The Lac de Nantua is a superb body of water of 141 hectares. In the heart of the Jura, it offers an ideal setting for practicing a multitude of sports. It is even possible to swim in its waters.

An impressive work that has its Wikipedia page https://fr.wikipedia.org/wiki/Viaduc_de_Cize-Bolozon

Nestled in a spectacular natural setting, the viaduct offers superb viewpoints over the Ain gorges. Built at the beginning of the 20th century and then rebuilt after the Second World War in 1950, it illustrates the railway and road heritage of the territory.

pretty small stone viaduct with 2 superimposed lanes, one for cars with 6 arches and one for the train with 11 arches. Atypical.

After 7 years of difficult work, the two-arched bridge in Neuville-sur-Ain was put into service in 1777. The construction of the bridge had brought masons and stonemasons from different regions, some of whom came from Beauce seem to have settled and given their name to the hamlet of Bosseron (for Beaucerons). It is a structure listed in the inventory of protected monuments since August 1946. https://www.neuvillesurain.fr/patrimoine-et-tourisme/quartiers-hameaux/neuville-le-bas/
