This is the map I received from Mobility departement.
Green=20. Red=30. Black=50

Thanks for letting me know. I'll check with my collegues if the roadsigns are placed yet.

I have a side question: ALL the roads except for the ones I changed to 20 are maximumspeed 30 since last week. 3 roads stay 50.
Is there a way to change this in bulk or do I have to do this manually, street by street?

Heb de vraag doorgegeven aan mijn collega's van mobiliteit/handhaving en zij zullen dit vandaag nog nakijken.
