The slope, the second and last to be constructed in France, was built between 1980 and 1983 with the intent of replacing the seven locks at the
Fonseranes Locks. Trial operations commenced in May 1984. However, within weeks a number of technical problems emerged as oil leaking from the hydraulic system lubricated the concrete tracks and the wheels on the lift were unable to gain sufficient traction to raise the chamber to the top of the slope. It took until 1986 to resolve the technical, contractual, and insurance issues.
This problem was never satisfactorily resolved and the slope was abandoned officially on 11 April 2001.
