This project involves the improvement of a stretch of the Italian National Road System, in particular the A3 Motorway linking Salerno and Reggio Calabria.
This specific section regards the detailed design of the alternative route of Lot 3 of the A3 Salerno – Reggio Calabria from km 139 +000 to 148+000.
This approximately 10 km stretch of highway situated in a mountainous region is an alternation of 4 tunnels and 4 viaducts. The project concerns the divestment of the existing road and the demolition of its viaducts and the environmental rehabilitation of the former route.
The design include the development of the 3,787 m long Serra Rotonda double lane tunnel, with 6 pedestrian by-passes and 4 driveway by-passes, as well as 5 emergency areas (1 every 600 m).
