Remaining on smart section of motorway? (7)
I believe the answer is:
flyover
'section of motorway?' is the definition.
The definition and answer can be both man-made objects as well as being singular nouns.
Perhaps there's a link between them I don't understand?
'remaining on smart' is the wordplay.
'remaining' becomes 'over' (as in 'we ate them all but had one over').
'on' means one lot of letters go next to another.
'smart' becomes 'fly' (fly can informally mean smart or well-dressed).
'over' put after 'fly' is 'FLYOVER'.
Can you help me to learn more?
(Other definitions for flyover that I've seen before include "Raised road" , "Road bridging another" , "part of highway?" , "Road or rail bridge" , "The High Road" .)
