Viaduc de Martrou, Road bridge in Rochefort, France.
The Viaduc de Martrou spans 1042 meters across the Charente River, connecting the municipalities of Rochefort and Échillais with a central span of 120 meters.
The construction of this prestressed concrete bridge began in 1989 and concluded in 1991, replacing a vertical lift bridge that had previously served the crossing point.
This infrastructure enhancement modified regional transportation patterns by establishing a permanent connection between Rochefort and the routes leading to Royan and Île d'Oléron.
The bridge spans twelve support pillars and maintains a width of 17.8 meters, accommodating vehicle traffic in both directions without any toll charges since January 2004.
The structure represents a significant engineering achievement, incorporating both shallow foundations and drilled piles to ensure stability in the maritime environment.
