A406 - The Saone viaduct - Macon southern bypass
Mis en service en mars 2011, le contournement sud de Macon (A406 - France) relie l'A40, a l'est, au noeud RN79-RN6-A6, au sud de la ville. APRR, maitre d'ouvrage, et son maitre d'oeuvre EGIS se sont appliques a faire de ces 9 km d'autoroute une realisation exemplaire, ou les exigences du developpement durable sont prises en compte a tous les stades de la conception et de la realisation. Fonctionnel et neanmoins harmonieux, le viaduc de franchissement de la Saone temoigne qu'il est possible de concilier l'economie et le respect de l'environnement. ABSTRACT IN ENGLISH:The A406 motorway crosses the flood plain of the Saone River downstream of Macon city. The 450-metre, seven-span viaduct crossing the river forms part of the flood discharge system. The two beams of the composite-structure deck are connected by transverse girders that are extended by cantilever girders under the edges of the slab. The slab was concreted over structurally participating formwork which contributes to its strength. The frame was launched from the embankment on the right edge, built on rigid inclusions passing through the compressible soils. The bridge was designed in accordance with the French design code of 2007, but execution was verified in accordance with the new earthquake resistance codes and the Eurocodes, under preparation at that time. By using large-sized hooped rubber support systems, it was possible to keep the originally planned foundations. The total weight of the frame increased 7.5%, from 2210 to 2375 tonnes.
