Caltrans has lifted chain restrictions on Highway 175 at the Hopland Grade near the Lake-Mendocino county line, as well as atop Cobb Mountain, the agency said.

Early morning snow had prompted requirements for chains or snow tires on the two lengths of highway, as well as several other locations principally around Lake County.

All chain restrictions have now been lifted in Lake and Mendocino counties, and all highways are open, the CHP said.
