How will CA_140 be rockslide reduced?
The numbers on the Ferguson Rock Slide are fairly staggering (per the article and video):
- 226,000,000 pounds of rock covered about 750 feet of the highway in 2006
- 70,000 cubic yards of rock to remove
- 885 feet from top of slide to the Merced River
This project will result in the removal of the temporary, one-lane bridge that serves as the temporary route of SR 140 and also result in the installation of a rock shed to protect the highway.
