Likely one of the largest expressway systems that is unmapped, I've started to map out the Guangdong (CHN-GD) provincial freeways (about 1000km) now that most of national expressways (chng) in the province are mildly completed (which I'll go back to set new intersecting waypoints).
Chinese (https://zh.wikipedia.org/wiki/%E5%B9%BF%E4%B8%9C%E9%AB%98%E9%80%9F%E5%85%AC%E8%B7%AF) and English (https://en.wikipedia.org/wiki/Expressways_of_Guangdong) Wikipedia cover the expressways pretty well (though some of the parent pages are a few years dated), and all very well mapped on OSM. They are all tolled so entry points from toll plazas are clear.
For reference:

And we'd be adding:

There is a Draft PR with the .wpt routes I've completed: https://github.com/TravelMapping/HighwayData/pull/7535/files

System is in preview since 2024-07-21. 70 routes for almost 3,500 miles.
@nagamasa, how is the quality of that system? Should we review this earlier than chng?
