Super Sky Tram
For over 40 years the Big Red Box at Jackson Hole, Wyoming, carried skiers, hikers, paragliders and sightseers up to the 3,400-metre summit of Rendezvous Mountain. But nothing lasts forever, so when cable inspector Norm Duke found evidence of stress fractures inside the aging steel track cables, there was no choice but to tear down and replace Jackson's iconic aerial tram. At a cost of US$31 million, this two year construction project is a top-to-bottom, state-of-the-art replacement. It will operate in 120 kph winds and minus 30°C temperatures, all with the quiet precision of a giant Swiss watch. Construction crews battle a record-breaking snowfall, zero visibility, high winds and impassable mud-slick mountain roads to build its five towers and two terminals, and string more than ten miles of heavy steel cable as they risk their lives in a battle to finish before winter closes in.
