We don’t just build infrastructure — we connect people, places and possibilities. Our bridges and tunnels service offers a fully integrated range of engineering and advisory solutions that close the critical gaps in road networks.
Whether crossing vast spans or burrowing through rugged terrain, we deliver state-of-the-art designs that merge technical excellence with real-world functionality.
Our multidisciplinary teams leverage the latest international and national standards, designing with precision and purpose. From civil structures to electro-mechanical systems, our expertise covers the full lifecycle of road bridges and tunnels.
Whether conventional methods, NATM (New Austrian Tunnelling Method), or TBM (Tunnel Boring Machines), we tailor solutions to each terrain and tunnel profile. And with advanced launching techniques and innovative materials, Tractebel ensures every structure stands as a model of durability, safety and forward-thinking design.
