The Moulins (Allier) railway bridge in Moulins serves the railway line in the Allier département in the French region of Auvergne-Rhône-Alpes that now only runs to Souvigny, previously via Commentry to Montluçon .
It crosses the Allier and its flood bed as well as the Quai d'Allier - Boulevard de Nomazy .
In Moulins it is often only called pont de fer ( iron bridge ) or pont noir (black bridge) in contrast to the stone Pont Régemortes for road traffic.
Founded between 1857 and 1858 by JF Cail & Cie. The bridge built was influenced by the Asnières railway bridge, which was only five years older , but its structure no longer consisted of a complete box girder . Instead , the 332.5 m long bridge has two high wrought-iron solid wall girders , which are arranged at a distance of 8.60 m, connected by cross girders and stiffened with diagonal braces. The girders rest on 8 double pillars. The round pillars, each 2 m thick at the top and 2.5 m at the bottom and connected by St. Andrew's crosses , consist of cast-iron pipes filled with concrete, which were later secured with steel straps. When the bridge was built, the pipes served as caissons . The bridge has 7 bridge fields with pillar spacing of 42 m and 2 edge fields of 19.25 m. The originally wooden bridge deck was replaced by a steel structure in 1946.
