Road prop two engineers replaced for all to see (6)
I believe the answer is:
street
'road' is the definition.
(I know that Street is a type of road)
'prop two engineers replaced for all to see' is the wordplay.
I cannot really see how this works, but
'engineers' could be 're' (Royal Engineers) and 're' is located in the answer.
The remaining letters 'stet' is a valid word which might be clued in a way I don't see.
This explanation may well be incorrect...
Can you help me to learn more?
(Other definitions for street that I've seen before include "lane" , "Thoroughfare lined with buildings" , "City thoroughfare" , "Road lined with houses" , "See 14" .)
