- So far as is known, the Wall Township location is still just in permitting, not active construction. You can find the exact location on the map at the Supercharge.info site I link below or in the opening post of the relevant thread here on TMC: Supercharger - Farmingdale/Wall Township, NJ
- Tesla's website map is not an accurate source for exact locations of future superchargers. The grey pins are placed wherever Google Maps places a pin for the general jurisdiction the supercharger will likely go in. So, in this case, Tom's River. If you ask google for directions from somewhere to "Tom's River, NJ", you'll see that the ending location pin is in the exact same spot. This has no bearing on where the actual future location will be except that it tells you the supercharger will likely be in Tom's River or the general surrounding area. Tesla isn't even always too particular about putting the pins on the actual jurisdiction, as evidenced by the fact that this location isn't even technically in Tom's River or Tom's River Township but rather the borough of South Tom's River. However, once the location goes live, Tesla will update their map with a red pin on the exact address/location. And it will be the one from the opening post of this thread.
If you want to follow supercharger development progress (i.e. known permits and construction starts) with actual locations, you should use the map at
supercharge.info. Or follow along in the appropriate thread here on TMC. You can pretty much ignore Tesla's map of future locations except to get a general idea of where they plan to build.
