This section has different maxspeeds in each direction (rechecked April 2025). Your edit here is confusing (implying the same speed each way). Fixed at changeset/165880332

I'd move the tags for the interchange back onto way/1292847049. Highway=motorway_junction is for junctions (where ways connect), so doesn't belong on a node in the middle of the junction.

Confirming that maxspeed is correct here (checked on survey)

I've just updated Borenore Road (way/22797370) at changeset/163388218. Most of this is maxspeed 100, but northern and southern ends are maxspeed 80, and there's also a 50 zone through a residential section.

I've surveyed this junction again, and the traffic lights are only on Clarence Loop Road (the private crossing road has stop signs and gates, but no lights). I've updated this at changeset/163200029

These unsealed National Park roads were previously surveyed by me in 2015 - maxspeeds 40 and 20 (not 100). NSW Speed Data does have maxspeed=100, but type 'default' (which likely means that the actual maxspeed hasn't been entered in their system). Reverted at changeset/162268871

I've reverted this maxspeed change at changeset/162268705 - my survey in 2015 was maxspeed=20, Google imagery Nov 2024 still shows maxspeed=20. NSW Speed Data doesn't show any data for this road (not surprising as it's a driveway).

50 zone at my previous survey extended further to east (to eastern side of new motorway). Fixed at changeset/162268559

Maxspeed reverted at changeset/162265114. (Section east of roundabout also reverted - I must have seen a maxspeed on that section of road as I drove across the highway in order to update that maxspeed in June 2024)

I've removed the incorrect ref=B64 from Hobbys Yards Road at changeset/162265114 - I also split the northern end at a likely maxspeed change (maxspeed change indicated on NSW speed data, but I don't trust that source enough to add the maxspeed value for the new way). I've left the maxspeed on the main section alone. Other ways not checked.

Princes highway maxspeed reverted at changeset/162265114. I don't know maxspeed of McKoy Street, but I note it's in Victoria (so can't be from NSW Speed Data).

I'm thinking the first option, but I'll ask the Australian tagging list what they suggest.
