I've heard that the site host agreement has been signed for a new Tesla Supercharging site in Brunswick, Georgia. This would be along the I-95 corridor, halfway through Georgia, and between Savannah GA and Jacksonville FL. I don't know which exit, and there are a few along that stretch, so it'll take some determined hunting to find it, even after construction starts. Therefore this does NOT yet qualify for a marker on the supercharge.info map, but we should be close to finding out where exactly.
Glynn County has their building permit system online. Their landing page for it implies that you can search for permits, but after I went through the registration process, I found that I could not actually search for existing permits, only see my own. Anyway, maybe someone else can figure it out:

In the meantime, start prowling Exits 29, 36 and 38!
