`old_name=` has already been used. These are debatable as proper `name=` , as it may be "Former" / "前“. It's a descriptive title.

Please don't change to something incorrect to artificially influence rendering. `=monument` is for large structures the size of buildings.

"Tung Chung East" is a planning name. That's still a name.

This is not a `=*_link`
They are 2 branches. The opposite of a fork.

For in between junctions, closeby is TMR eastbound way/1264077323
Other troublesome cases: Airport Rd, Lion Rock Tunnel Rd, Waterloo Rd, Wan Po Rd
In terms of visualization to the degree of catering for the renderer, you can easily see this sections connects `=motorway` TMR only, unable to exit at Castle Peak Rd. And there will be restrictions.

Fundamentally, `highway=` is not designed to as precise as delineating the exact legal extent. It will already fail at merge/diverge at junctions. way/151834877

The guidelines are guidelines. It may not be very strict and rigorous. It was written by an interested human at spare time only. It won't cover all cases and situations in how it should be applied. It's already defective when Discovery Bay Tunnel is Tunnel Area, but is not, and should not be `=motorway` for many reasons.

This is being more detailed and targeted towards the functional and legal implications. Other map data would simply not respect the physically separated rule, drawing another line at Castle Peak Rd, making it seem more natural.
HK is further more complicated than other countries.
`motorway=` is documented motorway=*
It doesn't make sense to change `=motorway` and `=motorway_link` in between junctions for the exact extent. That's not legible and clean either.

(make stub extensions, and split them)

JOSM is easy, and doesn't have to be tedious. You only need to learn how to make stub extension placeholders, and use "Replace Membership" to transfer them into the targets. Then delete the inapplicables, and the stubs.

The exact extent is using `motorway=no`

Please don't use `type=site` + `building` , that's mixed up with `type=building` (but it still need a `building=` polygon as outline)
Please try to read how 3D Buildings are done before doing it. And start with something simpler.

And don't leave `building=` + `building:part=`

`type=site` has basically no software support, and you still left `shop=mall` on the members. It should be grouped together with Phase 3.

2. Please don't draw when there are only traffic cones either

Please don't draw a pair of lines when there's no raised separation, Cf `=turning_circle`

(Similar to not connecting `bridge=` directly)

Please don't merge and connect `=steps` with `=footway` in a right-angle. There should be an L-shape turning corner being either stairs or flat.

This one is a public bus-only road, not franchised only. It can be discussed.
