The Big Inch and its companion project, the Little Big Inch, are petroleum pipelines constructed during 1942 and 1943 as an emergency war measure from Texas to New Jersey. Until World War II, petroleum products had been transported from the oil fields of Texas to the northeastern United States by oil tanker. With the entry of the United States into the war, this vital link was attacked by U-boats, threatening both the supplies to the eastern United States and onward transshipment to Great Britain. The Inch pipelines were conceived as a way to transport increased quantities of petroleum by a secure, interior route, with the additional benefit of freeing tankers for other tasks. At the time of their construction, they were the longest petroleum pipelines ever built. The pipelines remain in use.
