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. This paper will provide an overview of the project, the process that led to innovation, and the two major geometric innovations, the "two lane loop ramp", and the "major fork".
