A thoroughfare is a public road that can get you from one place to another. When it snows, plows try to remove the snow from the thoroughfares so the school busses can take everyone to school. You’re welcome.
This somewhat old-fashioned word has a very common meaning — a public road that goes from point A to point B. The word is made up of thorough, Old English for basically, “through” and fare for “journey.” (Fare also now means a payment, but not in thoroughfare.) If a road is private, like a driveway, it’s not a thoroughfare. This word often appears in the phrase "no thoroughfare," which means there isn't a public route available.
