Deerfoot Trail Extension – Innovative Approach Leads to Geometric Innovations

The Deerfoot Trail Extension is 11 km of new freeway, which was completed in 2004. The project cost $100M, and extends south from Hwy 22X to the existing Hwy 2 /2A interchange south of Calgary. This completes a previously missing direct link in Hwy 2, which is part of the North / South trade corridor through Alberta. In addition to completing the “missing link” in the north/south trade corridor through Alberta, the Deerfoot Trail Extension has made life easier for many Calgary commuters, who say that it has taken some 20 minutes off their drive to work each day. It has also been of benefit to the motor transport industry as it eliminates stop and go traffic, and is a much more direct route. Since it opened, collision rates have been very low, and driver reports have been very positive and complementary. Drivers have adapted very well to the two lane loop ramp and major fork, and environmental agencies are very satisfied that this project has met its goal to “mitigate impacts through good design and construction practices.” Drivers are particularly appreciative of the fact that the project was built with all interchange structures in place on opening day, so that no traffic lights were required to stop through traffic. All of the above Geometric and environmental innovations are the direct result of the innovative approach developed by the project team at the beginning of the project.
