The Pont de Bir-Hakeim, formerly the Pont de Passy, is a bridge across the Seine River in Paris, France. It connects the city's 15th and 16th arrondissements, and passes through the île aux Cygnes. It was in 1878, for the Universal Exposition, that an original metal footbridge was built on either side of the Ile des Cygnes, and called the "Passy Footbridge". The bridge has two levels: one for motor vehicles and pedestrians, and a viaduct above, through which passes Line 6 of the Paris Métro. The railway viaduct is supported by metal colonnades, except where it passes over the île aux Cygnes, where it rests on a masonry arch. The metropolitan railway viaduct on the top rests on a series of elegant pillars, whose highly ornate decoration unfortunately disappeared when the structure was strengthened from 1930 to 1940. Many commemorative plates decorate the viaduct bridge, including several dedicated to soldiers fallen in Belgium during the Second World War. Called the Passy viaduct until 1948, the work was renamed the Pont de Bir-Hakeim to commemorate General Koenig's June 1942 victory over Rommel in the Libyan desert. It is now included in the supplementary register of historical monuments.
