County roads

Addressing in Yolo County is based on a system of numbered county roads. The numbering system works in the following way:

1. North–South roads have numbers from 41 to 117 and increase from west to east.
2. East–West roads have numbers from 1 to 38A, and then from 151 to 161, and increase from north to south.

Each integer road number is generally one mile (1.6 km) apart, with letters occasionally designating roads less than one mile (1.6 km) apart. County roads entering urban areas generally become named roads once they cross a city boundary. Some examples include County Road 101 in Woodland being renamed Pioneer Ave. and County Road 102 (also known as County Route E8) in Davis being named Pole Line Road.
