The Pont de Bir-Hakeim (English: Bridge of Bir-Hakeim), formerly the Pont de Passy (Bridge of Passy), is a bridge that crosses the Seine in Paris. It connects the 15th and 16th arrondissement, passing through the Île aux Cygnes. The bridge, made of steel, is the second to have stood at the site. It was constructed between 1903 and 1905, replacing an earlier bridge that had been erected in 1878. An arch bridge, it is 237 metres (777 ft) long and 24.7 metres (81 ft) wide. It was designed by the architect Jean-Camille Formigé, who also designed the Viaduc d'Austerlitz, the Jardin des Serres d'Auteuil, as well as the park below the Sacré-Cœur; he also restored the Roman amphitheatre in Arles and the Roman theatre in Orange.
