List of county routes in Monroe County, New York

In fact, the only field reference to a route's designation are reference markers posted at bridges and culverts along the highway, which carry the county route number on the second line.

Routes that do not cross either type of structure at some point are completely unsigned.

Several county routes were created, modified, or eliminated following a November 26, 2007, highway maintenance swap between Monroe County and the state of New York.

[1][2] All of the county route numbers assigned to the formerly county-owned sections of state routes were eliminated except for CR 236, assigned to a portion of NY 31 on Redman Road west of Brockport, and CR 99, assigned to the O'Rorke Bridge and Pattonwood Drive between the Rochester city line and CR 124.

[3][4] CR 236 was also one of several routes that gained mileage as part of the swap.
