1. History and construction of the Millau Viaduct
The story of the Millau Viaduct began in the 1980s, when the French authorities noted the chronic saturation of the RN9 through the town of Millau. During the summer months, traffic jams paralysed traffic between the north and south of the country. The solution gradually became apparent: to create an audacious bypass that would cross the Tarn valley in a single stretch. After years of studies and an international competition launched in 1996, the project designed by Norman Foster and Michel Virlogeux was chosen. These two giants of architecture and engineering designed a structure that was both technical and aesthetic, capable of blending harmoniously into the landscape of the Grands Causses.
Work began in December 2001, involving hundreds of workers, engineers and technicians. Building the Millau Viaduct was a titanic challenge: seven monumental piers had to be erected, the tallest reaching 245 metres, and then the 36,000-tonne steel deck had to be laid using hydraulic jacks. This innovative method involves gradually pushing the deck from both ends until it connects the seven pylons. Each stage is meticulously calculated to guarantee the stability of the whole structure in the face of the violent winds that sweep across the valley. The Millau Viaduct was inaugurated on 14 December 2004 by President Jacques Chirac, marking the culmination of three years’ work and a €320 million investment financed by the Eiffage group under a 78-year concession.
Meeting the technical challenges
To design this giant of steel and concrete, the teams had to overcome exceptional constraints. The deck rests on seven guyed pylons that guarantee its rigidity while giving it a remarkable visual lightness. Wind tunnel tests were used to test the structure’s resistance to winds of up to 205 km/h, ensuring the safety of motorists even in the most extreme conditions. The multi-span design of the Millau Viaduct, inspired by the most modern techniques, has made it a benchmark throughout the world. Even today, engineers and architects from all over the world come to study this achievement, which combines performance, durability and beauty.

From the road leading to La Cavalerie, there are several small car parks where you can stop in complete safety to immortalise the viaduct in its natural setting.
4. Crossing the Millau Viaduct by car
Driving over the Millau Viaduct is a unique and unforgettable experience. This 2,460-metre-long structure is crossed on the A75 motorway, a major route linking Clermont-Ferrand to Béziers. As you travel on the deck suspended more than 270 metres above the Tarn valley, you will experience a striking sensation of floating and weightlessness, enhanced by the visual lightness of the structure. On a clear day, the panorama of the Causses du Larzac, the Causse Rouge and the surrounding mountains is absolutely breathtaking. On the other hand, during foggy spells, it’s not unusual for clouds to cling to the deck, creating an unreal atmosphere where you’re literally flying through the clouds.
Vehicles using the A75 must pay a toll to cross the Millau Viaduct. The toll rate varies according to the category of vehicle and the season. For a passenger car (class 1), the charge is around €12 in normal periods and up to €18 in the high summer season. Motorcyclists and vehicles with trailers are also subject to this toll. You can pay in cash, by credit card or with an electronic toll tag for faster passage.

7. Millau Viaduct anecdotes and records
The Millau Viaduct holds a number of world records that testify to its exceptional nature. With its P2 pylon rising to 343 metres, it is the highest road bridge in the world, surpassing the Eiffel Tower by almost 20 metres. The deck, 270 metres above the river Tarn at its highest point, offers a breathtaking sensation of vertigo as you cross. The construction of this giant required 127,000 cubic metres of concrete, 19,000 tonnes of steel for the piers and 36,000 tonnes of steel for the deck. The seven pylons, varying in height from 77 to 246 metres, support 154 guy wires that ensure the stability of the whole structure in the face of climatic constraints, particularly the wind, which can blow at over 200 km/h in the Millau Viaduct valley.
During construction, there were no fatal accidents, which is a remarkable achievement for a project of this scale. The teams worked in sometimes extreme conditions, suspended dozens of metres above the void. The deck was put in place using an innovative push-pull technique, enabling the 36,000 tonnes to be advanced progressively from the two ends to the final junction, which was achieved with millimetre precision. This delicate operation required several months of painstaking work and complex calculations. Today, the Millau Viaduct is used daily by between 10,000 and 12,000 vehicles, a figure that can double during the summer months. The viaduct has transformed the local economy, attracting hundreds of thousands of tourists every year from all over the world to admire this architectural masterpiece that has become the emblem of the Aveyron region.
