 The scheme involves the doubling of the A47 between Saint-Etienne and Lyon, more precisely between Pierre-Bénite and Fouillouse.The project was instigated as a result of a debate held in 1993 rejecting a project to enlarge the A47, as it was concluded it would be too difficult to widen the A47 where it crossed through two communes, Givors and Rive-de-Gier.Additionally, there was a need for an alternative motorway to the A47 in the event of serious accidents or heavy traffic.
