The street identified in red in the attached graphic is not a public street but is a private access drive and should be removed from the map.
I would like to note that the sign on the corner was probably not put there by the city but by a resident, so it’s most likely no more private than where the road connects to NW Grant Ave.
However, because it is significantly narrower, I have made it private to reduce the chance of traffic getting traffic going in both directions.
