Pont de Sully

The Pont de Sully is unique because it is actually two separate bridges that meet at the eastern tip of the Île Saint-Louis. Engineers Paul Vaudrey and Gustave Brosselin designed the structure in the mid-nineteenth century to replace two older pedestrian footbridges that had suffered from neglect and political unrest. One of those earlier footbridges, the Passerelle Damiette, was destroyed during the revolution of eighteen forty-eight, while the other, the Passerelle Constantine, collapsed in eighteen seventy-two after its metal suspension cables succumbed to severe corrosion. The current bridge, which opened in eighteen seventy-seven, serves as a durable cast-iron and masonry replacement that integrates the island into the major traffic routes of the city.
