Means to follow bombed thoroughfare (7)
I believe the answer is:
highway
'thoroughfare' is the definition.
(thesaurus)
'means to follow bombed' is the wordplay.
'means' becomes 'way' (a way or means of doing something).
'to follow' means one lot of letters go next to another (some letters go after or follow others).
'bombed' becomes 'high' (both can mean intoxicated).
'way' after 'high' is 'HIGHWAY'.
(Other definitions for highway that I've seen before include "Main road" , "Road-user's Code" , "Public road" , "Major route" , "Such robberies" .)
