Theme: Adapting Tunnels for Tomorrow
The tunnels we use today were built for another time. Yet, we must ensure they remain safe, reliable, and resilient in a rapidly changing world. Extreme weather, shifting mobility patterns, and geopolitical uncertainties challenge our infrastructure in new ways.

This theme calls for innovation and collaboration:

• How do we future‑proof both new and existing tunnels?
• How do we adapt infrastructure to events we cannot fully predict?
• And how do we ensure European knowledge flows freely across borders?
