Old State Shield California Signed State Routes Old State Shield

California state routes were first signed in 1934. The signed route numbers were not the same as the numbers used in the legislative definition of the routes (LRNs), and not all LRNs were signed. The general algorithm for assigning numbers was as follows:

These rules applied to the initial assignment of numbers, and where possible, to other assignment of numbers as the space was filled in. As time went on, numbers were just assigned sequentially, so it is difficult to see the pattern in present-day routes. On July 1, 1964, all state routes were renumbered to account for the assignment of numbers to Interstates, as well as to make their legislative numbers adjusted to agree with their signed numbers.

Note: A specification sheet for the pre-1964 signage was posted to the AAroads forum. See this post by Quillz on 7/16/2016.
