Pont de Seyssel, Cable-stayed bridge in Seyssel, France

Pont de Seyssel is a cable-stayed bridge 220.60 metres long crossing the Rhône between the communes of Seyssel in Ain and Seyssel in Haute-Savoie. A single light-grey concrete pylon rises from the deck, and thin white cables fan out from its upper part down to both sides of the roadway. A rectangular opening pierces the pylon near deck level, and a sign on the deck reads "le Rhône".

The first bridge at Seyssel was a suspension bridge built in 1840, replacing earlier wooden crossings that had collapsed. The present cable-stayed bridge was completed in 1987, carrying the deck on cables fanning from a single concrete pylon. It spans the Rhône between Seyssel in the Ain and Seyssel in Haute-Savoie, a total length of 220.60 metres.

The bridge links two communes that share the same name, Seyssel, one in Ain and one in Haute-Savoie. A sign on the deck marks "le Rhône", and another announces "SEYSEL" with a diagonal line, the end of the built-up area on the Haute-Savoie bank. The two Seyssels remain separate municipalities on opposite banks.

The bridge is open to regular vehicle traffic and allows visitors to cross between the eastern and western riverbanks. Pedestrians and cyclists can also use the structure to traverse the Rhône.

The bridge carries a sign reading "le Rhône" on its deck, and a sign above the roadway marks "SEYSEL" with a diagonal line, indicating the end of that place's boundary. The single concrete pylon has a rectangular opening near deck level, through which the roadway passes.
