Well, it's about 50 miles longer than I would choose

. As long as the highway is running smoothly, it'll be about an hour BUT there are LOTS of trucks along that stretch at any hour of the day and it only takes one turning sideways to ruin your day. Kudos for starting well south of ATL...still one heck of a daily drive! Haven't been that way in quite a while but there has been periodic construction SOMEWHERE along that stretch since I moved to ATL almost thirty years ago!
Of course, it depends on
where in Macon you'll end up as to any additional drive-time. Good luck!
