Lasers, Software and the Devil’s Slide

[Editor] National Science Foundation (NSF) Press Release – June 30, 2008. Screenshot Credits: Jeramy Decker, Kiewit Corp [/Editor]

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.

Using a new software package developed by researchers at Virginia Tech in Blacksburg, Va., project engineers are getting a detailed 3-D view of the rock exposed in the excavation, adding a new tool for improving both safety and construction progress.

Devil’s Slide Tunnel, Project Updates and Geotechnical Info

Devil’s Slide is an infamous landslide along California’s Highway 1 or Pacific Coast Highway near Pacifica, just south of the San Francisco Bay area. Caltrans’ Devil’s Slide Tunnel project is an effort to bypass that slide and make the heavily traveled roadway safe for drivers and to eliminate the maintenance and traffic hassles caused by slope failures blocking the road. We first covered the project back in September of 2007 when the tunnel portion of the project commenced. In that post, you can find a Google Earth KML File showing the location of the tunnels and the new bridges associated with the project. In this post, I’ll provide you with some updated progress information as well as some background on the geotechnical and other aspects of the project. More links and videos are at the end of the post.  (Photo by Kim Komenich, San Francisco Chronicle). […]
