This bridge-canal over the Loire was built in four years from 1890 to 1894 by 2,000 workers to allow the crossing of the wild river and facilitate commercial navigation to Paris.
Given the length and weight of the water (13,000 tonnes), a metal structure was chosen for the Briare Canal Bridge. More precisely, mild steel with a low carbon content, which is more
Gustave Eiffel's workshops, which at that time were building the Tower of the same name, were involved in part of the construction of this structure. They contributed to the foundations and the
14 stone pillars that support the metal part, spaced 40 metres apart.
The Briare Canal Bridge is 662.69 metres long, making it the longest metal bridge in Europe.
Its width of 11.60 metres does not allow boats to pass each other, so it was necessary to wait for the passage in one direction and then in the other to cross. At the end of the 19th century,
about thirty boats passed by every day.
