The first wooden drawbridge was built here in the mid-19th century, and was replaced in 1869 by a metal swing bridge and pedestrian walkway. As the only crossing point between the town center and the mine’s offices and central workshops, the bridge was very busy at the time, particularly at shift changeover times.
Shortly after the Second World War, the swing bridge became too narrow for automobile traffic. In its place, an imposing riveted steel structure was built at the Le Creusot works, powered by a hydraulic mechanism and an overhead counterweight. This is what you can see today.
