It is described by a plaque on the side as "Judged the most beautiful bridge of the 18th century", a view shared by the Michelin Green Guide which describes it as "considered to be the finest 18C bridge in France because of its daring design and the beauty of its architectural lines.
"[1] Gignac Bridge has been protected since 1950 as a monument historique by the French Ministry of Culture.
Its dimensions are: length 174.76 m; height 20.64 m; width 9.80 m[2] (respectively, approximately 573, 68 and 32 feet.)
The side arches span 25.97 m each and the central arch spans 50.72 m.[3] Construction began in 1776 to plans drawn up by the engineer Bertrand Garipuy, then Director of Public Works in the Languedoc province.
Delayed by the French Revolution, the bridge was finally completed by chief engineers Billoin and Fontenay in 1810.
