Attempted to ride the planned Silver Comet extension from Smyrna to the network of the Beltline trails. Even though a few gravel cyclists have successfully ridden this section, we found the old railroad bed to be extremely overgrown and impassible without a machete and a chainsaw. We bailed at Oakdale Rd and rode Atlanta Rd -- not as bad as one would think. The Tour of Atlanta was awesome Dec 2024 Update: The completed construction of the Silver Comet Extension that starts about a 1/4 mile east of the Mavell Rd Trailhead (right fork just before the Alpe d' Publix) to Plant Atkinson Rd. has eliminated the overgrown-with-kudzu section of the start of our ride in 2022. Therefore, this is totally ridable with a road bike. The Silver Comet extension from Plant Atkinson Rd to the bike path along Atlanta Rd is still under construction and is expected to be opened in early 2025. The big hang-up is the reconfiguration of the railroad trestle abutment to accommodate the bikepath on the west side of Atlanta Rd. With caution, this small section of the route can easily be circumnavigated.
