tomorrow we will commemorate the fall of the Berlin Wall but here in Italy has just dropped another wall, the Tuscan-Emilian Apennines.
Right now, it's cutting down the last wall of rock of the last tunnel of the "Variante di Valico," the tunnel "Val di Sambro," a 3,866 m long tunnel.
So, after years of work, the section between Bologna and Florence of the A1 Milan-Naples is upgraded.
In 2006 he completed the modernization of the section between Casalecchio and the hamlet of La Quercia, with the widening of the existing highway, the construction of the two tunnels "Ceretolo" and "Calzavecchio "and realignment with the new viaducts " Reno "," Lama di Setta "," Vado " and" Campolungo "and the new tunnels natural" Monte Mario "," Allocco "," Vado "and" Campolungo " with the reconstruction of the junction of Sasso Marconi and with the creation of artificial tunnel "Gardelletta."
Between 2007 and 2013 have been completed the modernization of much of the section of Florence.
In 2007 it was also remade the release of Barberino di Mugello.
Now, we are completing the most important part, that of the Apennines.
The works are the symbol the tunnels "Val di Sambro," "Sparvo" and "di Base."
To make the tunnel "Sparvo" ( length 2,574 km) is served a drilling machine of enormous size, "Martina."
He had to resort to this because of the presence of gas underground.
The tunnel "di Base", however, is a 8.6 km long tunnel who is on the border between Emilia Romagna and Tuscany.
After years of work (eighteen to be exact) the problem of a highway that the 2003-2013 saw more than twenty thousand accidents has been resolved.
Despite the demagogic claims, the work went on, and next year we will have safe and modern highway.
This happened in the 50th year of the A1 Milan-Naples motorway.
