MARIPOSA COUNTY – The California Department of Transportation (Caltrans) has completed the process of dislodging overhanging rocks at the site of the Ferguson rock slide and will begin removing more than 100,000 tons of rocks this month as it continues the Ferguson Rock Shed project on State Route 140 in the Merced River Canyon.
Approximately 20 trucks, each with 20 tons of capacity, will remove as many as 80 total loads from the site per day. The work is scheduled to occur during daytime hours Monday through Friday beginning this month until November 2021.
More than 140,000 tons of rocks (talus) will be cleared, making way for workers to construct a 675-foot long shed that will protect motorists from future slides and restore full access for the community of El Portal and visitors to Yosemite National Park on Route 140 in Mariposa County.
Travelers can access El Portal and Yosemite National Park on Route 140 via the existing temporary vehicle bridges over the Merced River or take Route 120 into the park.
Construction of the shed is scheduled to begin in spring 2022 and is anticipated to
continue through 2027.
This work is subject to change due to traffic incidents, weather, availability of equipment, and/or materials and construction related issues.
Caltrans reminds motorists to Be Work Zone Alert.
