All of this was updated. These should now be complete.

A few comments here:

1. Is GA 17 actually concurrent with GA 21 ALT?  I am not sure that this is correct unless I am seeing something incorrectly.

2.  On GA21Alt, JimDelPkwy should be GA17 or GA17_S depending on how number 1 is handled.

3.  On GA 307, JimDelCon should be GA21Alt_N or GA21Alt/17 depending on how number 1 is handled.

I shortened GA 17 to the Sonny Dixon interchange. I think I had misinterpreted one of the comments upthread. Also relabeled the points mentioned to reflect the proper route names.

GA 17:  GA21Alt_N>-GA21Alt

The rest looks fine and makes much more sense to me now.

This should complete this topic.

I guess GA21 is sort of correct, but I still think that it should be GA21Alt.

Mental typo. Fixed in https://github.com/TravelMapping/HighwayData/pull/5648
