was substantially the same as at present, except for the use of the navigable Loire between Briare and Digoin. The introduction of steam haulage and dredging failed to produce the reliability of the canals, so it was in 1822 that the order to build was finally given to the ''Compagnie des Quatre Canaux''. Although the original intention was to place the canal on the right bank, the towns of

and Cosne had no room for a canal and eventually construction started in 1827 on a canal on the left bank. Two massive stone aqueducts were built at Digoin and at Guétin to avoid level crossings of rivers with length 243m and 470m respectively, but this was not possible at Briare because of the danger of blocking the river during flood periods. With the adoption of the Freycinet gauge in 1879, and the upgrading of the canal system, the frequent delays of several days to cross the Loire at Briare became intolerable. The Briare aqueduct was built over the Loire in Briare between 1890 and 1896 by the engineer Abel Mazoyer to make a connection with the Canal de Briare four locks up from its initial entrance. The Briare aqueduct stands on fourteen piers. These support a single metal beam carrying a trough with more than 13,000 tonnes of water, 2.2 metres deep. The width of the aqueduct, towpaths included, is 11.5 meters and its length is 662.7 meters. Eight sluices make it possible to empty the aqueduct in the event of severe freezing.
