Transport in Antarctica

Transport in Antarctica has transformed from explorers crossing the isolated remote area of Antarctica by foot to a more open area due to human technologies enabling more convenient and faster transport, predominantly by air and water, as well as land. Transportation technologies on a remote area like Antarctica need to be able to deal with extremely low temperatures and continuous winds to ensure the travelers' safety. Due to the fragility of the Antarctic environment, only a limited amount of transport movements can take place and sustainable transportation technologies have to be used to reduce the ecological footprint. The infrastructure of land, water and air transport needs to be safe and sustainable. Currently thousands of tourists and hundreds of scientists a year rely on the Antarctic transportation system.

Winds continuously blow snow on roads in Antarctica.

The South Pole Traverse (McMurdo–South Pole highway) is approximately 1,450 km (900 mi) long and links the United States' 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. There are flags to mark the route.

Also, the United States Antarctic Program maintains two ice roads during the austral summer. One provides access to Pegasus Field on the Ross Ice Shelf. The ice road between Pegasus Field and McMurdo Station is about 14 miles. The other road provides access to the Ice Runway, which is on sea ice. The road between the Ice Runway and McMurdo Station varies in length from year to year depending on many factors, including ice stability. These roads are critical for resuppling McMurdo Station, Scott Base, and Amundsen–Scott South Pole Station.
