Pont-canal de Barberey-Saint-Sulpice, Canal bridge in Barberey-Saint-Sulpice, Aube, France

The Pont-canal de Barberey-Saint-Sulpice is a cast iron structure that carries a canal across the Seine River, allowing boats to travel above the waterway below. The bridge rests on solid stone piers and features a metal deck that forms a channel for vessels passing through.

Designed by engineer Pierre-Olivier Lebasteur, the bridge was built in 1846 by Hippolyte Cavy of Nevers for the masonry and Jean-Pierre-Victor André for the metalwork, with trusses cast by Rollet & Remy of Joinville. Cast iron let the Haute-Seine canal cross the Seine low above the river, since a masonry bridge would have had to stand higher to avoid damming floods. Two cracked trusses were replaced in iron in 1887, the structure was welded in 1930, and the canal was decommissioned in 1957. Filled in upstream in 1973, it has been dry since.

The bridge is named after the commune of Barberey-Saint-Sulpice, which it links across the Seine. Since 2015 it has carried the Voie verte de la Seine, a greenway open to pedestrians and cyclists, while the canal bed beneath the deck has been dry since 1973. The wooden towpaths that once ran along the channel have disappeared.

The site is easily accessible on foot, and visitors can walk directly across the structure or along a nearby pathway to view it from different angles. The surrounding terrain is relatively flat and straightforward to navigate, making it suitable for visitors of all abilities.

The Pont-canal de Barberey-Saint-Sulpice is the oldest metal canal bridge still standing in France, listed as a monument historique in 1984. Its cast-iron trusses were cast by the Rollet & Remy foundry in Joinville; two cracked trusses were replaced in iron during the 1887 restoration. Since the canal was filled in 1973, the structure has stood dry.
