 It was designed by the engineers Paul Vaudrey and Gustave Brosselin.They set it at an angle of about 45 degrees to the river banks, which means that it gives a splendid view over the quais of the Île Saint-Louis and Notre-Dame.The southern part consists of three cast iron arches, while the northern part, over the narrower arm of the river, consists of a central 42-metre arch in cast iron and two 15-metre arches in masonry.
