DESIGN OPTIONS FOR ROAD WIDENING IN MOUNTAINOUS TERRAIN

Many roads in the mountainous terrain on British Columbia are located in valleys on steep slopes with rockfall hazard potential, beside environmentally sensitive areas. Because of ever increasing traffic volumes and the need for improved highway safety, many highways in British Columbia require widening in areas constrained heavily by topography, geology and the environment. This paper presents four design options for widening highways in such areas, two of which are highlighted in case histories.

• Supplemental Notes:
  • Unlike most groups and organizations that meet on a regular basis, the Highway Geology Symposium has no central headquarters, no annual fees, and no formal membership requirements. The governing body of the Symposium is a Steering Committee. Recent proceedings may be obtained from the Treasurer of the Symposium, Mr. Russell Glass.
