west circular is in northern ireland

[factor-fiction]

Maybe they meant Londonderry (he said ,clutching at straws).
Yes, Ive only heard of North and South circular roads in London. Is the answer all one word? If not, do yoy know the letter split?

Is there a West Causeway- that would fit i think?
Do you have any more letters?

^ Petticoat Lane doesn't fit the letters, though.

[atrollope]

Petticoat Lane is a good answer

It is a good answer if we have been working off the wrong number of letters
