This is a photo of the new road and roundabout (Green arrows) for general traffic. The racing cars will still used the old bit of road (for how long I wonder). However the old viewing area (that famous little hill) is no longer available. At least this is my understanding.
That certainly will take something away to the pleasure of watching the cars from behind accelerating. Especially at night.
Obviously the road planners are not race enthusiasts.
I shall write and complain to the ACO (my club) and suggest they erect a stand where the old viewing area was.
