Hi WoboX and welcome to the Waze editing addiction!
It appears that the Belgium-specific forum is not too active, so you will probably get more help if you re-post this in the “Update Request” sub-forum with a post subject such as “Unlock request: Belgium”
Also, if you haven’t already done so, I encourage you to read up on the Map Editing manual for tips, tricks, and best practices.

Too bad he did not put a decent roundabout in there, and corrected the way the Krekelenberg is connected (not to the roundabout).
I unlocked all locked segments I could find. If needed, I can delete the ‘roundabout’ so you can put a new one in (note that I cannot create a new roundabout outside NL).
