Our design concerns the road infrastructure needed to integrate the existing road network with the Bridge over the Messina Channel: 10.5 km in Sicily (of which approx. 67% in tunnels) for connection to the motorways A18 Messina-Catania and A20 Messina-Palermo; 9.8 km in Calabria (of which approx. 64% in tunnels) for connection to the new route of the A3 Salerno-Reggio Calabria motorway.
The infrastructure identified is the result of a number of discussions and optimizations that can be grouped into the following macro-categories:
1) Consistency of the design with the rules concerning the design of road infrastructures, with special focus on the safety standards for new motorways.
2) Optimization for construction purposes, since the route mainly develops in tunnels and, therefore, the underground works are a key element for the feasibility of the work, both in economic terms and with regard to the relevant construction time.
3) Implementation of the suggestions coming from the territory: following meetings with the municipal authorities involved, a number of territorial consequences of the proposed route have arisen that made it necessary to modify some significant sections of the road from a planimetric and altimetric perspective.
