There's one in Lincolnshire over a canal.Lots of river crossings were in control of the local land owner, or person who had the right to control the crossing. I’ve only seen them on the Thames, but I’m sure others exist. The order was often an act of parliament, much like canals, railways and turnpikes came into being.
I think many owners can extract a toll, though don’t.
Something like 15p to cross which is bugger all, hence why it was used on Customs surveillance courses as all the cool kids used plastic and got roundly berated by us old dinosaur instructors that sometimes cash was king.
