One of our club members, thanks Ray, discovered the location of the "Coming Soon" Supercharger Station for Coral Gables as listed on Tesla's Find Us map. Technically it's in Miami about 1.5 miles from Coral Gables. It's located at a Wawa convenience store and gas station at 6971 SW 24th St, Miami, FL 33155.
Here's a vicinity map. You'll notice that its not too far from the Tesla Coral Gables Service Center and the Miami - Dadeland Tesla Store.
For a full-sized image of the map, right click on it and open it in a new tab.
Here's a photo of the charging terminals under construction. There are a total of eight. They have a separate Coral Way entrance and exit from the rest of the store and they are located so as to minimize any chance of unintentional Icing.
We haven't yet been able to locate the permit to get a better idea of whether or not this will be a version 3 Supercharger installation.
Update as of October 23, 2019.
Above is the main switchgear.
This appears to be the location were Tesla would set its Supercharger Cabinets. Unless there is another concrete pad with more conduits, it looks like that there are only two Supercharger Cabinets for 8 charging terminals. If true, that would suggest that this is a version 3 Supercharger installation.
Update as of November 8, 2019.
This photo shows the utility transformer in green to the center right. I'm not sure if the green box to the left is also a utility transformer.
People living nearby are encouraged to visit the site occasionally, take high resolution photos of the construction progress, and forward them to me.
