A landslide with “basketball-sized and smaller” rocks has closed both lanes of U.S. 199 just south of Patrick’s Creek, according to the California Highway Patrol.

As of about 4:40 p.m. Wednesday, there was no official report of when the road would reopen, said Caltrans spokesman Myles Cochrane. He said crews were still working on clearing the slide and getting traffic moving.

The CHP received a call for rocks in the roadway at about 1:10 p.m., Officer Brandon Banks said Wednesday. As of 3:25 p.m. the highway was completely blocked off at mile marker 15 on the south side of the slide and at mile marker 22 at the north end, he said.

According to a Facebook post from the Gasquet Volunteer Fire Department, the landslide occurred near the Sandy Beach river access.

“Caltrans is on scene and they’re definitely aware of it and actively working on it,” Banks said.

It’s unclear at this time when the road will reopen, Banks said. There was no information that any vehicles were involved in the slide, he said.

Cochrane said Caltrans would post updated information to its District 1 Facebook page, https://www.facebook.com/CaltransD1/.
