The Canal Latéral à la Loire was constructed between 1827 and 1838 to connect the Canal de Briare

at Briare
Briare
and the Canal du Centre at Digoin, a distance of 196 km. It replaced the use of the River Loire which had reliability problems arising from winter floods and summer droughts. Aqueducts were used to cross the River Allier

at Digoin, but because of the extreme length required, one was not built to cross the Loire River

until 1896 when the Briare

History[edit] By the late 18th century with the completion of the Canal du Centre, the Bourbonnais route

Seine
to the Saône
Saône
was substantially the same as at present, except for the use of the navigable Loire between Briare
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 Nevers, la Charité 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
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
Briare
became intolerable. The Briare
Briare
aqueduct was built over the Loire in Briare
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
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. En Route[edit]
