About: List of county routes in Ulster County, New York

County routes in Ulster County, New York, are mostly signed with the Manual on Uniform Traffic Control Devices-standard yellow-on-blue pentagon route marker, however, several routes are still marked with very faded, sometimes illegible blue diamond shaped markers with white or yellow lettering, and the route number inside of an outline of the county, similar to those old markers in Orange County. All roads maintained by Ulster County are assigned a county highway (CH) number; this number is posted on small green signs placed below the route marker but is otherwise unsigned. Each county route comprises one or more county highways; however, not all county highways are part of a signed county route.
