Hello,

The official speed limit here is 30 km/h.  Your changeset has been reverted.

Please check this picture, which was taken this Thursday: https://www.mapillary.com/app/?pKey=1123343455742104

There is no C43 road sign to mention a 50 km/h speed, therefore the defaultt 30 km/h speed limit of the Brussels-Capital Region applies. (https://www.code-de-la-route.be/fr/reglementation/1975120109~hra8v386pu#pcwb5s3qpd or https://www.wegcode.be/nl/regelgeving/1975120109~hra8v386pu#qnofdw3izy)
