A huge 35,000 to 40,000 cubic yard landslide has blocked Highway 26/89 for about 300 feet with material about 40 feet high. The slide is about 2000 feet long, terminating in the Snake River. It is still moving about 1 foot per day. Plans are in place to begin clearing the material, but WYDOT does not want to start until the risk of more material coming down has subsided.

Comments Off on Geotechnical Engineering Challenges of British Columbia’s Sea-to-Sky Highway, gateway to the 2010 Vancouver Olympic Games
I don’t know about you, but I’ve been enjoying watching the 2010 Olympic Winter games over the past few days. If you have, you know that Whistler is the venue for many of the sports including alpine skiing, luge, skeleton, bobsled, ski jumping, biathlon and cross-country skiing among others. The Whistler area is located about 50-miles or so North of Vancouver. In order to get to Whistler, you need to drive along Highway 99, better known as the Sea-to-Sky Highway. This highway has a long history of geotechnical problems, including some significant structurally controlled rockslides and landslides. In the years leading up to these Olympic Games a fair amount of work was done on the highway with some significant geotechnical innovations.
