From Note 1034329: "Does it matter that the gate is right beside the traffic lights at the Grange Road - Harlods Grange Road - Kellystown Road - College Road junction?"

If you can position the gate on the map more accurately, I'd encourage you to.  The overhead imagery obscures the gate itself, so I didn't actually move it in changeset #49585862. I just connected it to the paths.  The iD editor is quite easy to use.
