Women's Downhill Tunnel

located in Whistler Mountain, Highway 86/Franz's Run

CME performed the major cuts and fills and ski run grading of the 2010 Women's Downhill race course from summer 2007 – summer 2009. From the famed "Frog Bank" turn, that challenged the best female skiers in the world, to the exciting "Tunnel Jump" CME build it all. The largest component of this project was the design and build of North America's largest multi-plate corrugated steel tunnel that allowed public ski traffic on Whistler Mountain to cross the Olympic Downhill run with no interruption. Whether you're skiing through the tunnel in the winter, or biking through in the summer, you can see CME left their stamp on Whistler Mountain and a legacy to the 2010 Games.
