This is a part of OZZZI ONE transition routes of KATL, I found this at https://www.iflightplanner.com/Airports/KATL.
What does the number 6000 in red circle mean? I know in Jeppesen charts route arrows can bear mileage and altitude, but this 6000 number can’t be an altitude because at OZZZI fix expected altitude is 14000 or 12000.
