bridge at Annonay in 1822, the first wire-cable bridge in the world, and published details in Switzerland. He joined with others to promote a new bridge across the Genevan fortifications, consulting with Seguin on how it might be built, receiving back a series of sketches. Dufour developed the design in late 1822, proposing a two-span suspension bridge using wire cables — this would become the first permanent wire cable suspension bridge in the world. The design used three cables on each side of an iron and timber bridge deck. The cables stretched 131 feet between the towers, although the largest span was only 109 feet.
