When the roads are open. Highway 4 closes for the winter just east of highway 207. Highway 89 is closed from the junction with highway 4 over Monitor Pass down to US395. Generally, CalTrans closes these highways around Thanksgiving, and reopens them any time between April 15 and June 30, depending upon snowfall and any road damage occurring during the winter from avalanches and boulders.Copperopolis, CA
