A route abroad (4)

I believe the answer is:

away

'abroad' is the definition.
(I've seen this before)

'a route' is the wordplay.
'route' becomes 'way' (way is a kind of route).
'a'+'way'='AWAY'

(Other definitions for away that I've seen before include "SECOND PART OF 18" , "(Of sports fixture) at opponents' ground" , "football result!" , "travelling" , "Not present, having left" .)

I've seen this clue in The Times.
