A thoroughfare is a primary passage or way as a transit route through regularly trafficked areas, whether by road on dry land or, by extension, via watercraft or aircraft. On land, a thoroughfare may refer to anything from a multi-lane highway with grade-separated junctions to a rough trail. Thoroughfares are used by a variety of traffic, such as cars, as well as pedestrians on roads and highways. On water, a thoroughfare may refer to a strait, channel, or waterway. The term may also refer to access to a route, distinct from the route itself. Thus, thoroughfare may refer to the legal right to use a particular way.
