This iron bridge was destroyed in 1930 and replaced with a concrete bridge, also with three arches. The circular cast iron elements in the bridge are clearly seen.

Begun in 1831 in the extension of the rue des Saints-Pères on the Left Bank, the original bridge was known under that name until its inauguration, in 1834, when king Louis-Philippe named it Pont du Carrousel, because it opened on the Right Bank river frontage of the Palais du Louvre near the Arc de Triomphe du Carrousel in front of the Tuileries. It was destroyed in 1930; the rebuilt bridge is concrete with three arches as well. In 1830 and 1831 Polonceau registered two patents for building bridges in iron and cast iron, which he put into effect in a Parisian toll-bridge (1831-1834; rebuilt 1939), and the Pont du Carrousel, connecting the Quai du Louvre and the Quai Voltaire. His 'system' depended on the use of hollow, cast-iron, elliptical arches, thus ensuring the lightness, solidity and economy of the structure.
