SR 87 Landslide Presentation at Roads and Streets Conference

SR 87 landslide in Arizona Last week was the annual American Council of Engineering Companies of Arizona Roads and Streets Conference in my home town of Tucson, Arizona.  Its a transportation themed conference as you might guess, but there are usually a few geotechnical-type presentations. This year, there was an excellent presentation on the SR 87 Landslide that occurred about 1-year ago on the highway between Phoenix and Payson.  The presentation was given by Keith Dhalen, PE with AECOM , Wayne Harrison, RG also with AECOM and Scott Neely, PE with Terracon . Read on for my recap of the presentation. (Photo by ADOT via AZGS)
