If your software is using highway=construction for navigation, try adding access=no instead of deleting the road.

Why did you disconnect the footways from the road?

I can see how "left|||" can arise from a typo, which must be why KeepRight flagged it, but in this case it was correct. I changed it from empty values to explicit ones to help clear things up. I also found that the roads running north-south through that intersection had actual mistakes in them. Thanks for helping out!

What was the error you were trying to fix? There are four lanes at this point, but you changed the turn lane tagging to only account for three.

Thanks for your contributions! A separate node is not necessary when the building is already tagged.

It was previously decided by another editor (who does addressing for their job), that the number prefixes on the street names was not necessary (especially now with the individual address points), and actually complicates the address navigation. e.g., the full address is written as 204 Spring Haven Court SE, not 204 200 Spring Haven Court SE. This is one instance where a digital map will differ from the physical signage.

I would love to get the Airdrie Open Data into OSM! I haven't seen any mentions of your plan on the mailing lists though, have you looked at the import guidelines? osm.wiki/Import/Guidelines
Hope we can work together on this!

Thanks for the explanation :) I guess what was planned is not what happened then, because all the signage was made without a space, and the Vesta Properties website also advertises it as "Southpoint": https://www.vestaproperties.com/community/southpoint/

What is NSP? The street signs that I surveyed did not have a space.
