Caltrans gave YouTube viewers a front-row seat in this May 2016 video as District 10 maintenance crews clear highways cut through steep and narrow mountain passes. Caltrans maintains three mountain passes: Sonora in Tuolumne County, and Ebbetts and Monitor in Alpine County, Snow and ice must be shoved off the road, rocks and debris must be removed, brush has to be cut back and sometimes 300-ton boulders must be blasted before the highway is safe for public travel. These passes typically close in the fall, and Caltrans begins clearing the passes in April.
