Final Spring Pass Clearing Update

Sonora Pass (State Route 108)

Tuolumne County - The California Department of Transportation (Caltrans) will formally reopen Sonora Pass on State Route 108 on Thursday, April 30, 2026, at 10:00 a.m.

Our District 10 Long Barn Maintenance crew made great progress clearing Sonora Pass this season exceeding our annual goal of reopening State Route 108 prior to Memorial Day.

Sonora Pass, at 9,624 feet of elevation, is the second highest point on the state highway system maintained by Caltrans. The highway was formally closed for the winter season on December 26, 2025, at the Sno-Park on State Route 108 just north of Strawberry. Our District 10 Long Barn crew began their snow removal operations in late March at the Sno-Park, approximately 28 miles to the summit, and worked diligently to clear the pass of snow, ice, down trees and debris.

Caltrans top priority is ensuring the safety of the traveling public and our workers along with supporting the economic vitality of our local communities. We are pleased to reopen State Route 108 for the season without incident and to allow early public access for recreation activities along Sonora Pass.
