The Pass Remains Closed – November 21, 2017

November 21, 2017 – Cal Trans has informed us that the pass is still closed but may open again.  They will make an asessment next week. Several factors weigh in to influence the temporary closing, seasonal closures and opening of our pass roadways.  Storms, accumulation of snow, and road conditions are all considered in the decision-making process. For the safety of motorists and Caltrans crews, continual updating of these passes will be assessed until the seasonal closure of each is decided. SR 108, Sonora Pass, is now closed for the season.

November 20, 2017 – Quick Update – The pass is still closed and we are hoping for additional snow accumulation over the next day or two. It is possible that the pass may re-open briefly if the weather is warm for any length of time but, the season closure can’t be far off.  Always check conditions before planning a trip over the mountains and be prepared for unexpected changes in the weather.

STOCKTON – The California Department of Transportation (Caltrans) is scheduled to close State Routes 4, 108 and 120 in the Sierra Nevada today, Thursday, November 2, due to incoming inclement weather. The closures are planned as follows (subject to change depending on actual conditions):
