Broken bridge in Bonn

 💡 Every day, millions of people cross bridges without a second thought – until one day, a bridge closes and reminds us how much we rely on the invisible foundations of modern life.

🌉 Recently, someone told me that a major bridge in Bonn, Germany – the Rheinbrücke Bonn-Nord – has been closed.



🚗 According to official information, the bridge was closed on 3 June 2026 after inspections found structural damage to the supporting structure. This bridge is one of the most important east-west connections in the Bonn/Rhein-Sieg region, with around 90,000 to 100,000 vehicles previously using it every day. The result: long traffic jams.



🛣️ And honestly, I understand how frustrating this must be for everyone who depends on that route. At the same time, it made me think about something deeper: this is not only a local transport issue. It is a reminder of how much our daily lives depend on infrastructure that we often take for granted.



📗 It also reminded me of my chapter in A Guide to a Healthier Planet: Volume 1, where I discuss how climate change can affect bridges and other infrastructure. I am not saying this specific bridge closure was caused by climate change but I do believe it shows why bridge safety, maintenance, inspections, and climate-resilient planning are especially important due to the climate crisis.



▶️ Writing Chapter 4: “How Climate Change Impacts the Safety of Bridges” of this book changed how I look at bridges. I discuss key points such as:



• Durability risks because of material deterioration and quicker degradation



• Heat-induced damage and risks of long-term deformation



• Accidental load risks and extreme natural event risks



• Geotechnical engineering risks, including higher scour rates, rock fall, soil liquefaction, and clay shrinking



💪 The encouraging part is that awareness can lead to action:

- Traveling long distances by train instead of flying

- Using carpooling instead of traveling in multiple vehicles

- Traveling by bus into the city center instead of traveling by car

- Cycling to work instead of driving by car

- Working from home instead of driving to work by car



🙏 I would also like to acknowledge the valuable work of the researchers cited in this chapter: @Amro Nasr, I. Björnsson, D. Honfi, @Oskar Larsson Ivanov, @Jonas Johansson, @Erik Kjellström. Their work helps connect scientific research with real-world safety and infrastructure planning.



📘 A Guide to a Healthier Planet is also available in German translation for German-speaking readers: “Der Weg zu einem gesünderen Planeten”.
