In the 1860s the joint venture between J.F. Cail and Fives-Lille (cf above) was also effective in bridge building. In 1864 it built the Viaduc de Busseau of 56.5 m height. In 1866 the joint venture finished the Pont de l'Europe made of Structural channels and sheet metal. In 1868-1869 it built the Viaduc du Belon and the Viaduc de la Bouille for the railroad from Gannat to Commentry. The joint venture also built part of the main building of the Exposition Universelle (1867)
