The operation is a strategic study of the coordinated development guidelines for the Saône ports of commerce in the Burgundy Franche County region in coherence with the current public spatial planning policies, in particular the Regional Plan for Sustainable Development and Equality of Territories (SRADDET). This study will constitute the collective spatial planning project on this network of ports and the action plan to be carried out by 2030. More specifically, the challenges concern the development of multimodality in particular that of inland freight transport, economic development in particular endogenous growth within ports, optimisation and/or rationalisation of investments.
