California "G" County Routes

A uniform numbering system has been adopted to uniquely identify county routes across the state of California. Within this system, each route designation has a letter and number combination. The first digit is a letter, and the second and third digits are numbers. The lower letters are generally to the north of the state, and the higher numbers are generally located in the southern part of the state. The lowest route is Lassen County Route A-1, and the highest route is Imperial County Route S-80.
