Route diverted further from the centre (5)
I believe the answer is:
outer
'further from the centre' is the definition.
(I've seen this before)
'route diverted' is the wordplay.
'diverted' is an anagram indicator (each letter get diverted elsewhere).
'route' with letters rearranged gives 'OUTER'.
(Other definitions for outer that I've seen before include "External; part of archery target" , "External; peripheral" , "This space is beyond earth's atmosphere" , "On the periphery" , "Surrounding" .)
