How did the Canal du Midi improve transportation and commerce in France?

The Canal du Midi was constructed during the reign of Louis XIV to serve as a strategic shortcut between the Atlantic Ocean and the Mediterranean Sea, aiming to bypass the long and hazardous sea route around the Iberian Peninsula.12

While the canal was a landmark achievement in civil engineering, its impact on commerce was limited. Although it was reasonably successful financially, it remained largely isolated from the rest of the French canal system until the 19th century. Furthermore, because the canal's locks were built to smaller dimensions than the later standard French requirements, it could not accommodate large-scale shipping. Consequently, the canal never carried a significant volume of goods to destinations outside its immediate region, and it did not fulfill the original vision of becoming a major artery for international maritime trade. Today, the canal is primarily recognized for its historical significance as a UNESCO World Heritage site and its popularity for leisure boating.2
