I’ll use this thread to track changes to major highway classifications in Thailand. Many changes are correct, but new mappers sometimes overlook Thailand’s wiki guidelines, leading to potential conflicts. Occasionally, there’s vandalism as well—big thanks to @Nithinat_S for monitoring and reverting most when needed.
This thread can also be a great way to learn more about Thailand’s major highway classifications. If you review any changes, feel free to leave a note here or on the original changeset.
If you come across any unusual or questionable changes and want feedback, please share the link here.
