Here's another article by Haisten Willis about the upcoming extension of the Silver Comet Trail. The CSX deal makes the stretch from the trailhead at Mavell Road to Plant Atkinson Road straightforward. The tricky part will be getting it from there to the Chattahoochee, even though it's not that far away. CSX still has active track past Plant Atkinson, so the trail will have to follow some other path to cross the river.
But this is still fantastic.
