Antoine-Rémy Polonceau (1778-1847)

Polonceau is best known for his patented method of bridge construction, which features wooden arches covered by cast iron plates. It was first used on the Pont du Carrousel in Paris. The arches were of nominally elliptical cross-section with a major axis of 0.6m and minor axis of 0.32m. The wooden arches were laminated with eleven boards 55 mm thick, and contained within thick cast iron plates 37mm thick, with bolted flanges top and bottom. The gaps were filled with nitumen. Work on the bridge commenced in November 1831, and was completed October 1834.

Bridges of that type built in France are listed below.

Pont du Carrousel, Paris - 1834 - 1936. Three cast iron spans of 47.66m
Pont d'Erdre (metal) Nantes - 1840
Pont du Corbeau (metal) Strasbourg - 1842 - 1892
Pont Saint-Thomas (metal) Strasbourg - 1841 - to date
