Road Infrastructure
6 Torino-Savona
The Torino-Savona, which crosses the Colle di Cadibona, a mountain pass between the Po Valley and the Ligurian coast, required considerable effort due to the turbulent topography and adverse geological conditions that characterise a large part of its route.
For this reason, there are numerous road structures along the route that require considerable maintenance efforts. Below is a summary of the main works along the entire length of the motorway.
