… repairing outer road (5)

Ross

I believe the answer is:

route

'road' is the definition.
(I know that road can be written as route)

'repairing outer' is the wordplay.
'repairing' is an anagram indicator (the order is repaired).
'outer' is an anagram of 'ROUTE'.

(Other definitions for route that I've seen before include "Send a particular way" , "Way, course" , "Direction taken" , "Course to be travelled" , "Direction of travel" .)

I've seen this clue in The Guardian.
