Renovation Projects of the Year
Manfreida Tunnel Renovation Project

The Manfreida Tunnel renovation, part of the Genoa-Gravellona Toce motorway, adopts the Tunnel Renewal Strategy (TRS), aiming to extend the service life of the tunnel by 50 years. The project involved partially demolishing the existing lining and rebuilding it with innovative materials to improve waterproofing and structural integrity. The renovation is divided into two phases to minimize traffic disruption, using technologies like prefabricated elements and high-performance sprayed concrete. By utilizing a multi-criteria analysis for optimal solutions, the project focuses on safety, minimizing impacts on traffic, and ensuring the long-term resilience of the infrastructure.
