Viaduc de l'Arrêt-Darré

The Arrêt-Darré Viaduct stretches 512 meters across the valley, rising 43 meters above the river with a curved design and a slope of 3.78 percent.

The construction of this engineering structure took place between 1984 and 1987, requiring 12,580 cubic meters of concrete and 1,805 tons of steel materials.

The viaduct represents a significant achievement in French infrastructure development, connecting the major cities of Toulouse and Bayonne via the A64 highway.

Regular safety inspections and maintenance work ensure the viaduct remains a reliable transportation link for vehicles traveling through the Hautes-Pyrénées department.

The structure provides shelter for protected bat species, including the lesser horseshoe bat and greater mouse-eared bat, leading to special conservation arrangements.
