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

The bridge separates two departments, the Jura and the Ain. "Iron bridge. For several centuries, the Ain was crossed at Thoirette using a ferry, called Christouphe's ferry, named after the commune where the passenger resided. From 1808 to 1811, the riparian communes contributed to building a bridge in place of this ferry. The project had been drawn up by Mr. Cordier, from Orgelet, an engineer then in charge of directing the works for the Simplon road. Various obstacles opposed the execution of this work. It was not until 1829 that an iron bridge was built, which collapsed in 1843. The Ain department has just replaced it with an iron bridge currently open to traffic". Statistique de la France - 1855 - Ministère de l'Agriculture by Imprimerie Impériale in Paris - p53.

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/
