One of the three viaducts on the A89 in the canton of Eygurande. A technical and aesthetic feat, the Chavanon viaduct is 360m long and overlooks the wild valley of the same name. A link between the Limousin region (commune of Merlines) and the Auvergne region (commune of Messeix), it uses a revolutionary technique unique in Europe: a suspension bridge with two axial cables and two 70m-high inverted V-shaped pylons.
