TURNPIKE. A public road paved with stones or other hard substance. 2. Turnpike roads are usually made by corporations to which a power to make them has been granted. The grant of such power passes not only an easement for the road itself, but also so much land as is connected with it; as, for instance, for a toll house and a cellar under it, and a well for the use of the family. 9 Pick. R. 109. A turnpike is a public highway, and a building erected before the turnpike was made, though upon a part out of the travelled path, if continued there is a nuisance. 16 Pick. R. 175. Vide Road; Street; Way.
