A bicyclist went around the barricades at the California Highway 1 Devil’s Slide Tunnel project after work hours and rode his bike through one of the tunnels, recording video as he went. I don’t advocate that kind of dangerous behavior, but I must admit that it is neat to see a tunnel nearing completion after several years of work. [Source: YouTube]

Devil’s Slide Repair and Tunnel Bypass Presentation
[Updated Thursday May 29, 2009 – 1:00 PM PDT] Added a photo of the AIS Kaiser S2 excavator (spider excavator), and added photos of the Devil’s Slide debris dump where they have put the landslide material removed and the material from the tunnel excavation. [/Update]
Grant Wilcox, Geology Branch Chief with CALTRANS Office of Geotechnical Design West gave a presentation on the Devil’s Slide repair along PCH Highway 1 at the Southwest Geotechnical Engineer’s Conference on May 12 in Phoenix. I’ve posted about the project here before. When I saw Mr. Wilcox, I knew he looked familiar but I couldn’t figure out why. At the beginning of his presentation he made light of his being on You-Tube…then it clicked! He gave a nice overview of the history of the failures, the geology, and the tunnel project. What follows are a few quick tidbits from his talk based on my notes. (Photo via Caltrans site).
