Repaired the one at the end of the road (5)
I believe the answer is:
soled
'repaired' is the definition.
(soling is a kind of repairing)
'one at the end of the road' is the wordplay.
'one' becomes 'sole' (synonyms).
'at the end of' indicates one should take the final letters.
The final letter of 'road' is 'd'.
'sole'+'d'='SOLED'
'the' is the link.
(Other definitions for soled that I've seen before include "Pulled at one time" , "Repaired shoe" .)
