Landslipped Road

Anyone local to this? It looks a bit like the Mam Tor road in Castleton, except this one is almost happening in real-time:

My parents used to live at the top of the hill in Lyneham, but have moved again. Luckily there is a good other road

Most of the caves in Wiltshire are slip rifts.

I think there's some bronze age mine workings underneath.

Funnily enough I managed to find it on Google Earth before I really knew where I was supposed to be looking, due to all the ruckling in the fields either side. It does look very interesting - probably not the same cause as Mam Tor, but certainly the same effect. So presumably water is trapped within a clay/gravel mix that is trying to roll down the dip, but is being prevented from doing so by a geological obstruction, and so it's piling up above it? And the road is essentailly now just floating around on top of it.
