Reupload after failing to label it as [OC].
Expressways/motorways are high-speed roads where you can only enter and exit via ramps, with no intersections or traffic lights.
Dual carriageways (non-motorways) shown separately look similar but still have at-grade crossings and conflict points.
The definition is generally very fluid across the countries so please bear with me.
Construction data is shown for expressways only.

Picture 7 is beautiful! Seeing all the motorway of the world in one photo is amazing
You know, there’s that big dual carriageway when you get off the train? It mightn’t have been here when you were here last, Harry.
Now THAT is an interesting population map. 😀
