history
Since the upper Loire was not without problems for shipping due to its irregular water level, a side canal running parallel to the river was built between 1827 and 1838 . The Canal latéral à la Loire is also the link between the Canal de Briare and the Canal du Center . Inland vessels can travel from the English Channel via Paris and Lyon to the Mediterranean via four consecutive canals .
Under the direction of Jean Joseph Pierre Vigoureux , the engineer Adolphe Jullien built one of the first large canal bridges in France at Digoin from 1834 . It was completed in 1837 and opened to shipping at the same time the canal was opened. In 1870 the bridge was widened. From 1890 to 1896, it was to adjust to the dimensions of vessels of Freycinet class by Léonce-Abel Mazoyer revised again, the water depth was increased by the increase of the trough walls.
