Running for more than 1,000 kilometers along picturesque coastline, California’s Highway 1 is easy prey for many of the natural hazards plaguing the region, including landslides.

The California Department of Transportation (Caltrans) is currently building a kilometer-long tunnel to bypass one of the most landslide-prone stretches of the highway, the Devil’s Slide, to help ensure drivers’ safe passage.
