It depends on who is maintaining it, how it's maintained, how easy it is for a competitor to build a new road, and how involved the government is in keeping the status quo. I don't see a benefit to turnpikes in general, but it would depend on the specific road we're talking about. (and I don't know anything about 407) Keep in mind it's not really a "private" road (as in free market) if the government is granting specific companies permission to build and maintain the road. It's like talking about "private prisons" when no such thing exists.
