The Pont Citadelle André Bord forms part of the extension of Strasbourg’s tram line D towards Kehl, Germany. Completed in 2017, the bridge carries two tram tracks as well as pedestrian and cycle routes across the Vauban Basin while maintaining the required clearance for navigation.
The steel arch bridge has a curved suspended deck with a span of 163 metres and an overall width of approximately 20 metres. A single steel arch rises 30 metres above the deck and crosses it at an angle. This unusual geometry responds to the curved tram route and creates the bridge’s distinctive architectural form.
PFEIFER Structures supplied approximately 920 metres of fully locked coil cables together with complementary tension rod systems and project-specific connection components. Two cable planes suspend the curved deck from the arch. Single hangers support the outer sections, while paired cables carry the central section.
The fully locked cables combine high tensile capacity with a compact diameter, smooth external surface and durable corrosion protection. The tension rod systems complete the load-bearing connections and transfer forces precisely into the steel structure. Accurate fabrication was essential because each suspension element had to match the complex relationship between the curved deck and the inclined arch.
The resulting cable system supports the slender appearance of the bridge while safely carrying the loads generated by tram, pedestrian and cycle traffic.
