The bridge deck is suspended by 154 cables attached to seven reinforced concrete pylons.
The structure was designed by British architect Norman Foster and French engineer Michel Virlogeux.
The deck features a slight curve, allowing drivers to maintain a continuous view of the valley without feeling trapped.
The total length of the viaduct spans 2,460 meters.
The steel deck weighs 36,000 tonnes and was launched using a 'push-launch' technique from both sides of the valley.
The construction was completed in just 36 months, between 2001 and 2004.
The viaduct uses a 'multi-span' cable-stayed design, which was chosen to minimize the environmental footprint in the Tarn River valley.
Wind speeds at the site can exceed 150 kilometers per hour, requiring extensive aerodynamic testing.
The Millau Viaduct Viewing Point is located at the Aire du Viaduc de Millau service area, specifically designed to offer optimal perspectives of the world's tallest cable-stayed bridge. The bridge reaches a maximum height of 343 meters, surpassing the Eiffel Tower. The viewing point is situated on a plateau overlooking the Tarn Valley, providing a clear line of sight to the multi-span structure. The site includes an educational pavilion detailing the construction process and engineering specifications. Visitors can access a marked trail that leads to the 'Belvédère de la Bro de Clapier' for an elevated view of the bridge's P2 pier, the tallest in the world at 245 meters. The infrastructure integrates directly into the A75 motorway network.
The elevated observation platform at the end of the paved walking path.
Walk the short, steep paved path from the parking area to the 'Belvédère de la Bro de Clapier' for the best perspective.
Visit the information center to see the exhibition on the 10-year design and assembly process.
Use the provided binoculars if you wish to see the specific details of the pylon architecture.
Do not attempt to walk along the motorway hard shoulder to get closer to the bridge piers.
Open year-round; exterior viewing areas accessible 24/7, though museum/visitor center facilities operate with seasonal hours.
