The Pont Saint-Thomas ( Thomasbruck in Alsatian , Thomasbrücke in German) is an iron arch bridge that crosses the Ill in the Finkwiller district of Strasbourg ( Bas-Rhin department ) . The cast iron structure was erected in 1841 by the de Dietrich brothers from Reichshoffen with Nicolas Cadiat as chief engineer according to the plans of the engineer Antoine-Rémy Polonceau , who designed the Pont du Carrousel in Paris in the 1830s.

It is one of the oldest existing cast iron bridges in France.

location

The bridge is located in the course of the rue Martin-Luther leading from Place Saint-Thomas . On the other bank, it flows into Quai Finkwiller and Quai Charles Frey .

history

The existence of a St. Thomas Bridge has been proven since 1197. It was one of the nine wooden bridges that led from the city center over the main arm of the Ill to the south. In the course of history it changed its name several times. After the French Revolution it was called Pont de la République, only to become the Pont Saint-Thomas or Thomasbruck again in 1813 .

In 1841 a new building was erected that still exists today. After the Franco-Prussian War , it was given a German name in 1871, and again the French name after the First World War . During the German occupation of Strasbourg in World War II , the German name was ordered, after the war the bridge was given its French name back.

The building has been a listed building since 1995 .

description

The bridge has only one arch with a span of 31.10 m. The absence of piers made it possible to narrow the river bed somewhat at this point in order to later create a new embankment. The structure consists of four hollow, oval cast iron pipes that are supported on two strong abutments that were founded on concrete. 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. In contrast to the Pont du Carrousel in Paris, the pipes remained empty. There are rings of decreasing diameter on the arches that support the bridge deck. The bridge deck was made of iron, but was replaced by a reinforced concrete slab in 1958.
