New Moon Street (8)
I believe the answer is:
crescent
I believe this clue is a double definition.
'new moon' is the first definition.
(thesaurus)
'street' is the second definition.
(thesaurus)
(Other definitions for crescent that I've seen before include "Curved street or terrace" , "Phase of the moon" , "Young-moon shape" , "Waxing process could show one" , "Shape of new(ish) moon" .)
