Canal de Givors, Historical canal in Givors and Rive-de-Gier, France.
The Canal de Givors is a waterway about 15.5 kilometers long connecting several communes in the Loire department with 29 locks for water management. Today the structure runs partly beneath the A47 motorway, but remains visible at various points along its original path.
Construction began in 1763 under the direction of François Zacharie and opened in 1780 as an alternative route for goods transportation. It enabled the movement of coal and glass through the valley, shaping the region's economic development for decades.
The waterway transformed how people in surrounding towns thought about commerce and connection, making distant trade suddenly practical. Its path through the landscape still marks the memory of communities that once depended on its flow for their livelihoods.
The structure is visible at several locations, but much of it now lies beneath the modern motorway, so plan visits to accessible sections. Walking along the exposed segments in the surrounding communes offers the best way to understand what remains of this historic route.
The waterway carried around 140,000 tons of goods annually at its peak before railways started replacing it in the 1830s. This sudden shift in transportation technology shows how quickly new inventions could make older infrastructure less useful.
