The Pont de Bercy has the appearance of a Roman double-deck aqueduct. It replaced an inadequate suspension bridge in 1864. It was originally just a five span, stone masonry, spandrel-filled arch bridge (the lower structure in the photograph). However, in 1904, a second deck was added to carry the Metro line. In 1986 the bottom deck was widened (using reinforced concrete with a stone facade) to carry more traffic while matching the original structure.
The current structure has six traffic lanes (three in each direction) along with wide sidewalks on the lower deck. The bridge is 175 m (575 ft) long and 40 m (130 ft) wide. It carries Boulevard Vincent Auriol and Boulevard de Bercy across the Seine and provides a link between the two arrondissements in the southwestern part of Paris. You would see the Passarelle Simone de Beauvoir (named after the feminist writer) just behind the Pont de Bercy, except it hadn't been built when I took this photo.
