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.

Very nice little walk! No particular difficulty for someone who is not sporty (haha) I would just advise against the last descent (at the end) to someone who would be afraid when it is slippery (lots of leaves and stones), in which case take the same passage as on the way there.

From the ruins of Oliferne Castle, perched on a rocky spur in the Jura Mountains, you can enjoy breathtaking views of the Ain Valley and beyond. Once a medieval fortress, its ruined walls and towers now blend into the rugged landscape. Its strategic position allowed it to control access to the region, making it a must-see when hiking the Pic d'Oliferne.
