The Old Bridge in Bourguignon-lès-Conflans is a former road bridge that connected the village of Bourguignon-lès-Conflans in the Haute-Saône department in France with the area of the commune of Mersuay on the other side of the Lanterne . Today the traffic on the D 54 runs over a modern prestressed concrete bridge standing a few meters next to it , the old bridge is at most still used by pedestrians.
The bridge, built in 1849, is one of the oldest still existing cast-iron bridges in France and, alongside the Pont Saint-Thomas in Strasbourg, one of the two remaining bridges that were built according to the system of Antoine-Rémy Polonceau , which he first used at the Pont du Carrousel in Paris applied.
The bridge was listed as a historical monument in 1982.
description
The bridge has two flat segment arches with spans of 24.30 m. The structure consists of three hollow, oval cast iron pipes, which are supported on the abutments and the 2.30 m thick stone pillar in the middle of the river. Since it was much easier at that time to cast pipe halves than bent pipes, sections were made from left and right pipe halves and joined together in such a way that the end of one section was in the middle of the section of the other pipe half. There are rings of decreasing diameter on the arches that support the bridge deck. The road surface consists of cross-laid wooden planks, the railing of cast-iron St. Andrew's crosses .
