Yes, but on looking back it appears that both were on the Rue d'Italie, which would prevent approaching from the east as we would be doing to arrive from Montgenèvre, as then you'd have to travel through the finish in the opposite direction on the way into town, unfortunately. Back then (and in the 2009 Dauphiné also, which came through the old town like the Giro) they went out of the old town and swept right through the roundabout - I just checked the 2007 Giro stage finish and they took a wide, sweeping right suggesting they went along the roundabout onto Rue d'Italie rather than into the parking area, and they were about 75m from the line coming through that final corner, placing the finish right near the end of the Parking, which was used for logistics, podium, officials' cars etc.. It would be possible to do use the parking area as a road - it is wide enough - if approaching from the east, tightening up the final corner so as not to return to the Rue d'Italie, but this would remove the option of using this as the diversion for course cars/bikes, and potentially also reduce the distance from the final corner to the finish depending on how much run-off they need. They'll probably also need to remove the road furniture entering the parking because otherwise it would be extremely narrow, although for a Grand Tour this is probably fairly easily achievable.Wasn't the finish line at the exact same spot for both the Giro and the Tour in 2007?
This problem is avoided by using the Tour finish because they can use Chemin du Barry as the diversion, place the finish before the roundabout on Avenue Baldenberg, and keep the logistics in the parking area as they did in 2007. The Giro/Dauphiné finish would be preferable, for sure, and the problems relative to 2007 and 2009 aren't insurmountable, but it would require a bit of manoeuvring.
