Way to factory for maintenance (9)
I believe the answer is:
roadworks
'maintenance' is the definition.
I know nothing about this answer so I can't judge whether this works.
'way to factory' is the wordplay.
'way' becomes 'road' (road is a kind of way).
'to factory' becomes 'works' (eg a steel works).
'road'+'works'='ROADWORKS'
'for' acts as a link.
Can you help me to learn more?
(Other definitions for roadworks that I've seen before include "Street repairs" , "holding up travellers" , "reason for traffic hold-up" , "What delay motorists" , "They hold traveller up" .)
