Set up in the road the whole lot (7)
I believe the answer is:
install
'set up' is the definition.
(synonyms)
'in the road the whole lot' is the wordplay.
'the road' becomes 'st'.
'the whole lot' becomes 'all' (I've seen this in another clue).
'in'+'st'+'all'='INSTALL'
(Other definitions for install that I've seen before include "Fix in position ready for use" , "Settle" , "Station" , "Put in place ready for use" , "Emplace" .)
