The bridge separates two departments, the Jura and the Ain. "Iron bridge. For several centuries, the Ain was crossed at Thoirette by means of a ferry, known as the bac de Christouphe, the name of the commune where the passenger resided. From 1808 to 1811, the riparian communes clubbed together to build a bridge in place of this ferry. The project had been drawn up by Mr. Cordier, of Orgelet, an engineer then in charge of the direction of the Simplon road works. Various obstacles opposed the execution of this work. It was only in 1829 that an iron bridge was built, which collapsed in 1843. The department of Ain has just replaced it with an iron bridge currently open to traffic". Statistique de la France - 1855 - Ministère de l'Agriculture par Imprimerie Impériale à Paris - p53.

A café in the small village of Thierette. It is a very beautiful place next to the Ain river. It's just over the river and a nice place to take a break.

Between Oignin and Ain there is a small pass, Col de Matafelon (454 m). A short but beautiful descent down to the Ain. At the Oignin there is a swimming area and a small hotel-restaurant Au Moulin du Pont, as well as at the pass.
