Pont Saint-Thomas

Pont Saint-Thomas is a cast iron bridge spanning the Ill River in Strasbourg with four parallel arched spans. The hollow arches connect to the roadway deck through cast iron tubular rings that transfer the weight of traffic across the river.

The bridge was built in 1841 by the De Dietrich Company using the innovative Polonceau construction method. It remains one of only two surviving examples of this engineering technique in France.

The bridge connects two city districts and serves as a daily crossing for residents heading between neighborhoods. Its name links to the nearby church that has anchored this corner of the city for centuries.

The bridge is easily accessible to foot traffic and remains structurally sound following its 2008 renovation. Both the walkways and metalwork have been well-maintained, making it a straightforward crossing for pedestrians.

The bridge employs a single-arch design that eliminates the need for supporting pillars in the river. This made the structure more slender and represented a notable technical achievement for its era.
