Please note that we map turn lanes as own ways only if they are structurally separated. That is not the case here. Instead the lanes tagging scheme is used, see https://wiki.openstreetmap.org/wiki/Key:lanes. Also you do not need to add "oneway=no" to roads because that is the default.
I therefore reverted the changeset with https://www.openstreetmap.org/changeset/149257804.
