This is a small roundabout

This is not how the road is structured. Its hard to explain but there is a road that also goes straigh from ovenden road onto combe bank drive.

pretty sure those are not there anymore (suggested by the satelite imagery), and even if they were, they're not public, I couldnt find any way of accessing them without jumping over gates.

This is not a footpath. This is just the edge of the park, that a lot of people walk along.
