Thank you @Leigh, sorry to have taken your time unnecessarily. I hadn't expected two of you to respond so very quickly. - Thank you.

Thank you, that was a very quick response!

The road is open since Dec 20, 2019 - Is it possible to revert this change now? (I don't know how to perform that).

Road was reopened on 20th Dec 2019 - https://www.nzherald.co.nz/north-island/news/article.cfm?c_id=1503932&objectid=12305793

This road was re-opened just before Christmas, these changes need someone brighter than me to revert them again to re-open the road please.
