Parkway fee (4)
I believe the answer is:
toll
'parkway fee' is the definition.
(I've seen this in another clue)
This is all the clue.
(Other definitions for toll that I've seen before include "Be inclined" , "Charge to use, eg, bridge" , "Peal, chime" , "Charge for using, eg, road" , "Fee paid for use of a public road" .)
