Dragon: Based on chatter on a couple of sites it looks like The Dragon is likely cleaned up at this point. Several riders discussing their runs back and forth.
Cherohala: problem is on the Tennessee side. Advised that you can still enjoy most of the Skyway and ride "out and back" if you start at Robbinsville. There was also a detour mentioned on Rafter Rd but it was advised against due to it being a one lane country road with bad curves, switchbacks, and also in need of repair.
