Toll gate (8)
I believe the answer is:
turnpike
'toll gate' is the definition.
(I've seen this before)
This is all the clue.
(Other definitions for turnpike that I've seen before include "Tollgate of the 16th-19th centuries" , "Toll road (hist.)" , "way in the US" , "Sort of road" , "where one pays one's way" .)
