Link roads are rendered identically to normal roads

How to reproduce the issue?

1. (optional if you followed the above link) Draw two lines and choose a normal road and a link road preset for each of them respectively, i.e. one of the following combos:
   • highway=motorway and highway=motorway_link
   • highway=trunk and highway=trunk_link
   • highway=primary and highway=primary_link
   • highway=secondary and highway=secondary_link
   • highway=tertiary and highway=tertiary_link
2. Observe: You cannot distinguish between normal and link roads without selecting them and looking at the sidebar.

Screenshot(s) or anything else?

In openstreetmap-carto (standard style), you can easily tell highway=motorway from highway=motorway_link by their line width. In this case, the motorway links are incorrectly mapped as motorways except for the short segment in the upper part. Plus, you can guess incorrect layer=-1 tags for the motorway segments on the left because they’re rendered behind the secondary roads.

In iD, highway=motorway and highway=motorway_link look identical to each other (same width). This makes fixing these types of issues in the OSM road network error-prone, as you’ll likely miss a road segment while fixing the incorrect tagging!

In JOSM, the default MapPaint style doesn’t distinguish link roads from regular rendering either, but you can create or use a different style there which has the distinction – this is not possible to do in iD!

In the video, I’m changing some of the wrongly-tagged motorways to motorway links. Notice how the rendering doesn’t change when I do that, therefore I never know at a glance which road segments I already fixed and which ones are still wrong.

@tyrasd this doesn't cover *_link roads under construction or proposed ones, thus not matching how future paths get thinner.

Using the awesome new version of iD, I have now fixed the issue with the motorway links.

Plus, you can guess incorrect layer=-1 tags for the motorway segments on the left because they’re rendered behind the secondary roads.

Nope, that assumption of me was incorrect – the secondary roads had layer=1 while the motorway segments didn’t have layer tags at all.
