Hi,
Thanks for the heads up about that. I'm really not great with actually mapping out these route relations but I will definitely be more careful to avoid leaving any gaps next time! Been a while since I've edited OSM so apologies if there's been any other errors I've introduced in other change sets

All the best

There are a few other county roads tagged like this in your prior changesets:
