There were a few occasions while at bootcamp last week when I was asking locals how to get to certain places and a few of them used what sounded like the word ‘rhewl’ as part of their directions. I can’t find anything like it in my dictionary, so I don’t know if it’s a regional description or something like that. Does anyone recognise it? I’m spelling it like I heard it, so have no idea if it’s correct. Diolch. 
Probably “yr heol”, meaning “the road” - which is often pronounced (and sometimes even written) as “yr hewl”.
rhewl is one of the many words for street/road. Its also the name of a village in Denbighshire.
ETA: As Kinetic said, it probably comes from yr heol originally.
Could it be a shortening of - ar draws/across
Diolch yn fawr iawn. That makes perfect sense!
