The Great Renumbering
The Great Renumbering: California State Highways Before 1965

Old State Shield California Signed State Routes 

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.

Pre-1964 HistoryWhen following links in the table below, note that the link will take you the page for the Post-1964 version of the route. Use the page menu, and look for the sections titled "Pre 1964 Signage History" (which have the graphic shown to the left) for information on the route prior to the 1964 renumbering. If the route changed numbers in 1964, this section will be talking first about the pre-1964 signed route number that corresponded to the post-1964 number of that page. Read a bit further down looking for the white bear-shield graphic. That signals the start of the discussion of the route that had the indicated number before the "Great Renumbering".
