Does this path actually exist? I didn't see any trace at the bottom end, and it's not a public footpath either

A horse exercise track has been added here, too recently for the current aerial images to show it. I'll add this when they are updated.

Bridge is in VERY poor condition, only just crossable now

I'm not sure why the previous editor left a gap here, as from the OS map I'm sure the bridleways join together?

As per the note covering the neighbouring land, I don't know what this area is now, but it certainly isn't a golf course!
