Approach a location (6)
I believe the answer is:
avenue
'approach' is the definition.
(both can refer to a road)
'a location' is the wordplay.
I cannot really see how this works, but
'a' is present in the answer.
'location' could be 'venue' (venue is a kind of location) and 'venue' is found within the answer.
No letters remain.
This may be the basis of the clue (or it may be nonsense).
(Other definitions for avenue that I've seen before include "Wide (tree-lined) street" , "Wide, straight road" , "Thoroughfare, boulevard" , "Means of approach" , "Entrance passage" .)
