Big Inch Pipeline

Big Inch Pipeline. . , Before the United States entry into World War II following the bombing of Pearl Harbor in December 1941, ninety-five percent of the crude oil delivered to East Coast refineries was transported by tanker ships. Ninety percent of that oil originated from Texas oil fields. , , Beginning in February 1942, many U.S. oil tankers en route from the Gulf of Mexico to the East Coast were sunk by German submarines. Recognizing the need to transport oil under safer circumstances, Secretary of the Interior Harold Ickes developed a plan for massive overland oil pipeline. Under the auspices of the War Emergency Pipelines, Inc., construction began on the largest pipeline in history up to that time. Measuring twenty-four inches in diameter, the Big Inch pipeline extended from Longview to Norris City, Illinois, and eventually to refineries in the East. , The Big Inch pipeline's impact on the war effort was tremendous, enabling the safe and timely transport of oil products vital to the Allies. During the height of wartime service, over 300,000 barrels of oil were delivered each day over the 1,476-mile line. When the war ended the Big Inch continued in service after conversion to a natural gas pipeline.
