Hi
you appear to have taken some of the public transport tags off the Adelaide Metro train station and added a saddler?

Should the intention be to add a new node exactly where the saddler shop is and leave the train station tag alone?

Hi
from Bing and Maxar satellite imagery....
Reggie Drive and Wynne Road do not appear to be living streets. Living streets need to be signed as such to be tagged this way

In view of description and website I changed to clinic. If you think otherwise feel free to edit.

healthcare=clinic

Hi
This looks more suitable as a specialist clinic. Do you admit inpatients?

Hi
from imagery and Mapillary it seems the speed limits were based on old information while the highway was being upgraded. Maxar imagery shows this an complete now so have changed all the speed limits through this area to 110kph

By the way, you are a very neat and accurate mapper. Well done.

I changed it to a simple polygon.

fixed now, tks

Thanks, it can be a big task.

The small line is selected/highlighted here
way/1055539309#map=19/-32.07076/115.93667

Hi
Yalgan Pass Park has it’s boundary drawn with two separate lines instead of one line. The iD editor has created a relation. The relation is unnecessary for this simple park boundary which could be drawn with one continuous line.
If you join or combine the two lines the relation is unnecessary and the tags can be added to the single line making the boundary. If you can’t work out how to do that then redrawing the boundary afresh and deleting the old lines will work.

You will see the small separate line close to the junction of Cadoux Promenade and Figtree Drive

Hi
If you zoom in closer to the roundabout you will see that the two segments that join the roundabout still have the wrong name

Hi
I added office=company and shop=trade
All things added to osm need a primary tag such as these to define what it is you are adding to the database/map

Highway speeds are sometimes reduced near particular intersections and from my experience it is often due to higher use by rural transport, like cattle trucks, winery trucks, forestry logging trucks, etc that take longer to get up speed compared to the usual highway goods transport trucks.
Are you able to verify the speed limits in person?

Hi
There is still a section of this road north of the Woolmers Rd turnoff that is marked 80km. Could the limit be lower here because of the intersection.

I think the tag natural=wood may be more suitable for areas of trees than tree_row

You could tag such crossings as unmarked if you feel uncomfortable with the safety of such crossings.
highway=crossing

Hi
the treed areas bear little resemblance to the real situation with only some patches of trees being mapped.

Hi
it is normal practice to continue footways across the roadways so that pedestrian routing can work. Should I revert your changes or are you able to fix?
