It was also called the Imperial Way due to its high toll that had to be paid in order to use it and that it could host a cart drawn by two oxen one beside the other, a luxury for the time.
Now it is used as an amateur trekking path that runs alongside the Strada provinciale 32MO road and in certain stretches shares the same route.
When the Romans, once defeated the Frinati in 175 BC,[3] managed to settle in the area, they built a thick system of paths and roads.
At the arrival of the Lombards, the road lost most of its importance, though in the 7th century, the Pass of the Radici was opened in order to bypass the remaining Byzantine possessions.
The road was often a matter of content between the free commune of Modena and the Abbey of Frassinoro: the latter was assigned its care officially in 1164 by Frederick I because of the frequent robberies that took place in the nearby Garfagnana.
