Highway 101 Fully Closed in Northern Mendocino due to Snow Conditions; Chain Controls on 299 and 36


Photo submitted by Amy Norton, who said she made it through this stretch just before it was closed: “Being advised not to continue without four wheel drive and proper tires. Cars lined up to turn around or being turned back. Semis off side of road.”

UPDATE, 1/27: As of Wednesday morning, Highway 101 is still closed north of Laytonville due to snow. Hang in there.

Original Post: It’s getting pretty wild on the roads out there! Caltrans reports that the stretch of Highway 101 between Cummings and Laytonville is currently closed to traffic as crews work to clear snow from the roadway there. More updates on that incident can be found below. LoCO will update when we know more.

Elsewhere, there are chain controls in effect on Highway 299 starting at Berry Summit and on Highway 36 starting just west of Dinsmore.

More storm day roads mayhem as it develops on LoCO’s CHP Watch.
