Every county-maintained road is assigned an unsigned county highway number for inventory purposes. The majority of county highways are part of signed county routes; however, some are not posted with any designation. Those highways or parts of highways that are not part of any county routes are listed below.
1. ^The eastern half of CR 2 frequently crosses the county line, and the sections that lie in Dutchess County are maintained by that county as part of CR 50.
