March 27, 1975Construction of the Trans-Alaska Pipeline System begins.
The Trans Alaska Pipeline System (TAPS), includes the Trans Alaska Pipeline, 11 pump stations, several hundred miles of feeder pipelines, and the Valdez Marine Terminal. TAPS is one of the world's largest pipeline systems. It is commonly called the Alaska Pipeline, Trans Alaska Pipeline, or Alyeska Pipeline, (or the Pipeline as referred to in Alaska), but those terms technically apply only to the 800 miles (1,287 km) of the pipeline with the diameter of 48 inches (122 cm) that conveys oil from Prudhoe Bay, to Valdez, Alaska. The crude oil pipeline is privately owned by the Alyeska Pipeline Service Company.
