Cortland County routes are not posted. However, the number is given on some intersection blade signs. Numbers below 150 occupy the western half of the County, those between 150 and 200 the eastern half, and a few higher-numberd roads are scattered. The numbers progress from north to south within each half.
County routes are generally composed of a single named road, and often letter suffixes are used for the different named segments of a continuous highway. Suffixes also denote small spurs off a main route. The latter usually extend for some distance, connecting primary highways in two or more Towns.
No county highway enters the City of Cortland, nor any Village in Cortland
County.
