I would very much like to see enforced speed limits along the section of the A4 that goes through the WHS. Getting across the road from the Ridgeway (Overton Hill) to East Kennett and the Sanctuary is very dangerous as there is a hump in the road so you can't be seen until potentially too late. Same applies to the crossing point from the Winterbourne path to the walk up to WK Long Barrow - vehicles including heavy lorries go waaay to fast.
PS: Traffic management through the village - not sure how best, perhaps a 20mph speed limit. "Slow Down" signs on the Beckhampton Road where people cross from the NT car park to walk over to Silbury.
