Many local people are incensed that the TdF is using that road over an area which is still pretty wild and has interesting wildlife including protected species.
The road has been used for several years by the cyclosportive "LA VAUJANY" with over 1000 participants which even include a very large number of English, Dutch and Belgian riders, not particularly known on average for their descending skills.
In the downhill part between AdH and Sarenne there used to be sorts of shallow fords, several of them, which forced you to almost come to a stop (20 km/h max). I understand the road has been smoothed out. Anyway, you can look at the Vaujany pictures (Sportcommunication), next edition on june 30.
Best spot around for seeing marmots.
For the col de Sarenne, the road is pretty poor, a good way to keep down the number of tourists.
Apparently it's being improved for the TdF.
Local people believe that the skiing industry people want to extend the skiing domain over that area which should be protected, together with its wildlife.
The local Club Med is on that road, as you leave AdH.
Anyway, the col with the largest number of serious accidents I know of is the Colombière (towards Cluses), yet there is nothing apparently wrong with that road.
Hopefully few spectators will go to Sarenne watch the race.
