Caltrans is closing Ebbetts Pass on Highway 4, Monitor Pass on Highway 89 and Sonora Pass on Highway 108 in advance of the Thanksgiving holiday weekend due to a strong winter storm forecast for the Sierra.

Planned closures are as follows (subject to change depending on conditions):

uEbbetts Pass at noon today

uSonora Pass at 1 noon today

uMonitor Pass at 1 p.m. today

No decision has been made at this time regarding the seasonal closure of these routes. Caltrans will assess the routes after the Thanksgiving holiday weekend to determine the seasonal closure status.

Tioga Pass, a continuation of Highway 120 within Yosemite National Park, remains closed at this time. Yosemite crews maintain all roads within the park. 

Several factors influence the temporary closing and opening and seasonal closures of mountain pass roadways. Storms, accumulation of snow and overall road conditions are all considered in the decision-making process by Caltrans leadership. For the safety of motorists and Caltrans crews, these passes will be continually assessed until the seasonal closure of each is decided.
