Why have these roads been changed to 10 mph? Did you mean 20?

I would suggest that this road is not an expressway. Despite the three grade separated junctions, there is access for pedestrians & cyclists, the speed limit is low and there are still numerous side roads within this section.

Again, just because these ramps *are* the A516, that doesn't mean they *have* to be highway=trunk. The wiki page for highway=trunk_link even says "Use highway=trunk_link for link roads (sliproads and ramps) leading to and from a highway=trunk." As I have seen many times before, the sign colour could be incorrect. For example, there's a green sign here (https://www.mapillary.com/app/?focus=photo&lat=52.9124875&lng=-1.5158363888889&z=17&pKey=211770674253287&x=0.4926006856509276&y=0.5588215907497979&zoom=0) and yet this section of road is marked as a non-primary route (in OSM, highway=primary). So is it marked wrong, or is the sign wrong? Many signs before 1994 - and indeed newer copies - use an outdated colour coding system, and it looks as though this is the case with the roundabout direction signs on the A516 having left the A38. The signs on the off-ramp should be black and white. There are quite a few multiplexes like this, another example being the A50 and A515 to the west of here. All the A515 ramps to/from the A50 at Ashbourne are marked highway=trunk_link. As you say, the ramps at Mickleover should also be marked as highway=trunk_link, but this is a grey area as there is no defined start/finish point of the ramps after they have left the A38, as the A516 is a dual carriageway here. So I would leave the road tagged as highway=trunk throughout in this case. Same for the M26/M20 junction for instance. Unless there is a specified reason, these should be highway=trunk_link. The wiki says so, convention says so. The ref is irrelevant.

That is irrelevant. These are highway on/off ramps to the roundabout from the A38 - hence the change to a "link" highway. They can still carry the tag ref=A516.

Sorry why the revert? I did not change the ref from A516.

For the first two, the paths are continuous. There's no dead end for the public footpath/bridleway. They both go from a service road to a dedicated path. The fixmes didn't mention signage. For the latter, there is no visible trail on the imagery. If you think anything there is wrong then re-add the fixme tags.

It appears from the imagery that the paths are already connected and there are no stubs, so that's why I removed these fixme tags

You don't need to be arrogant. I shall add them back, but if I am told otherwise again then I shall mention this short exchange.

If you come to some sort of conclusion I will go over the area and add the missing tags, if required.

Then you need to speak to the StreetComplete team who's edits only add maxspeed:type tags for national speed limit roads in the UK. I'm confused what to do now. They say only one tag, now you say both. Who's right?

See the short discussion linked on the talk page. So long as the "maxspeed:type=GB:nsl_single" is there it should be fine.

Apologies. I only removed those as StreetComplete automatically has resurvey quests for construction areas

That tag signifies that a kerb of some type is there. Surveying on StreetComplete can provide the exact type on the ground (lowered, flush etc.)

Best to update to what is recommended by the editor with these branded shops.

I tested it myself and that is how they were removed. Re-added.

My apologies, but it seems the tag was removed automatically when I updated the platforms from 'train platforms' to 'tram platforms'

Is Portland Street pedestrianised now?

That's better. Just in my experience, road signs can be wrong or designed to not include certain road numbers. e.g. a sign may say 'M61' when it was meant to say '(M61)'

Do you have any other reference than "signs"? Signs can be wrong or sign the obvious route while ignoring the true road number

Hi, I believe it might be more appropriate to use 'kerb=lowered' ('Kerb ramp' on StreetComplete) for these, as 'kerb=flush' is more for kerbs where the pavement-road transition is almost completely level (according to the wiki), for example, crossings on speed tables where the road raises up to the kerb height.
