Street, avenue (4)
I believe the answer is:
road
This clue is a double definition.
'street' is the first definition.
(I know that street can be written as road)
'avenue' is the second definition.
(I've seen this in another clue)
(Other definitions for road that I've seen before include "Way to achieving a particular outcome" , "Highway or byway" , "Way travelled by boat" , "Street" , "See 10" .)
