Description
The Trans-Alaska Pipeline extends 800 miles (1,287 kilometers) across Alaska, from Prudhoe Bay on the Arctic coast to Valdez on the Southcentral coast. It crosses many obstacles on its way south, including massive mountain ranges, permafrost, and rivers. Here the pipeline crosses the Tanana River near Delta Junction. While the pipeline appears small in this wide angle image, in reality it is four feet in diameter.
Facts about the Pipeline:
Some 420 miles of the 800-mile-long pipeline is elevated on 78,000 vertical support members due to permafrost.
Air temperature along route: minus 80 F to 95 F.
Almost 17 billion barrels have moved through the pipeline.
Controllers can stop pipeline flow within four minutes.
