Viaduc de Nantua, Highway bridge in Nantua, France
The Viaduc de Nantua extends across 1003 meters with concrete pillars reaching heights of 77 meters above the Oignin river in eastern France.
The construction of this dual-carriage bridge occurred in two phases, with the first section opening in 1985 and the second completed in 1996.
Architect Maurice Novarina incorporated regional architectural elements into the design, reflecting the engineering capabilities of late 20th century French infrastructure.
The viaduct serves as a critical segment of the A40 motorway connecting Mâcon to Annemasse, emerging directly from the Chamoise tunnel.
The bridge structure consists of ten carefully engineered pillars, each constructed using climbing formwork with foundations extending up to 21 meters deep.
