That I don't know unfortunately. I would think that just adding the ref should be the best solution, no?

Ah, it should have been name=Th 38, not ref=Th 38. I've fixed my mistake.

Hey!

As for ref=Th 38, I've simply used the ref of the continuation of the road to the west. The road there is using ref=Th 38.

As to moving int_ref=AH11 to the north: the routing of AH11 is along the northern way, and not the southern one. There are highway signs on the northern way, not the southern one.
