Big Inch




The Big Inch and Little Big Inch, collectively known as the Inch pipelines, are petroleum pipelines extending from Texas to New Jersey, built between 1942 and 1944 as emergency war measures in the U.S. Before World War II, petroleum products were transported from the oil fields of Texas to the north-eastern states by oil tanker. After the United States entered the war on 1 January 1942, this vital link was attacked by German submarines in the Operation Paukenschlag, threatening both the oil supplies to the north-east and its onward transshipment to Great Britain. The Secretary of the Interior, Harold Ickes, championed the pipeline project as a way of transporting petroleum by the more-secure, interior route.
