History
The Industrial Canal and Lock were built by the Port of New Orleans to provide navigation between the Mississippi River and Lake Pontchartrain. The project was completed in 1923.
In the 1930s, the federal Gulf Intracoastal Waterway connected to the Industrial Canal via Lake Pontchartrain and used the lock to connect to the Mississippi River. Commercial traffic using the lock paid a local toll of 5 cents per gross ton. Beginning in 1944, the federal government leased the lock and the southern segment of the canal, eliminating the toll.
In 1965 another waterway, the Mississippi River-Gulf Outlet Canal (MRGO), was completed and began using Industrial Lock. The MRGO was a deep-draft channel affording ocean-going vessels a short-cut from the Port of New Orleans to the Gulf of Mexico. Thus three different waterways—the Industrial Canal, the Intracoastal and the MRGO—were now using the same lock to connect to the river.
In 1986 the federal government purchased the Industrial Lock from the Port of New Orleans.

Famous quotes containing the word history:
“Properly speaking, history is nothing but the crimes and misfortunes of the human race.”
—Pierre Bayle (1647–1706)
“When the coherence of the parts of a stone, or even that composition of parts which renders it extended; when these familiar objects, I say, are so inexplicable, and contain circumstances so repugnant and contradictory; with what assurance can we decide concerning the origin of worlds, or trace their history from eternity to eternity?”
—David Hume (1711–1776)
“Books of natural history aim commonly to be hasty schedules, or inventories of God’s property, by some clerk. They do not in the least teach the divine view of nature, but the popular view, or rather the popular method of studying nature, and make haste to conduct the persevering pupil only into that dilemma where the professors always dwell.”
—Henry David Thoreau (1817–1862)
