Completed in 1886 by a student of Gustave Eiffel, the bridge’s top deck is now reserved for pedestrians, as well as one of the city’s metro lines; the lower deck bears regular traffic, as well as narrow walkways for those on foot.The bridge's construction was significant, as the area’s foot traffic once navigated a bridge made from old port boats lashed together.
