Information about this scheme

The city of Ulm, with a population of around 120,000, is an important regional centre between Stuttgart and Munich and will soon be the major beneficiary of a high-speed rail line linking it directly with Stuttgart. The new bridge provides an important connection in the new Line 2 tram and bus route being constructed in the city, and spans multiple railway lines whilst also providing a new crossing for pedestrians and cyclists.

The vicinity of the 110-year-old Neutor Bridge required a design that would respect its neighbour and use a similar design language and attention to detail. Designing the new bridge offered the rare opportunity to work in an Anglo- German joint venture on a project in Germany, covering all stages including detailed design, tender documentation and site supervision.

The interdisciplinary work began as early as during the competition stage and the team members communicated daily, ensuring a structurally optimal design without compromising the original architectural ideas. The entire bridge is designed as a continuous 270m steel beam, subdivided into 5 spans ranging between 34 and 75m, which proved to be most economical and most suitable for a launched construction. The variable height of the bridge beams and their sinuous flow add a sense of rhythm to the long structure. It mitigates the impact of the complex horizontal and vertical alignment and, in a playful way, informs about the span lengths and the underlying structural concept.

The highly dynamic vertical movement of the top chord generates an enjoyable experience to the cyclist, as different views towards the city are being hidden and revealed while passing by. For the pedestrian, the bridge deck has been locally widened at the areas of the truss beams. The deck width increases from 4m to 6m providing welcoming rest areas at the end of a long climb. These pulpit- like extensions offering stunning views over the city including the central station and the cathedral. The open triangles inside the truss are equipped with wooden seating spaces inviting users to sit down and relax.

Despite the challenges of limited space, building above live railway as well as a parallel building site for the new tunnel portal underneath, the entire project was delivered on schedule and within the defined budget.
