Viaduc de Martigues

The Viaduc de Martigues is a road bridge spanning the Canal de Caronte with two traffic lanes carrying vehicles above the waterway. The structure stretches approximately 875 meters and features a distinctive central metal section.

The bridge was completed in 1972 using innovative construction methods with prefabricated metal components. These modern techniques made it possible to build a long span crossing the waterway.

The Viaduc de Martigues represents a milestone in French infrastructure development, connecting the regions while maintaining maritime navigation through the canal below.

The bridge connects the two sides and enables direct travel between Marseille and Fos-sur-Mer. Pedestrians and cyclists can use the road, but should expect heavy traffic at most times.

The bridge was built using parts transported by ship and rail, which was unusual for the time. This logistics system made it possible to complete the structure without heavily disrupting the area.
