Chronology of California Highways

Phase III: A Significant System is Created (1933-1946)

1933

In 1933, the Legislature amended the State Highway Classification Act of 1927 with Chapter 767 of the 1933 Statutes (PDF, 173 MB), adding 6,700 mi of county roads to the State Highway System (all classified as secondary highways). Highway construction funds were allocated equally between primary and secondary highways. The legislative barrier that prevented state highway funds from being used in urban areas was removed. 1933 also saw the creation of an eleventh district, with headquarters in San Diego.

Note: It is difficult to relate the specific text in the 1933 act with the routings today. Text shown in light purple represents the closest equivalent to current routings, if it could be identified. For more specifics, please visit the appropriate page for the route or LRN in question (information for the LRN is always at the end of a given route's entry page).

1934

In 1934, the state began numbering non-Federal Highways with a "bear shield", shaped like a miner's spade and displaying a grizzly bear above the number. Signage was still done by the CSAA and ACSC.

1935

In 1935, Chapter 29 established the Streets & Highway Code.

The 1935 legislation also appears to have repealed a number of previously approved highways:

Trinity-Humboldt State Highway Approved March 26, 1903, Chapter 366. It appears to have been part of LRN 20 allocated in the Second Bond Act. The authorization for the survey was repealed by 1935 Chapter 29 Article XX
Bakersfield, Maricopa and Ventura Road Approved June 16, 1913, Chapter 610. Routing never fully constructed, although portions are in the state system. Repealed by 1935 Chapter 29 Article XX.
Emigrant Gap June 16, 1913, Chapter 619. This was a modification of the existing US 40 to eliminate a grade crossing. Repealed by 1935 Chapter 29 Article XX.
Yolo and Lake Highway Approved May 18, 1915, Chapter 283. Allocated as LRN 50 in the 1919 Third Bond Issue. 1915 Chapter repealed by 1935 Chapter 29 Article XX
Pasadena State Highway Created, June 9, 1915, Chapter 704. Allocated as LRN 61 in the 1919 Third Bond Issue. 1915 Chapter repealed in 1935 Chapter 29 Article XX
Bakersfield to Ojai, Kern-Ventura State Highway. Created June 12, 1915, Chapter 748. This routing (Ojai to Bakersfield) was never established as a state highway -- the funding was for a survey only. However, state highways do exist to cover the routing. Repealed by 1935 Chapter 29 Article XX
Pescadero-Redwood Park Road June 12, 1915, Chapter 764. Road never constructed. Repealed by 1935 Chapter 29 Article XX.
Middle Lake Highway Approved June 12, 1915, Chapter 765. Added as an extension to LRN 28, 1921. Chapter repealed by 1935 Chapter 29 Article XX
Vallejo to Sears Point Created, August 9, 1921, Chapter 841. This was later LRN 208, 1939.
Susanville to Nevada Approved June 1, 1917. Repealed by 1935 Chapter 29

Most of the repeals were of authorizations for surveys; the routing was were actually added into the system at some point. Generally, Chapter 29 established the new highway system and repealed all the Chapters that explicitly established old routings and the previous incarnations of the highway department.

The following new highways and changes were made in the 1935 legislation (PDF, 140 MB). Please see the pages for an individual route or LRN to see the specifics of how the route was established in 1935 and the changes thereafter.

Notes:

1936

The San Francisco–Oakland Bay Bridge opened to traffic. The bridge represented a remarkable engineering and political achievement.

1937

1937 saw the completion of the Golden Gate Bridge. Note that this bridge is not part of the state highway system; it was designed, constructed, maintained, and is still owned, by the Golden Gate Bridge, Highway, and Transportation District. The year also the completion of what became Route 1, also known as the Pacific Coast Highway. The route served /serves as an important tourist and commercial corridor. This is was California’s first complete north-south highway.

1939

In 1939, the "Freeway Law," sponsored by state senator Arthur H. Breed, Jr., is passed by the state legislature. This act allows the construction of highways along which adjacent property owners do not have rights of access, and gives the state broad powers of land acquisition for the construction of freeways. It also requires the state to reach an agreement with local governments before streets can be closed for the construction of a freeway. This clause gives cities and counties considerable leverage regarding freeway design and location.

Within two weeks of the passage of the Freeway Law, the California Highway Commission approved the first group of freeway declarations involving thirty-four miles of highways. Among these was the Arroyo Seco Parkway, for which construction started in 1936.

1939 also saw the completion of a Statewide Highway Planning survey. The focus was on the rural state highway system. It inventoried the system, and presented traffic data to justify the contention that much of the system was deficient in terms of meeting current traffic needs. It also reported that 47% of the system was still not surfaced, many roads were becoming worn out, and hundreds of bridges suffered from structural deficiencies.

The 1939 Statutes (PDF, 162.7 MB) made the following changes:

LRN	First Signage	Other Signage	Present Route (R) and Signage (S)	Action	Segment
LRN 4	US 99	US 6	I-5	Reroute	Delete segment (b) (although this was captured in the extension of [LRN 79]) (Chapter 473)
LRN 6	US 40		I-80	Clarify	Change "Woodland Junction" to "[LRN 7]". (Chapter 473)
LRN 16	Unknown		CA 175	Clarify	Change "Hopland" to "[LRN 1]" (Chapter 473)
LRN 38	Route 89	US 40		Route 89 I-80	Change "Meyer's Station" to "May's Junction" (Chapter 473)
LRN 65	CA 49		CA 49	Combine	Combine the first two segments into one, and added Diamond Springs as one of the "vias". (Chapter 473)
LRN 79	CA 126		CA 126	Extend	Extend east along the former [LRN 4] routing to terminate at "[LRN 23] via Castaic Junction and Saugus". (Chapter 473)
LRN 104	CA 116		CA 116	Clarify	Change terminus of (b) back to Shellville. (Chapter 473)
LRN 207	CA 30		CA 330	Number	Delete the 1937 definition, and recreate it as LRN 207, with the same routing. (Chapter 473)
LRN 208	CA 48		CA 37	Define	Define: "[LRN 8] near Sears Point to [LRN 7] near Lake Chabot." (Chapter 473)
LRN 209	CA 151		CA 151	Define	Define: “[LRN 3] near Station 398, according to the survey of said [LRN 3], Section B, to Shasta Summit near Summit City” Note: Route number assigned in 1943. (Chapter 794)
LRN 210	CA 139		CA 139	Define	Define: “[LRN 28] near Canby to the Oregon State Line near Merrill” to the state highway system, provided that the United States Government, through its agencies the Bureau of Public Roads and Forest Service construct or reconstruct [the highway] with highway funds or any other funds made available by congress for highway purposes within the state of California. No number was assigned.US 299 to the Oregon state line Note: Route number assigned in 1943. (Chapter 338)

Note: The California Legislature appears to have skipped from LRN 210 (route defined in 1939, number assigned in 1943) directly to LRN 221. Some route numbers were backfilled by later legislation (LRN 212 in 1947, LRN 213 in 1947, LRN 214 in 1949, LRN 216 in 1959 and LRN 218 in 1961), but not all numbers were used.

1940

On December 30, 1940, the first freeway in the Western United States opened—the Arroyo Seco Parkway, now the Pasadena Freeway, Route 110. This project marked the beginning of the freeway era in the Golden State.

1941

The Defense Highway Act of 1941 was passed by Congress. This gave the highest priority for highway construciton to the Defense Highway System as approved by the Secretary of War. Approximately $1,000,000 was approved for California Defense Higways. However, highway construction was limited to plant access roads, defense highways, and projects deemed essential to the defense effort.

The implementation of gasoline rationing in Demember 1941 resulted in a sharp decline in gasoline tax revenues (up to 50%).

A Rural Highway Needs survey was completed. This indicated that the state highway system was underfinanced, 65% of the mileage did not meet current design standards, and that projected traffic increases were expected to result in an additional 800 miles of roads being classified as inadequate by 1950. It estimated that it would take upwards of $443 million to bring the rural system to current standards.

The 1941 Statutes (PDF, 153.9 MB) made the following changes:

LRN	First Signage	Other Signage	Present Route (R) and Signage (S)	Action	Segment
LRN 166	US 101		(former) CA 245 I-5	Reroute	Change endpoints: "[LRN 172] at the intersection of Downey Road ~~Indiana and Third Streets, in Los Angeles,~~ to LRN 174 near Norwalk ~~[LRN 171] near Sante Fe Springs~~". (Chapter 142)
LRN 207	CA 30		CA 330	Truncate	Remove the northern branch of the route. (Chapter 142)

1943

In 1943, the legislature appropriated $12,000,000 for surveys and the preparation of plans and specifications, in anticipation of a post-war highway construction boom.

The 1943 Statutes (PDF, 173.1 MB) made the following changes:

LRN	First Signage	Present Route (R) and Signage (S)	Action	Segment
LRN 18	CA 140	CA 140	Truncate	Delete segment (b): "[LRN 40] to the Yosemite National Park Boundary at Crane Flat." (Chapter 964)
LRN 56	CA 1	CA 1	Other	Permit the commission and the department "to abandon and relocate any portion or portions of [LRN 56] as now established and laid out between the intersection of [LRN 56] and [LRN 55] south of San Francisco and the town of Farallon City in San Mateo County and to take any and all action necessary for such abandonment and relocation. Such abandonment may be effected prior to relocation and pending relocation the commission and the department may adopt and maintain any traversable road around the portion or portions so abandoned." (Chapter 661)
LRN 173	CA 26	I-10	Clarify	Change terminus: "… to ~~the intersection of Ninth and Indiana Streets in Los Angeles via Tenth Street~~ [LRN 166] near Downey Road". This terminus was former Route 245. (Chapter 964)
LRN 209	CA 151	CA 151	Number	Amend the 1939 definition to specify this as LRN 209. (Chapter 964)
LRN 210	CA 139	CA 139	Number	Repeal the 1939 definition and add the route, with the same routing, as LRN 210. (Chapter 964)

1944

In 1944, the California Highway Commission recommended a major post-war highway construction program of 145 individual projects, at an estimated cost of $80,000,000.

Also in 1944, Congress passed the the Federal Aid Highway Act of 1944.

The following is a good map of the routings in Los Angeles at this time:

1945

The following changes were made by the 1945 statutes (PDF, 146 MB):

LRN	First Signage	Other Signage	Present Route (R) and Signage (S)	Action	Segment
LRN 2	US 101		US 101	Change	Change northern end of segment (a) to be the Golden Gate Approach: “(a) The junction of [LRN 56] (Funston Approach) and the approach to the Golden Gate Bridge in the Presidio of San Francisco to the international...” (Chapter 1214)
LRN 62	CA 39		CA 39	Extend	Reunify segments (a) and (b) to create the original 1935 definition: [LRN 171] near Buena Park to [LRN 9] near Azuza (Chapter 1269)

Phase II: Early Growth (1915-1932) Phase IV: Building the Freeway System (1947-1962))
