Pont de Poissy

The Pont de Poissy is a steel and concrete bridge spanning the Seine between Poissy and Carrières-sous-Poissy. The structure provides clear passage for river traffic while supporting road vehicles across its main span.

The bridge opened in 1952 to replace a stone structure destroyed during the Second World War. Its construction marked the region's return to normal functioning after years of wartime disruption.

The bridge connects two communities and shapes the river valley landscape with its modern steel design. It remains part of everyday local life, showing how the region rebuilt itself after wartime destruction.

The bridge is open daily to pedestrians, cyclists, and motor vehicles, offering direct crossing of the river. Access is unrestricted from both riverside neighborhoods.

The bridge is supported by numerous concrete piles driven deep into the riverbed, creating a hidden foundation beneath the water. This underground engineering allows it to remain stable despite constant river movement and seasonal water level changes.
