SR 140 - Ferguson Project


DESCRIPTION

The California Department of Transportation (Caltrans), as assigned by the Federal Highway Administration proposes to permanently restore the section of SR-140 that was damaged by the Ferguson rockslide. Permanently restore full highway access on State Route 140 between the communities of El Portal and Mariposa by removing loose debris (talus) caused by the 2006 Ferguson Rockslide. Crews will also construct a 2-lane structure on the original alignment. The $133 million project has been split into two phases. Phase 1 will remove the existing talus material and install cable net drapery to minimize additional rock fall. Phase 2 will construct a 750-foot structure on the same alignment.


PROJECT BENEFITS

The purpose of the project is to reopen and permanently restore full access to the section of State Route 140 (SR-140), which was damaged by the Ferguson rockslide. Currently, motorists use a temporary bypass route to travel this portion of SR-140. Restoration of SR-140 would eliminate inconvenient detours or extended commute times for residents, businesses, and workers in the area. Restoration of the route would also give travelers a direct route to Yosemite National Park and other destinations along SR-140.

PROJECT SCHEDULE

Phase 1: Talus Removal

  • Contractor: Myers & Sons/ R.L. Wadsworth
  • Anticipated Construction: March 2015 to June 2017
  • Additional geotechnical bores will be taken once talus material is removed.
  • Project site will be inactive until the rockshed design is completed and contracting process for Phase 2 is completed.

Construction of the rock shed was originally anticipated to begin in March 2016, if weather permitted; however, during the winter suspension of the project there was rock fall and a significant rockslide in November 2015. The Caltrans Office of Geotechnical Services assessed area and the project team decided more assessment was needed to determine the stability of the slope.
