Approval process

The Gronda di Genova project was thoroughly discussed with the local authorities and the citizens of Genoa. This included the adoption of the Public Debate model in 2009, during which the best design solution was chosen out of 5 different alternatives presented. After finalising the route and optimising the project based on the feedback from the Public Debate, the basic design and related approval process were initiated.
