please follow the naming standards of the community. Do not mix Thai/English names in the name tag. Put Thai script in name and name:th, the English name in name:en. In case of brand names which use Latin script also in Thailand as their main description use that in the name tag.

You have changed the name tag to be mixed Thai/English in this changeset. This is not the usual way we do in Thailand. Please check the wiki on bilingual name tags. name is supposed to be in Thai script. English names are in name:en for map makers to decide whether to include it in their individual map design.

It is a wrong spelling on their sign. I put in both spellings and removed the riverbank.

regarding mini hydro: I think the main reservoir is a bit upstream. It it a pump storage plant? so maybe the empty reservoir is the lower basin?

A major change like this could have deserved a changeset description. Especially when it is done by a user who did not edit anything before.

Based on the physical road characteristics as visible from aerial imagery and the road also being part of the AH network the upgrade itself seems reasonable.

Did you notice that you have missed dozens of secondary_link ways when changing the classification?
