Project Description

Jackson Hole Mountain Resort announced the retirement of their historic, 40-year-old aerial tram at the end of the 2006 summer season. The tram was an iconic feature, recognized around the world as a lift that accessed some of the most spectacular terrain in North America.  A new 100-person aerial tramway was constructed to replace the existing lift, following the same alignment. The new tram, completed in December of 2008, has a vertical lift of 4,139 feet and the longest continual vertical rise of any ski lift in North America.

Crux’s Role

The new aerial tramway consists of a lower terminal, five tower foundations, and an upper terminal. The five tower foundations utilize micropile/rock anchors with a concrete cap at each of the tower legs. The upper and lower terminals consist of large footings and highly reinforced foundations to support the cable bollards. Tower locations are positioned in limited access locations with some being situated directly above 300-foot cliffs.

Crux engineered and built a hoisting system that integrated with the existing tram cars and was used to transport equipment, materials and crews to new foundation locations. Crux utilized existing dirt roads to gain access to the upper terminal locations and areas near the tower foundations. The old tram was also used to transport ready-mixed concrete from the mountain base to tower locations. In conjunction with the tram, Crux utilized a remote batch plant at the upper terminal location for concrete placement.

During construction, micropile design was modified to accommodate constructability of foundations, foundation loading, and geotechnical conditions. Crux played a key role in the engineering of several tower foundations. The removal of the existing tram was scheduled for fall of 2007 with the installation of the new Doppelmayr/CTEC beginning in spring 2008.
