Technological innovation

Records broken by the Viaduc de Millau - pylons 245 metres tall

The construction of the viaduct called upon the most advanced techniques used in the world of civil engineering. Before its planning and construction, no site had ever before brought together such a wealth of technology. Laser, GPS, cranes , self-climbing formwork, special surface coatings,  high-performance concrete , innovative materials... all used to make this out of the ordinary structure the engineering marvel it is today.

Several patents were filed during design - concrete or BSI Ceracem, hydraulic cylinders for cranes which helped launch 36,000 tons of steel into the void - the equivalent of five Eiffel Towers.

Several innovations led to time saving in productivity, such as the prefabrication of steel parts assembled on the ground or using self-climbing formwork for the construction of the pylons. These methods have improved worker safety by limiting the time spent working at altitude.

Just three years is a quite remarkable time to build a bridge of this magnitude, yet this is alll
the time it took from foundations to opening.

The Viaduc de Millau has won several international prizes for its outstanding architecture.

A preserved environment

The Millau Viaduct is fully integrated into the the sustainable development policy of the Eiffage group, summed up by the slogan "developing the present to build the future."

Green construction management has limited the impact on the natural environment, based on an implementation study of access roads and production facilities. Only enterprises conforming to ISO 9001 and 14001 were selected for tenders.

The viaduct combines steel and concrete, ensuring a structure that is both slender and strong with a light deck. This promotes the integration of the Viaduct into its environment and limits the ground contact points to just seven pylons. Five thousand truck deliveries were saved by prioritising prefabricated elements.

An unmissable sight

The multi-cable stayed viaduct, the tallest in the world, is a symbol of modernity. An architectural feat signed Norman Foster and Michel Virlogeux, its elegant silhouette is part of the wonderful landscape of the Causses. The public continues to pour in to discover it and the great and the good of the world over come to marvel at its prowess.

Each year more than 500,000 people come to see the structure from all angles.


VIADUCT INFOSPACE: Who better than the constructor to help you discover the viaduct?

An official visit area dedicated to teaching the public how this giant was built, of what it is made and all the secrets of its construction!
At the foot of pyon 4, the Viaduct Infospace welcomes you every day:

  • 10 am to 7 pm April to October
