On March 19 and 20, 2025, the Dresden Bridge Construction Symposium took place under the direction of Prof. Dr.-Ing. Steffen Marx at TU Dresden. Experts from the bridge construction industry exchanged views on current developments and technologies. A team from CSZ was on site to gain valuable insights and new ideas. In seven short answers, the CSZ team reveals which impulses from the symposium will be decisive for future projects.

1. Which topics at the bridge construction symposium did you find particularly important for CSZ?
“The insight into the work of our colleagues from the industry was particularly interesting for us. The state of the infrastructure and the government’s announced investment package, which at 500 billion euros for infrastructure and climate protection comprises a considerable volume, were discussed intensively. The preservation of existing bridges is a top priority for all project participants.”

2. What does CSZ take away from the symposium to improve future bridge construction projects?
“The topic of structural diagnostics is still a decisive factor. Especially after the tragic collapse of the Carola Bridge, we have to continuously question and optimize our work processes and the care we take when inspecting and repairing bridges. We must be aware of this responsibility, but at the same time remain open to new building materials and innovative solutions that improve bridge construction in the long term.”

3. Were there any new technologies or materials that you found interesting for your work at CSZ?
“The exhibition of over 100 exhibitors provided an excellent opportunity to discuss the latest products and technologies. We found the dialog with the companies Huesker and Mageba particularly exciting. The increased use of carbon in bridge projects, for example in arch bridges with carbon cable hangers, is a technology that offers us a lot of potential for future projects.”

The Dresden Bridge Construction Symposium 2025 not only offered a deep insight into current challenges in bridge construction, but also into innovative solutions and sustainable approaches. The focus was particularly on increasing the efficiency of projects and integrating new technologies and materials. CSZ draws valuable inspiration from the discussions and presentations to make future projects even more sustainable and resource-efficient.

4. What challenges in bridge construction were addressed at the symposium?
“The focus was on hydraulic engineering aspects, flow dynamics and flood protection, particularly with regard to more frequent flood events. The prioritization of renovation projects (paths, bridges, routes) was also discussed in depth. It is crucial to always keep an eye on the economic viability of both individual projects and the entire infrastructure.”

5. Were there any new ideas for increasing efficiency in bridge construction that are relevant for CSZ?
“The presentation of sample and type designs for several locations is particularly relevant for us. They enable a more efficient use of resources while maintaining high quality and adaptability to different conditions.”

6. How does CSZ deal with the issue of sustainability in bridge construction?
“Sustainability is central to our work. We focus on renovating existing bridges instead of building new ones whenever possible. Our bridge designs make it possible to separate building materials by type during demolition in order to promote their reuse and reduce CO2 emissions.”

7. Which projects at the Bridge Construction Prize 2025 inspired you in particular?
“The Chemnitz Viaduct, which was preserved as a landmark thanks to the involvement of the citizens, was particularly inspiring. We were also impressed by the Oder Bridge in Küstrin, which uses advanced technology to create a symbolic link between two countries. The New Rain Bridge in Roding impresses with its successful design and the optimization of material requirements – an example of modern, efficient bridge planning.”

Conclusion
The Dresden Bridge Construction Symposium 2025 provided CSZ with valuable impetus for future projects. The discussions about infrastructure, innovative materials and sustainable renovation approaches will continue to shape the company’s work. CSZ remains open to new developments and implements these findings to make bridges more efficient, sustainable and safe.
