browse=McMurdo-South Pole highway is a 900-mile (1450 km) road in
Antarctica to link theUnited States McMurdo Station on the coast to theAmundsen-Scott South Pole Station . It was constructed by leveling snow and filling increvasse s, but not paved. Todaycaterpillar tractor s are able to drive to theSouth Pole , which will take 10 days.The construction started in late 2002. It was finished in the southern summer of 2006-2007.
The
McMurdo Ice Shelf and theAntarctic Plateau are relatively stable. Most crevasses occur in the short, steep shear zone where the road would climb to over 2000 meters above sea level; this section of the road would need maintenance each season. The section has caused much more construction work than planned, since two different ice sheets move against each other here.The project was funded by the United States
National Science Foundation to provide a lower cost, potentially more reliable method of supplying the South Pole Station. Bad weather at McMurdo some summers has reduced the total number of supply flights the NSF could make to bring in construction supplies and scientific equipment.The road also facilitated the heavy equipment needed to implement its proposed South Pole Connectivity Program, a planned
optical fiber link between the South Pole and the French-ItalianConcordia Station located atDome C at the edge of the Antarctic Plateau; Concordia has 24-hour access to geosynchronous satellites. Such satellites cannot be used at the poles since they are below the horizon; the South Pole now uses a few older, low-bandwidth satellites that dip sufficiently south of the equator to be usable for several hours daily. These satellites are near the end of their life. A new road to McMurdo might provide a regularly maintained alternate route for such a link; however, opinions vary as to the shear zone section's suitability for a long-term cable. It's also possible the NSF may choose to deploy several special purpose satellites in polar orbits.
