Inclined walkway (4)
I believe the answer is:
ramp
'inclined walkway' is the definition.
(I've seen this in another clue)
This is all the clue.
(Other definitions for ramp that I've seen before include "Inclined walkway" , "It gets travellers off" , "Sloping walkway" , "Sloping platform" , "Sloping passage" .)
