+X03 -> 9 (even though you can't change direction here, since there's a posted exit number, it should be a visible point)
I would make the IL 29 junction "9" and leave that shaping point alone.
I only suggested that, because there's a separate intersection between the interchange & IL-29.
Plus, you never know, hell might freeze over and they extend IL-6 to the north.
I'm betting Caterpillar would love that.
