Session: M1-A

ABSTRACT: Alberta Transportation has completed geohazard reviews of the Highway 40/541, 742 and 940 corridors in the Front Ranges and Foothills of southwestern Alberta. The purpose of this work was to gather information on the geohazards present along the corridors and the associated risks to the highways that have not been assessed to date under Alberta Transportation's Geohazard Risk Management Program for the provincial highway network. The information from the reviews has been used to estimate the Risk Level for these sites and prioritize them amongst other geohazard sites currently being monitored by Alberta Transportation. This paper discusses the geohazard conditions along these highway corridors, the methodology for the reviews and summarizes the results and their application.

RÉSUMÉ: Alberta Transportation a complété une revue des géorisques aux abords des routes 40/541, 742 et 940 dans la région des Front Ranges et Foothills, dans le sud-ouest de l'Alberta. Le but de ces travaux était de receuillir de l'information sur les géorisques existants le long de ces corridors, de même que sur les risques associés pour ces routes qui n'avaient pas encore été évaluées par Alberta Transportation dans le cadre de son programme de gestion des géorisques du réseau routier provincial. Les informations receuillies ont été utilisées pour estimer le niveau de risque et prioriser ces sites parmi d'autres faisant actuellement l'objet d'un suivi par Alberta Transportation. Cet article présente les géorisques relevés le long de ces corridors routiers, la méthodologie utilisée pour leur identification, les résultats et leur application.
