MegaStructures - Season 6 - Eps 13: 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.

Synopsis
MegaStructures is a documentary television series appearing on the National Geographic Channel in the United States and the United Kingdom, Channel 5 in the United Kingdom, France 5 in France, and 7mate in Australia. Each episode is an educational look of varying depth into the construction, operation, and staffing of various structures or construction projects, but not ordinary construction products. Generally containing interviews with designers and project managers, it presents the problems of construction and the methodology or techniques used to overcome obstacles. In some cases this involved the development of new materials or products that are now in general use within the construction industry. MegaStructures focuses on constructions that are extreme; in the sense that they are the biggest, tallest, longest, or deepest in the world. Alternatively, a project may appear if it had an element of novelty or are a world first. This type of project is known as a Megaproject.
