The map was updated in September, just when the street became one-way.
The street is still used by routes towards Brussel Noord whereas outbound relations use Ch. Haecht/Haachtsestwg.  Stops were relocated too.

So, what you are describing in your note is exactly what is already on the map.

Open the Transport Layer and you will see there are bus routes in both streets, one in each direction.

I’ll close this note.
