Please do not add features to the map. that you are not sure about or are not officially approved. For highways in Poland you may refer e.g. to https://ssc.siskom.waw.pl/. BTW - there is no such value as "planned" for the "highway" key - you should use "proposed" instead, together with e.g. "proposed=trunk" tag (https://wiki.openstreetmap.org/wiki/Key:highway). I'm reverting your changeset.
