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The 1935 legislation also appears to have repealed a number of previously approved highways:

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 Generally, Chapter 29 established the new highway system and repealed all the Chapters that explicitly established old routings and the previous incarnations of the highway department.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.

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]".

LRN 16 Unknown   CA 175 Clarify Change "Hopland" to "[LRN 1]"

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.

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.


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 milage 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 Other 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
