Thoroughfare is a common word, but as Andrew Denny says it is an odd word. It is made up from Old English and Middle English
From Wikipedia, the free encyclopedia
A thoroughfare is a place of transportation intended to connect one location to another. Highways, roads, and trails are examples of thoroughfares used by a variety of general traffic. On land a thoroughfare may refer to anything from a rough trail to multi-lane highway with grade separated junctions; on water a thoroughfare may refer to a strait, channel or waterway. The term may also refer to the legal right to use a particular way as distinct from the way itself.
1. A main road or public highway.
2. a. A place of passage from one location to another.
b. Right to such passage.
3. A heavily travelled passage, such as a waterway, strait, or channel.
Middle English thurghfare : thurgh, thorow, through; see thorough + fare, road (from Old English faru, fær, from faran, to go; see fare).]
