I didn't change Nabiac and Bulahdelah was built to motorway standards (the bit you're referring to isn't part of the bypass) – but as per that discussion I linked earlier it's been a long-standing practice to sign freeway-like dual carriageways in NSW as motorways for the good part of 18 years now and this change directly goes against it, but I'm okay waiting to see if this section ever gets upgraded to M1.

However, in the meantime, please keep Taree, Kew, Raymond Tce, Bulahdelah, and Karuah as-is as these are uncontroversially motorways.
