The TNR route as we knew it is over.... Bear in mind that the last 100-150km of the route has been affected by the Tende-Roya flood disaster. No idea what the effect is so far but from what I've heard the Col Tende road on the French side of the tunnel has disappeared, Tende itself is cut off from both sides and the road down the Roya valley is gone in places. Repairs will take a long time. The higher tracks will have been out of the flood zone but landslides happen and the ground could be unstable.
The route will need revision some point in the future and until then I'd have to say the current route is unsafe, not recommended.
