logangee: I can see the gate in imagery, however, if you let USPS, UPS, and Amazon through this route, then the road is properly mapped.  If these delivery services are required to check in at the gate then perhaps a change could be made, however, I don't see any advantage to marking them as there is no reason for a router to route through this neighborhood unless going to the residences here in which once again it's correctly mapped as is.
You you wish to mark them as all private, you may do so, however this is a lot of work as you will need to mark all the driveways as private in order to ward off validation errors - all for little or no benefit to map users due to the nature of the roads in this area.
