Pre 1964 Signage History Pre 1964 Signage History

Pre-1964 State Shield In 1934, Route 13 was signed along the route from Santa Cruz to Jct. US 101 at San Rafael, via San Jose, Mt. Eden, and Oakland. Multiple 1935 maps, however, show the route as Route 17, so the renumbering happened quickly after the original designation in 1934. This appears to be the route of present-day Route 17 and I-880.  Given the dates of the segments below, it is likely the Route 13 number was not reused until at least 1947, which was when LRN 227 was defined (the segment between Route 24 and former US 40, defined in 1935, was signed as Route 24).

Between I-580 and the current Route 61 routing (Doolittle Dr., LRN 226 and LRN 258), present-day Route 13 was unsigned prior to 1964, but was LRN 258 (added to the state highway system in 1959).

Between Warren Blvd and US 50 (now I-580) and Ashby Ave (Route 24, LRN 206), Broadway (unsigned, LRN 75), Route 13 was partially constructed as of 1963 (it was only constructed between Route 24 and Joaquin Miller Road). The routing of present Route 13 (then unsigned) was along Warren Blvd and then an upspecified routing to US 50 (LRN 5). This was LRN 227, added to the state highway system in 1947.

Construction for this freeway occurred mostly in the late 1950s. The Park Boulevard interchange was designed and designated as a future connection to the Shephard Canyon Freeday (then LRN 235, present-day unconstructed Route 77) through the Oakland Hills toward Moraga.

Between Route 24 and I-80 (former US 40), present-day Route 13 was LRN 206, but was signed as Route 24. This segment was added to the state highway system in 1935.

Between I-80 (former US 40) and present-day Route 61, the routing (unconstructed) was also LRN 206. This portion of LRN 206 was added to the state highway system in 1959.

Constructed as freeway from I-580 to Route 24. Route 61 was a planned freeway that paralleled I-80 near Berkeley.

Unconstructed Portion

Rte 13 / Rte 24 StubUnconstructed State Shield Unconstructed for 4 miles from Route 61 to Route 580. This section would have paralelled Hegenberger Road and 73rd Avenue. However, no local roads adequately fit the definition of a traversable highway. The 4.3 miles that were in the freeway and expressway system were deleted effective 1/1/1982.

Sean Tongson notes that a short stub of concrete at the on-ramp from northbound Route 13 to eastbound Route 24 seems to suggest a possible flyover/under ramp may have been planned from southbound Route 13 to eastbound Route 24.

Naming Naming

Earl WarrenRoute 13 from I-580 to Route 24 in Oakland (~ ALA 4.262 to ALA R9.421) is named the "Warren Freeway". Earl Warren (March 19, 1891 – July 9, 1974) was an American politician and jurist who served as the Governor of California from 1943 to 1953 and Chief Justice of the United States from 1953 to 1969. The "Warren Court" presided over a major shift in American constitutional jurisprudence, which has been recognized by many as a "Constitutional Revolution" of the liberal, with Warren writing the majority opinions in landmark cases such as Brown v. Board of Education (1954), Reynolds v. Sims (1964), Miranda v. Arizona (1966) and Loving v. Virginia (1967). Warren also led the Warren Commission, a presidential commission that investigated the 1963 assassination of President John F. Kennedy. He is the last Chief Justice to have served in an elected office before entering the Supreme Court, and is generally considered to be one of the most influential Supreme Court justices and political leaders in the history of the United States. Warren was born in 1891 in Los Angeles and was raised in Bakersfield, California. After graduating from the law program at the University of California, Berkeley, he began a legal career in Oakland. He was hired as a deputy district attorney for Alameda County in 1920 and was appointed district attorney in 1925. He emerged as a leader of the state Republican Party and won election as the Attorney General of California in 1938. In that position, he played a role in the forced removal and internment of over 100,000 Japanese Americans during World War II. In the 1942 California gubernatorial election, Warren defeated incumbent Democratic governor Culbert Olson. He would serve as Governor of California until 1953, presiding over a period of major growth for the state. Named by Assembly Concurrent Resolution 96, Chap. 166 in 1957.

The portion from Route 580 to Route 24 was submitted for inclusion in the interstate system in 1945; it was not accepted.

The designation I-13 was proposed in November 1957 for what is now I-605. This was rejected by AASHTO. The I-605 routing was later proposed as I-105, before the number I-605 was chosen.

Pre-1964 Legislative Route Pre-1964 Legislative Route

The route that would become LRN 13 was first defined in Chapter 111 of the 1901 statutes: "That portion of the Sonora and Mono wagon road, commencing E of Sonora and at a point commonly known as Long Barn in Tuolumne Cty and running thence across the summit of the Sierra Nevada mountains to Bridgeport in Mono County is hereby declared a state highway." This route was also referenced by Chapter 150 in the 1905 statutes. It was first funded in the 1909 First Bond Act as a route "From Salida to Sonora". In May 1919, Chapter 510 re-declared this routing to be a state highway, "All that portion of the public highway commencing at the end of the Sonora and Mono state highway at Long Barn in Tuolumne county and leading therefrom to the eastern boundary of the city of Sonora and known as the Sonora and Mono Road is hereby declared to be a state highway...". Thus, in 1935, the routing was codified into the highway code as:

From [LRN 4] at Salida to [LRN 23] at Long Barn

The portion from Salida to Sonora was considered a primary highway.

This route had the following pieces:
