Thank you for cleaning up the route relation.

But if you're riding along here you don't turn onto the pedestrian crossing then onto the road. The cycleway needs to join the intersection and meet in the middle node like the incoming roadways. It's like any other intersection where physically separate directions/ramps/slip lanes join, it's just that one of the ways doesn't have motor vehicle access.

Like the main roadway, there was both a highway=crossing node (where the pedestrian crossing and highway intersect) and a highway=traffic_signals node (where the stop line physically is, along the highway or cycleway).

The cycleway is separate from the footpath and separated from the roadway with a kerb and intermittent vegetation, just like the example on the wiki.

What was wrong here? The cycleway is mapped separately from the main carriageway so it had its own highway=traffic_signals node at the stop line for the intersection, like the other incoming ways. highway=traffic_signals#Traffic_signals_for_cyclists

I have surveyed and found nothing prohibiting bike traffic. In fact, there is a beg button at node/1788455750 explicitly provided for cyclists to activate the lights and continue south on the roadway on Tapleys Hill Rd. (I don't know if there's any established way to tag that)

Is cycling really prohibited along here? There is a parallel bikeway but doesn't appear to be anything obliging cyclists to use it (as there would be at the entrance to a freeway).

I'd agree it's not wise to cycle on an 80 km/h main road with no bike lanes but access tags are only about what is legal.

slice0, if you are referring to me as one of the SA community members you've discussed this with previously, you are misinterpreting my position. I welcomed your importing of DIT classification as a starting point for updating the map, but always maintained, as fortera_au has given in the second comment here, there could be reasons to vary from it.

Is there any consensus that classification needs to follow that source exactly?

Makes sense. I made the Kintore Ave-Pulteney St consistent with the KWS-Kintore Ave section for the time being.
