Littoral Viaduct, Road bridge in Saint-Denis, France.
The Littoral Viaduct extends 5.4 kilometers across the Indian Ocean, rising 30 meters above sea level along the coast of Réunion Island.
Construction of this concrete infrastructure began in March 2019 to replace the existing coastal road affected by cliff erosion and weather conditions.
The viaduct forms part of the Nouvelle Route du Littoral, connecting Saint-Denis to La Possession while integrating with the island's transportation system.
The structure contains 48 marine piles supporting the roadway, with 95 percent of components manufactured on land before marine installation.
This engineering project required specialized maritime construction techniques, including the deployment of a dedicated barge named Zourite for component placement.
