The study is aimed at creating a road system able to improve the road links between the regions of Piemonte and Liguria, which are currently characterized by a high number of accidents and lack of easy mobility (which is a pre-requisite for economic growth).

The identified corridor, where the alternative route proposals are located, extends along the Neva (Savona) and Tanaro (Cuneo) river valleys, starting from near the Albenga junction on the A10 Ventimiglia-Savona motorway and ending near the Ceva junction on the A6 Torino-Savona.

The system under study, which shall supplement the existing infrastructural network, has resulted in the identification of 3 possible alternatives: the project infrastructure consists of 2 distinct carriageways, each one having two driving lanes of 3.75 m and an emergency lane of 3 m.

Layout A

Total length about 19 km; trench road sections 51%; Tunnel sections (natural and artificial) 18%; Viaduct sections 31%; 2 junctions (toll booths); 1 junction to motorway link.

Layout B

Total length about 26.7 km; Trench road sections 17%; Tunnel sections (natural and artificial) 72%; Viaduct sections 11%; 1 junction to motorway link.

Layout C

Total length about 26 km; Trench road sections 6%; Tunnel sections (natural and artificial) 90%; Viaduct sections 4%; 1 junction to motorway link.

The contents of the feasibility study have been developed with a special focus on the following issues:

1) Territorial and socio-economic setting of the corridor, with a special focus on geological, traffic (characteristics and distribution of the network and of mobility infrastructures) and environmental issues (presence of parks and protected areas, watercourses and relevant basins);

2) Traffic study, result of supplementary surveys and simulations related to the considered transport scenarios;

3) Methodology for the development of the routes and relevant alternatives, measurement and geometrization of the infrastructure and works;

4) Technical-economic analysis of the routes and definition of the economic feasibility of the work;5) Analysis

of the main impacts on the environment and territory;

6) Multi-criteria analysis of route alternatives.
