Thank you for your quick reply :)

It is nice of you to join us. 

Since personnell and others with business there are allowed on that road the tag "private" is a better fit.

If you know of missing gates, feel free to add them at the proper spot of the highway.

If you have any questions, please reach out. Many active NorthAmericans can be found on slack. There's also groups on Signal and the Forum at c.osm.org

Nearly everything is explained in our wiki at wiki.osm.org
