Cahors Railway Bridge

This railway bridge was built on the Montauban-Brive line, an axis declared of public interest because it corresponded to the shortest route between Toulouse and Paris. Built at an angle to the riverbed, it combines traditional techniques and implementations typical of industrial architecture.The structure was built between 1880 and 1883 by the engineers Jean LANTEREIS and Jean-Louis LACAZE, employed by the Fives-Lille company. It consists of 5 arches with an opening of 36 meters. The pillars decorated with pilasters are made of hewn Cantal granite. The industrially manufactured metal trusses were melted down in the Fourchambault workshops on behalf of the Orléans company and transported to the location by rail.

From the builder of the Eiffel Tower

According to my research this bridge has nothing to do with Eiffel.
The history of the Cahors railway bridge is intertwined with that of the Montauban-Brive line. Declared of public utility by the law of March 11, 1879, it was of capital importance because it was the shortest route between Toulouse and Paris. A first section between Montauban and Cahors led to the construction of several structures: bridges over the Tarn and Aveyron, viaducts and bridge over the Lot. The construction of the latter was entrusted to the Fives-Lille Company. The work, supervised by two civil engineers: Jean Lantereis and Jean-Pierre Lacaze, began in March 1880 and was completed in June 1883.
