Heading East: You can safely pull off the road here at the Entrance to London brick.
Heading West: Carry on to the roundabout and come back this way and pull in at London Brick.
You can now drive to and park right at GZ.
Stood at the listed waypoint you can see the milestone face down half embedded in the bank of the ditch just ahead and to your left. A sad ending to it's life :(
You do NOT need to cross the boundary into private property to retrieve this cache.
