Bridges and viaducts

Longstanding expertise
For nearly 40 years, our teams have applied their expertise to landmark civil engineering structures worldwide.

Sustainable infrastructure
From valleys to deltas or cities to coastlines, we deliver bridges and viaducts that connect regions and bring communities closer together.

Expert engineering
All the engineers working on our projects have the skills to design complex structures in demanding geotechnical, hydraulic or seismic environments. Using BIM, digital twins and parametric design, we optimise the planning, sizing and execution of projects to ensure precision, safety and durability.

Innovation for decarbonisation
We prioritise low-carbon materials, prefabricated components and the reuse of resources. Through close collaboration, our teams design bridges that are more resource-efficient, lighter and more sustainable.

Dedicated expertise
We provide specialised solutions for bridge construction, including deck launching, cable-stayed systems for long spans, and post-tensioning to control structural behaviour, enhance durability and increase load-bearing capacity.

Longevity and performance of structures
We carry out targeted interventions to extend the service life of existing structures: structural diagnostics, reinforcements, infrastructure upgrades and integration of connected performance monitoring solutions.
Do you have a project?
Let's discuss it.
Whether spanning an urban river, a valley or the ocean, bridges and viaducts shape landscapes and sustainably transform life in the regions they serve.
They connect cities, improve mobility, support the economy and foster human connection.
Beyond the engineering challenge, each project is a reflection of a collective ambition.

For decades, Bouygues Construction has established itself as a leading player in the design and construction of major engineering structures. Our teams have delivered some of the most remarkable bridges and viaducts on every continent, including the Normandy Bridge in France, the new Coastal Road Viaduct on Reunion Island, the Hong Kong-Zhuhai-Macau Bridge in China and the Simone Veil Bridge in Bordeaux, France.
These achievements are founded on recognised expertise in the most advanced construction techniques, including balanced cantilever construction, deck launching, heavy prefabrication and long-span cable-stayed systems. Each project demonstrates our ability to overcome large-scale technical challenges while building functional, enduring infrastructure.
By combining cutting-edge engineering, innovation and aesthetic excellence, we have helped connect communities and shaped landscapes all around the world.
