Way, or means (6)
I believe the answer is:
avenue
This clue is a double definition.
'way' is the first definition.
(avenue is a kind of way)
'means' is the second definition.
(I have seen 'Means of approach ' mean 'avenue' so perhaps 'means' could also mean 'avenue')
(Other definitions for avenue that I've seen before include "A line of approach" , "Tee-lined road" , "Road lined with trees" , "Wide, straight road" , "Thoroughfare, boulevard" .)
