Mountain Passes Closed for the Season

CALTRANS CLOSING MOUNTAIN PASSES FOR WINTER SEASON
MONITOR PASS/STATE ROUTE 89, EBBETTS PASS/STATE ROUTE 4 & SONORA
PASS/STATE ROUTE 108 CLOSED UNTIL SPRING DUE TO EXCESSIVE SNOW
STOCKTON – Following this weekend’s storm that dropped snow throughout the Sierra Nevada, and with more inclement weather forecast this week, Caltrans will close Monitor Pass/State Route 89, Ebbetts Pass/SR-4 and Sonora Pass/SR-108 today (December 15, 2020) at 12 noon for the winter season. These three passes had already been closed on a temporary basis due to snow, ice and weather.

Tioga Pass, a continuation of SR-120 within Yosemite National Park, has already been closed for winter. Yosemite crews maintain all roads within the park.

Several factors influence the temporary closing, opening, and seasonal closures of our mountain pass roadways. Storms, accumulation of snow and overall road conditions are all considered in the decision-making process.

The mountain passes will be closed at these locations:
• Monitor Pass/SR-89 will be closed from the State Route 4 Junction in Alpine
County to the Interstate 395 Junction in Mono County;
• Ebbetts Pass/SR-4 will be closed from the west end of Lake Alpine in Alpine
County to the SR-89 junction in Alpine County;
• Sonora Pass/SR-108 will be closed from the SnoPark east of Strawberry in
Tuolumne County to six miles west of I-395 in Mono County.

These mountain passes will remain closed until the winter storm season has passed. Prior to opening in 2021, these highways will be cleared of snow and debris, then District 10 maintenance will inspect the roadways and make necessary repairs before they are opened to the traveling public.
