2019 Update:

Coming from the Italian village of Limone Piemonte you can reach the top as usual. Unfortunately directly at the border with France there is a strict driving ban - even though that there is no police to check that. On 2017 there was a landslide on the French side which made it impossible to pass the road by cars or heavy motorcycles. This landslide does not block the street anymore. Unfortunately on 2019 there is another problem. This road was passed by one of the first long mountain tunnels in the Alps. This tunnel has just one traffic lane so there is a traffic light on each end to enable a one way traffic which changes every 15 minutes. This is going to change because currently they are digging a second tunnel. The construction works are ongoing on both sides of the mountain and of course there is a building area on both sides. On the French side the old road crossing the pass ends in this building area and it is not predictable if the end of the road is not blocked by any building material of construction machines. Even if not there is a high fence around the building area with a door with is closed at minimum of the weekend. So chances are currently good that you have made this fantastic road and immediately, at the end, you have to turn around and drive back the whole distance and cross the mountain via the tunnel anyway.
