A minor thoroughfare overseas (6)

I believe the answer is:

abroad

'overseas' is the definition.
(synonyms)

'a minor thoroughfare' is the wordplay.
'minor thoroughfare' becomes 'B road' (B road).
'a'+'broad'='ABROAD'

(Other definitions for abroad that I've seen before include "in France, say" , "on the Continent" , "Away in another country" , "Overseas; (of rumour) widely current" , "in Paris, perhaps" .)

I've seen this clue in The Times.
