Urban thoroughfare (6)
I believe the answer is:
street
'urban thoroughfare' is the definition.
(I've seen this in another clue)
This is all the clue.
(Other definitions for street that I've seen before include "Way; setter (anag.)" , "Acceptability amongst the 'with it' young" , "Way < in which common man is" , "Town road" , "Tester (anag.)" .)
