Highway travelled by horse noisily (4)

Ross

I believe the answer is:

road

'highway' is the definition.
(highway is a type of road)

'travelled by horse noisily' is the wordplay.
'travelled by horse' becomes 'rode'.
'noisily' indicates a 'sounds like' (homophone) clue.
'rode' is a homophone of 'ROAD'.

(Other definitions for road that I've seen before include "Street" , "See 10" , "motorway?" , "See 2" , "Abbey -, Beatles album" .)

I've seen this clue in The Everyman puzzle in The Observer.
