High Tension Median Cable Barriers

摘要

Between 1999 and 2005 there were seven fatal crossover collisions on an 11-kilometre segment of the Deerfoot Trail in Calgary. The six-lane divided urban freeway between 16th Avenue NE and Country Hills Boulevard carries up to 150,000 vehicles a day. Since a high-tension median cable barrier was installed in May 2007, however, there have been no crossover collisions on that section of roadway at all. This relatively new type of median barrier has proved so successful at preventing crossover collisions that Alberta Transportation has also installed it on 127 kilometres of Highway 2 between Calgary and Leduc, Alberta. EBA Engineering Consultants designed the median barrier for both projects.
