Hey Russ,
I've noticed this 5-meter wide road (107405595) with front access to multiple residences has been tagged correctly for 13 years. 
While I understand this specific change might be a mistake, there are many reports of narrow residential classifications you've adjusted over the years.
Can we work together to figure this out once and for all? Appreciate your support in resolving this:
