Hi there, to my understanding this is not an actual issue that needs addressing with the SES sign being physically located underneath the Syd Einfeld Drive elevated section here. Is that right or is there something that needs to get addressed still?

If the issue is that the sign isn't visible in the OSM tiles here, removing the "layer=1" tag on the bridge might solve it. Roads are always drawn over the top of closed paths as far as I'm away; the layer=1 tag might have been an attempt to not have it be drawn underneath the ground floor roads (which, again, it always will afaia).
