Bridge or road charge (4)
I believe the answer is:
toll
I believe this clue is a double definition.
'bridge' is the first definition.
(thesaurus)
'road charge' is the second definition.
(I've seen this before)
(Other definitions for toll that I've seen before include "Ring bell with slow strokes" , "Tax for using a service" , "Fee for road/bridge" , "Charge to use, eg, bridge" , "Form of road tax" .)
