Project Introduction
Within the context of general improvements to the A1 Milan-Naples highway, the A1VAR Variante di Valico has a considerable strategic significance for travel between the North and South of Italy along the Apennine section between Emilia-Romagna and Tuscany regions.
The Valico Variant is nearly 63 km long. Thanks to the addition of new lanes in each direction and the construction of new stretches, it will greatly improve driving conditions and reduce travel time between Bologna and Florence, thus providing comfortable and safe journeys to those travelling for both leisure and work.
Spea designed and is supervising the construction works of the entire section.
In particular, tunnels with length over 2000 m , many of which are natural tunnels, represent the 50 % of the total length of the project. They have been implemented with traditional technique or mechanized excavation (Tunnel boring Machine). Below is the list of tunnels and their characteristics:
