Pont d'Argenteuil, Road bridge between Argenteuil and Gennevilliers, France

The Pont d'Argenteuil is a road bridge over the Seine whose 232 m length includes three steel arches of 62, 68 and 62 m, carrying a 19 m deck between stone piers. Each arch is formed of six riveted curved girders braced diagonally and transversally, with slender unornamented props lifting the roadway above them. Flower boxes line the railings and small potted trees stand on the walkways.

A ferry, marked on the Cassini map, once crossed the Seine here. A first bridge, built in 1822, was destroyed in the war of 1870 and replaced by a wooden footbridge painted by Alfred Sisley. The 1874 cast-iron bridge, depicted by Claude Monet, Auguste Renoir and Gustave Caillebotte, was destroyed in 1940; the present steel bridge dates from 1947.

The bridge has been painted by Claude Monet, Auguste Renoir, Gustave Caillebotte and Alfred Sisley, who depicted the wooden footbridge that preceded the 1874 cast-iron structure. The first stage of the 1919 Tour de France started from the bridge. Its railings are decorated with rows of flower boxes, and small trees in planters stand on the walkways.

The bridge carries the D909 between Avenue d'Argenteuil in Gennevilliers and Avenue Gabriel-Péri in Argenteuil. Since its 2020–2021 reconfiguration it has a two-way cycle lane and wider pavements, with one car lane removed; dynamic signs reverse a lane towards Paris or the Val-d'Oise at peak hours. Flower boxes line the railings.

The 1947 steel arches follow the style of the Pont d'Asnières, but their slender supports were left undecorated, so the framework stays visible from below. Each of the three spans is formed by six riveted curved girders braced diagonally. The bridge also crosses the four-lane Quai de Bezons on a short adjoining structure before reaching Avenue Gabriel-Péri.
