It was actually recently taken down, I'm local and heard the reason was something to do with it never actually having been properly permitted to be on the land it was on or something.
Edit: Zoning and not obtaining proper permission for it to be that tall were the reasons it was removed. https://www.wccbcharlotte.com/2026/02/14/judge-orders-removal-of-confederate-flag-along-i-85/
It's been really nice to drive through that area and not spend the next 30 minutes fuming and plotting to shoot gallium-filled paint balls at the aluminum pole it was on.
