The Garfagnana
The Road Vandelli, La Via Vandelli
In brief.

Between 1739 and 1752 the Duke of Modena Francesco III built by the "mathematical" Domenico Vandelli a road to connect Modena Massa, through the Tuscan-Emilian Apennines.
Marriage Cybo-d'Este, established in March 1738 and celebrated in April 1741 for the dynastic interests of the Este family in Modena providing an outlet to the sea, was the reason for this route of communication with Tuscany.
It seems that the road was actually built for military purposes, to move troops and towing cannons in the capital of the Duchy and the Tyrrhenian Sea, rather than links to civilians; was instead presented as road and commercial, in part to make it pay the local community.
The old eighteenth artery was called "Road Vandelli" ("La Via Vandelli") from the name of its designer. This road still exists.
More or less preserved, for large stretches of the Tuscan-Emilian Apennines.
