If the construction of the Millau Viaduct took three years, the preparation of the project itself lasted 14 years. The very first discussions concerning the crossing of the Tarn river near the Aveyron town of Millau date back to 1987. During the second half of the 20th century, opening up the Massif Central was a major concern. From this issue was born the La Méridienne association, whose role is to contribute to the revitalization and enhancement of the surrounding areas. The first stone of the Millau Viaduct was laid on December 14, 2001.
