The project provides for the rehabilitation of the spaces impacted by the work on the viaduct in order to bring a significant and sustainable improvement in terms of:

• Technical functionality (occasional visit of the viaduct): integrate the implementation of rotatable and accessible access under the arches;
• Establishment of various environments: wetlands, open environments, valleys, etc.
• Sustainable water management: managing water infiltration under construction, modifying the site’s topography and creating soil models;
• Upgrading of urban links: taking into account established customs, unification of the locksmiths' premises, breaking down barriers, etc.
