Since the early 1960s, most of the motorway network in France has been built under concession schemes, primarily by six public and one private concession companies. Until the year 2000, the extensionof the motorway network was granted to the existing concession companies and the new motorway sections were financed by revenues of the existing sections of the network. This system is called "adossement" European regulations have now banned forbidden this practice and it is compulsory for the grantor(the State) to issue a tender in order to select the concessionaire of new motorway sections.
