Pont autoroutier de Cubzac, Highway bridge in Cubzac-les-Ponts, France.
The Cubzac Highway Bridge is an elevated concrete structure that crosses the Dordogne River on the A10 motorway route. It comprises multiple concrete segments joined together to create a long span that carries constant traffic between major cities.
The bridge was built during the 1970s as part of France's motorway expansion program. A second structure was added decades later to handle growing traffic on this crucial route.
The bridge forms part of the engineering heritage of Nouvelle-Aquitaine region, representing the technological capabilities of French civil engineering during the 1970s.
The bridge carries traffic daily and is easily accessible from major cities on either side. You can view it from nearby roads or stop at rest areas along the motorway to see the structure.
The structure demonstrates an engineering choice to use prestressed concrete instead of traditional steel methods for river crossing. The parallel bridge addition was a clever solution that allowed traffic expansion without closing the original route.
