The road from the top of Winnats Pass to Sparrowpit has “road closed” barriers across half the road at either end to give the impression that the road is closed but at the same time to allow local access.
However it is possible to drive past the collapsed section of road which has a barrier surrounding the hole leaving a single lane past the hole. The road has been partly ploughed (3/4 to full width in general) and gritted was easily driveable by any car except for mini coopers and Lamborghinis.
No doubt the auto insurance companies will use the road closed signs to invalidate your car insurance should you have a prang on that section of road but having “Jesus loves you” stickers on your car will also invalidate your insurance so just drive that section with a little caution.
