It looks like the point for CR339 needs to move a little west. The point where we have it now seems to be a closed old intersection.
Yes, they moved the intersection off of the curve.

At that time, they hadn't even started the reroute. But Google Maps has current sat imagery that shows the new route open to traffic and the old route gone (no StreetView of the change).
Thankfully, label not in-use currently, so can easily move it to the new intersection, and put a 'closed' point in the place of the original one.
