John Renshaw Drive is definitely the terminus. It's not part of the (defunct) National Highway network between Weakleys and JRD but for route numbering purposes it doesn't need to be a gazetted NH to be signed as a National Highway Route. Other examples include:
- former NHR8 and NHR31 into Melbourne (National Highway status terminated near the metro boundary)
- NHR94 in Perth from Midland to the Causeway
- NHR1 in Hobart along the southern part of Brooker Highway
The DMR in NSW didn't go with the more sensible 'consistent signage' option with NHR1 ending at Berowra - and not being signed between Swansea and Sandgate prior to the F3 being built - and NHR31 ending at The Cross Roads.
Weakleys Drive is the road that is strictly numberless and is mostly signed that way now.
