If you have a GPS map, any brand other than Go-Cruise (Aldi), then please check the following for Bowral, NSW.

Does Shepherd St connect to Old South Rd?
Does McDonald St connect Bowral St to Merrigang St?
Does Albert St connect Bowral St to Merrigang St?
Does Ivy St connect Shepherd St to Merrigang St?
Does Gibraltar Rd connect Merrigang St to Duke St?

The correct answer is no, no, no, no, no.
Go-Cruise GPS says yes, yes, yes, yes, yes.

I need to know how global the error is in order to know who can fix it. What does your GPS say?

I already know that Wingecarribee Council maps are the source of the error. Some over-zealous employee more than 20 years ago marked proposed roads as if they actually existed. There are no plans to build these proposed roads, sometimes the routes aren’t even possible any more, Ivy and Albert Streets have houses built across the road line. Google Earth/Maps has it close to correct (the gaps are there but sometimes they’re the wrong length).

On Google Maps:

No
No
No
No
No

Reads the end of the OP.

Oh, you already knew that.

Sometimes the Council maps show what’s been gazetted as road or road reserve, but that doesn’t mean that everything on those maps has actually been constructed yet.

It’s so you can see what’s set aside as road, for future planning.

this is common – see “paper roads”. Some last for decades on maps. Another issue is when a cartography service will draw in a road / track from aerial imagery without groundtruthing. There’s tracks on old forestry topos which we found don’t exist probably because of this error.

The 2012 NAVTEQ maps in my Garmin Navigator show the streets in grey (the others around them are white).
