic slide area has been referred to by Caltrans as the "Piercy Slide."

Rather than wait until the slide begins to close the northbound lanes, Caltrans said it is proactively closing the northbound lanes, as was done last winter during problems caused by the area, by installing concrete k-rail, semi-permanent delineators (orange plastic posts) and temporary striping that will safely allow one lane of both north and southbound traffic to use the southbound lanes. This reduction to one lane in each direction will likely remain in place through the winter.

Reed said two-way traffic should be able to pass through the area on Friday.
