Hello,

I surveyed it again this morning (Satuday, May 1).  The data in OSM is correct.

Something a little peculiar about the situation: the current situation has many supporters and opponents—to some extent about whether buses should drive on the pedestrian zone on the main boulevards—and its status as a test is uncertain.  We expect the current situation to stay unchanged for a few months, that’s why OSM includes both the new stop—you can see it on the photo—and the old one.  The old stop is still the official stop matching STIB/MIVB data and we cannot delete it while it still "exists" (there is a stop post, a platform and some information explaining the buses have been rerouted).

In the main map you would see the old stop in transparent colour and we marked it as non-usable (access=no).

I suggest we wait until the situation is clarified, there are chances the former situation will be restored.
