Chronology of California Highways

Phase IV: Building the Freeway System (1947-1962)

1947

In 1947, in response to the recommendations of the Joint Interim Commission on Highways, Roads, Streets, and Bridges, the Legislature passed the Collier-Burns Act (Chapter 11). This act:

Added 67 mi of city streets to the state highway system.
Consolidated county road administration.
Required that the state maintain highways in cities. This was a significant shift for the previously rural-oriented Division of Highways.
Raised the gasoline and diesel fuel tax to 4.5 cents per gallon.
Increased automobile registration fees from $3 to $6, with a proportionate increase in the weight taxes on trucks.
Created a fund for all highway revenues and motor vehicle taxes.
Revised apportionment of revenues from fuel taxes to cities, counties, and the state.
Directed gasoline tax and registration fee revenues toward construction of freeways in urban areas and highways in rural areas of the state.
Divided state highway construction funds with 55% allocated to the southern half of the state, and 45% to the northern half of the state. This was a significant shift from the previous 49%/51% allocation. This also provided minimum funding for each county.
Indicated (Section 600) that highways added by the act (later changes added other highways to this list) would have limited expenditures until a number of identified deficients were corrected:

Gasoline fees were again increased in 1953, 1963, 1983, 1989, 1990, 1992, 1993, and 1994, to an ultimate tax of eighteen cents per gallon.

The 1947 Statutes (PDF, 173.8 MB) and 1st ex session statutes (PDF, 2.9 MB) made the following changes. Note that the California Legislature appears to have skipped from LRN 210 (route defined in 1939, number assigned in 1943) directly to LRN 221. The routes from LRN 221 to LRN 229 were added by 1st Ex Session Chapter 11. Later acts that year created LRN 212, and LRN 213. Additional backfilling of the skipped numbers was done in 1949 (LRN 214), 1959 (LRN 216), and 1961 (LRN 218).

1956

1956 saw the passage of the 1956 Federal Aid Highway Act, which created the 40,000 mi National System of Interstate and Defense Highways. The funding level for this undertaking was established at $25,000,000,000 over a thirteen year period, with increased funding for primary and secondary highways. The primary source was a 3¢ per gallon federal gasoline tax. Funds from this tax, along with funds from other federal highway user fees, were deposted into a "Highway Trust Fund". The federal share of Interstate construction costs was set at 90%, compared to the previous 50% rate.

The 1956 Statutes (PDF, 25.4 MB) made the following changes:

(Ex Sess Chapter 63)

1957

In 1957, the Division of Highways submitted a plan for a statewide freeway and expressway system to include city streets and county roads. In proposed the construction of 12,241 mi of controlled access highways serving every city with a population greater than 5,000. It would carry over half of the state's motor vehicle traffic. The state established for following criteria for route selection:

The system must connect the state's major centers of population.
The system must connect the state's primary centers of industrial activity and natural resources both with its centers of labor and materials and with its major shipping points.
The system must provide access to important military installations and defense activities.
The system must provide access to major recreational regions; national parks and monuments, and state beaches and parks; lakes; hunting and fishing areas; and to state institutions.
The system must connect as many seats of county government as is economically feasible.
The system must provide for continuity of travel into, through, and around urban areas from rural freeway approaches.
The system must provide for large traffic movements between population and industry centers within urban areas.
The system must provide the necessary capacity within the traffic corridor.
The system must connect with major highways of adjacent states.
The system must constitute an integrated system, with a minimum of stubs or spurs, to permit general traffic circulation.

1958

By 1958, freeway construction was proceeding apace. In Southern California, more than $700,690,000 had been spent on freeway construction, as illustrated by the map to the right. In 1957 and the first half of 1958, the division of highways opened a total of 53.8 miles of freeway in Southern California. There are some good articles here (page 1), here (page 2), and here (page 3). The 1958 Statutes (PDF, 27.2 MB) made the following changes:

LRN	First Signage	Other Signage	Present Route (R) and Signage (S)	Action	Segment
LRN 167	CA 15	CA 7	CA 47 I-710	Extend	Add the San Pedro-Terminal Island Bridge: "[LRN 165] in San Pedro to Huntington Drive via Long Beach, and including a bridge with at least four lanes from San Pedro at or near Boschke Slough to Terminal Island" (Chapter 74)

1959

In 1959, the Legislature approved the 1957 Highway Commission plan. It also made the 1953 gasoline tax increases permanent. Chapter 1062 was also passed, establishing the Freeway and Expressway system and defining a number of routes. However, Chapter 1062 noted:

It is the purpose of the legislature in extending lengths of routes presently in the State Highway System and in adding routes to the State Highway System in this act that additional mileage be incorporated into the State Highway System in order that said mileage may become a part of the California Freeway and Expressway System. There shall be no expenditures made on the extensions of state highways added by this act or on any state highways added by this act other than planning, design, maintenance, right-of-way acquisition and right-of-way clearance until the 1963-64 Fiscal Year.
