Saint-Cloud Viaduct

The Saint-Cloud Viaduct is a long reinforced concrete bridge that stretches across the Seine River, connecting the districts of Saint-Cloud and Boulogne-Billancourt. Its robust structure carries multiple lanes of traffic on a series of concrete supports that span the river.

The viaduct was built in the mid-20th century to handle growing traffic demands between the two riverbanks. Its completion improved transportation connections and became part of the region's modern infrastructure development.

The viaduct represents French engineering capabilities through its concrete construction methods and architectural design principles of the modern period.

The crossing is accessible by car and carries significant regional traffic flow. Pedestrians and cyclists should stick to designated routes, as the structure is primarily designed for motor vehicles.

The viaduct is one of the longest concrete structures of its kind and showcases postwar engineering innovations. Its design demonstrates solutions for building major spans across a navigable river while minimizing disruption to river traffic.
