Go round fish in road (8)

Ross

I believe the answer is:

turnpike

'road' is the definition.
(turnpike is a kind of road)

'go round fish' is the wordplay.
'go round' becomes 'turn' (both can mean to rotate).
'fish' becomes 'pike' (pike is a kind of fish).
'turn'+'pike'='TURNPIKE'

'in' is the link.

(Other definitions for turnpike that I've seen before include "Toll gate" , "Old toll-gate, or new road with toll stations" , "American highway" , "Toll gate/road" , "Old barrier" .)
