Restoring California Wagon Trail May Cost Billions and Harm Redwoods

The California Department of Transportation plans to build a 6,000-foot tunnel to bypass the unstable "Last Chance Grade" section of US Highway 101 in Del Norte County, at an estimated cost of $2.5 billion. The project aims to address decades of land movement and landslides that have made the highway intermittently closed or restricted, posing dangers and detours for residents and travelers. Construction could begin around 2031, with the tunnel opening projected by 2039, despite environmental concerns including the removal of old-growth redwood trees.
