The "both" center lines are one osm way:

I broke up the way and it should look nicer soon.

However this might be a Mapnik error - you can try report it.

Looks like a Mapnik error to me too. I don't think there's anything we can do to fix this on our side.

[kocio-pl]

Could you report this error to Mapnik then? This software is used by big companies and the chances are that such glitches would be fixed.

I have found another place where this is visible and might be useful for testing:

It was in fact an issue on our side. Fixed by #3202.
