A county highway (also county road or county route; usually abbreviated CH or CR) is a road in the United States and in the Canadian province of Ontario that is designated and/or maintained by the county highway department. Route numbering can be determined by each county alone, by mutual agreement among counties, or by a statewide pattern. In England and Wales, county road, as alluded to in section 29 et seq. of the Local Government Act 1929, was the term used to refer to any road for which a county council was the responsible highway authority.
