 The purpose of the Monte Viso Tunnel was to increase trade by allowing a smooth transition to the merchant caravans that needed to cross the barrier imposed by the Alps.This created a viable alternative to the most dangerous cross country routes, whose difficult crossing caused damage to shipments.In addition, the passage through the tunnel, at a lower section of the passageway, would also increase the useful days for the passage of the goods since, as early as the snowfall, the Col de la Traversette became impracticable.
