Pont de Luzancy

Pont de Luzancy crosses the Marne River using three identical box girders made from tubular prefabricated concrete segments. The structure spans 55 meters and sits on Route D402, connecting the villages of Luzancy and Méry-sur-Marne.

Engineer Eugène Freyssinet designed and built this bridge in 1946 following the destruction of the previous crossing during the Second World War. The project was part of France's post-war reconstruction efforts.

The bridge represents a significant advancement in civil engineering as it was the first prestressed concrete bridge built in France.

The bridge is accessed via Route D402 and is open to vehicles and pedestrians for daily crossing. Best visited during daylight hours to observe its structural details from both approaches.

The central section of each box girder is held in place by cables connected to tall masts that rise about 23.5 meters above the bridge. This structural approach was one of the first applications of prestressed concrete technology in France at that time.
