Caltrans Clears 20-Ton Boulder from U.S. Highway 50 With Controlled Detonation

Massive Rock Slid into Roadway, Posing Safety Hazard on Rugged, Rural Road

SACRAMENTO – What do you do when a 20-ton boulder slides down the hill and blocks a rugged rural road in winter weather? In Caltrans’ case, you secure the area, dispatch trained crews and blow it up. Then you clean up the debris and get motorists moving again. This Caltrans News Flash explores the process from beginning to end.

It’s all in a day’s work for Caltrans crews, who cleared this behemoth on U.S. Highway 50 about 80 miles east of Sacramento.
