Heavy rain triggered a landslide or debris flow that destroyed a 30-meter span of a bridge on the A6 motorway between Savona and Turin on November 25. Fortunately, there were no reports of injuries or fatalities. Societa Iniziative Autostradali e Servizi SpA, known as SIAS, manages the roadway where the bridge collapsed and said it was carrying out investigations to assess the situation.
Earlier this month, there was a massive slope failure on the "Sea to Sky" highway in British Columbia. It is interesting to note that this same area had a large rockslide in 1965, and a photo of this failure is featured on the cover of the classic text, Rock Slope Engineering by Hoek and Bray. The media played up the aspect that this highway is one of the only ways to access the site of the 2010 Winter Olympic games hosted by Vancouver.
The composite image above shows the book cover and the recent rockslide event (Photo credit: Erik Eberhardt of the University of British Columbia by way of Dave’s Landslide Blog). Dave has done a fabulous job collecting photos, facts and links from around the web. In a follow up post, he added some additional photos and discussion. I recently came across an article that described how the highway originally was slated to have a tunnel bypassing the slide, but that the price tag of $200 million (CAN?) for a 1-km stretch killed the project.
