Millau Viaduc

The Viaduc de Millau in Aveyron is an exceptional French road. A true architectural and technological feat, the viaduct is the tallest and longest cable-stayed bridge in the world.

Overhanging the Tarn from the top of its 343 meters (1140 feet), it allows the junction between Clermont-Ferrand and Béziers on the A75 road. The panorama and the surrounding nature are remarkable.

After 3 years of construction, the viaduct was commissioned in 2004 and celebrated its 10th anniversary in December 2014.

Where is the Millau Viaduct located?

The Millau viaduct is the most spectacular link in La Méridienne road: the A75 motorway, connecting Clermont-Ferrand to Béziers and Narbonne, is the most fluid and less expensive route between Paris and the Mediterranean sea.

Leaning to the north on the Causse Rouge (at the foothills of the Lévézou) and to the south on the Causse du Larzac, the Millau Viaduct crosses the Tarn valley, a few hundred meters from Peyre, one of the 10 “Most Beautiful Villages de France ”in the department of Aveyron. It is of course also very close to Millau, a city of Art and History, the capital of outdoor sports, and the gateway to the Tarn gorges and the Causses and Cévennes territory, a UNESCO World Heritage Site.

Facts about the Millau viaduc:

Description of the road:

It is the highest road bridge in the world (343 meters, 1125 feet). Its deck, which rises 270 meters (885 feet) above the Tarn, was the longest in the world for a cable-stayed bridge (2460 meters, 8070 feet) until the Jia-Shao bridge came into service in 2013. in China. This new structure is 2,680 meters (8,792 feet) long, or 220 meters (721 feet) longer than the Millau Viaduct.

Here are some additional figures, describing a completely non-standard set and an extraordinary technical challenge: “206,000 tonnes of concrete, ie 5 times the total weight of the French aircraft carrier Charles-de-Gaulle fully loaded; 36,000 tonnes is the weight of the steel deck, ie 4 times the weight of the Eiffel Tower; 87 meters (285 feet), it is the height of the pylons, that is to say, a building of 29 floors; 400 million euros is the total cost of the work ”.

Visually, we are not surprised, we are overwhelmed! Downright fascinated by this graceful marriage of nature and technology. The shrouds form a major element of this remarkable aesthetic. They are a strong mark of the viaduct’s identity. Arriving in the area, an image jumps out at us: that of a masterful sailboat sailing on an invisible sea, or moored in a heavenly port.


For a viaduct of this magnitude, it was built in a record time of three years, from 2001 to 2004.
The total budget amounted to 400 million euros.

It was designed by the french engineer Michel Virlogeux and by the english architect Lord Norman Foster.

There were 13 years of technical studies and the site cost more than 2 billion euros
