Скачать или смотреть France: Le Pont Canal de Digion

The Digoin Canal Bridge is a canal bridge that allows the Canal Latéral à la Loire to cross the Loire. It allows the side channel to connect a little further with the channel of the Center (Canal du Centre), at the Campionnet port in Digoin. It ends with a lock from which it is separated by a short crossing basin. Only boats or pedestrians have access.

It is one of the first major canal-bridges in France, with 243 meters long. It is the engineer Pierre-Alexandre-Adophe Jullien then aged only 29, who is the author, as well as that of Guétin, under the direction of the engineer-in-chief Jean Joseph Pierre Vigoureux.

Opened to navigation in 1838, at the same time as the canal1, it was expanded in 1870 and it was rebuilt between 1890 and 1896 by the engineer Léonce-Abel Mazoyer as part of the Freycinet channel gauge. It was thus deepened by raising its crowning.
