text: Yeah, I think you're right here. Being unpaved, this might be a private right-of-way... I wonder if there's any "private" signs posted. 
  
  On the other hand, the lane currently mapped going north from Euclid Place https://www.openstreetmap.org/way/22795619 looks to be more of a driveway than anything else... and then to south, I'm guessing another private way connecting to the back lane of Queen. Could really benefit from walking by!
