Rock's Easy Place

Geotechnical engineers and road planners are being given new options in roadway design. This is due to new technologies, such as improved modeling software, as well as new data analysis methods, many of which haven been developed over the past ten years or so. New possibilities include safely making deeper, steeper rock cuts, and, in some cases, pushing roads through challenging rock masses that may have been previously considered "no-go" areas. Benefits include lower highway grades; higher design speeds through straighter roads and wider curves; less rockfall and landslide risk; less rock transportation during construction; and greater predictability in construction. Inserts provide information on rock-related work on Minnesota's Highway 14 and the use of geological models in supporting Canada's Sea to Sky Highway.
