 Access to the tunnel is still occasionally obstructed by rockfalls, but the route is now an established link within the network of mountain paths in the Monte Viso-Queyras-upper Po valley district, as an alternative to crossing the summit of the Col de la Traversette.After major tunnel reinforcement works, the new reopening of the tunnel was inaugurated again on October 15, 2014.Located at an altitude of 2,882 metres in the East-West direction and 80 metres below the crest of Gran Grano, the tunnel originally measured about 100 metres long while it is currently about 75 metres due to the erosion of the mountain sides.
