 to build a deep-water shipping canal between the river and lake. Considerable land was expropriated in the downriver portion of the city. Toward the lake this was mostly little-developed swamp. Along the riverfront, though, buildings demolished to make room for the canal included homes and the Ursuline Convent, whose Dauphine Street facility was nearly a century old at that time.

Dredging of the canal began on 6 June 1918. The length from the lake to the lock near the river was constructed with a 30 foot (9 m) depth, with a width of 300 feet (90 m) at the top of the canal and at least 150 feet (45 m) at the bottom. The original lock system had 5 gates, a width of 74 feet (23 m), and a depth of 50 feet (15 m), with a capability to function to up to 20 feet (6 m) in difference of levels between the river and lake. The opening dedication ceremony was presided over by Louisiana Governor John M. Parker

The original length of the canal was 5.3 miles (8.5 km) with a 1,600 foot (500 m) right-of way. The longer current length of 5.5 miles (8.9 km) is due to the extension of the lakeshore by dredging in the late 1920s.

After the opening of the canal, slips and docks were added along its length, allowing it to function as a harbor

 with larger modern locks sited to the north of Claiborne Avenue.

Maritime interests argue that in light of the closure of the MRGO, and the loss of the deepwater access it provided to the Gulf of Mexico, modern oceangoing vessels are unable to access the inner harbor of the Industrial Canal, permanently limiting the canal's utility as a site for shipyards and other industry requiring water access. Without a new lock, the port's France Road Container Terminal and Jourdan Road Wharf would also remain closed due to the inadequate deepwater access. Proponents of the new lock additionally cite dwindling barge traffic as evidence that the existing obsolete lock is choking off commerce. Opponents point to the same figures to support their contention that insufficient demand exists to justify the new lock.
