South Pole Traverse
The South Pole Traverse, also called the McMurdo–South Pole Highway, is an approximately compacted snow road in Antarctica that links the United States's McMurdo Station on the coast to the Amundsen–Scott South Pole Station. It was constructed by leveling snow and filling in crevasses, but is not paved; flags mark its route.
==Route description==
After four years of development, the trail is now operational, with Caterpillar and Case Corp. tractors pulling specialized sleds to deliver fuel and cargo to the South Pole in about 40 days. The return trip to McMurdo Station, with less fuel and cargo, is substantially quicker. Construction started during the 2002/03 southern summer field season. It was finished in the 2005/2006 southern summer.
The McMurdo Ice Shelf and the Antarctic Plateau are relatively stable. Most crevasses occur in the short steep shear zone between them, where the road climbs to more than above sea level. This section of the road needs maintenance each season. The section caused much more construction work than planned, because the ice sheets are likely to move.
