Drove by this one this evening. OSM is already showing it completed though it is not. GA 380 is in the process of being extended north of GA 16 to GA 83 northeast of Monticello.
GA 83 is now using the roundabout where GA 380 will meet it, though construction continues at the roundabout as well as on the extension. At least some layers of pavement were laid from what I could see from GA 83, though no striping has been done. I'd guess at least a couple months before it's opened.
