One of our club members has found the building permit for the "Coming Soon" Supercharger Station in Jacksonville which is planned to open later this year according to Tesla's Find Us map. It is located at 4866 Gate Parkway, Jacksonville. Google lists this location as a Wawa gas station.
Here is a vicinity map. You'll notice that it is about one half mile from the existing Tesla Store in Jacksonville. It is located across Gate Parkway from the Markets at Town Center which is the final expansion phase of the St. Johns Town Center.
We are not sure from the permit, but we believe this may be an 8-stall Supercharger Station.
