Chronology of California Highways

Phase VI: A Final Spurt, and then Reality Hits (1970-present)

1970

In 1970, the California Environmental Quality Act was passed. This added an environmental planning function to the design, construction, and maintenance efforts. Also in 1970 the Office of Transportation Planning and Research was created.

1972

In 1972, AB 69 was passed, which reorganized the Department of Public Works and the Department of Aeronautics into a new Department of Transporatation (Caltrans), with six functional and modal divisions: Highways, Mass Transportation, Aeronautics, Transportation Planning, Legal, and Administrative Services. The legislation also required Caltrans to prepare a California Transportation Plan, based on input from regional planning agencies and overall state objectives. Between 1975 and 1977, three draft plans were prepared and rejected by the public and/or the legislature. This was a significant shift, as the focus now moved from just highways to multiple modes of transportation, and from a central planning agency to regional agencies.

1975

The 1975 Draft Caltrans Transporation Plan was published. This Plan laid out the premises and objectives underlying future state transportation policy and planning and presented legislators with the choice of four future transportation policy directions. In particular, it enumerated some fundamental premises that reshaped the highway system:

Land use and transportation decisions must be more closely tied together.
An increase in population will put greater demands on transportation
Additional funding is vital because funding levels for State and local roads are not sufficient to preserve the public’s investment
The funding sources and allocation process should be brought in line with today’s needs and priorities.
The Streets and Highways Code should be revised to minimize allocation inequities among counties and between counties and their cities.
The state should eliminate north-south split and county and transportation district minimums, and substitute a control formula under the California Transportation Plan for county groupings (similar in principle to the district minimums).
The public transportation needs of non-auto users are acute and require immediate state attention and financial assistance.
Peak period congestion on urban highways, roads, and streets and major airports will continue to worsen regardless of the emphasis placed on other modes of travel.
Transportation facilities should be planned to minimize consumption of prime agricultural land and facilitate the movement of agricultural products.
Air quality in California will be dramatically improved in the next 20 years primarily due to emission control standards for automobiles.
If transportation energy consumption were to be substantially reduced within the next five years, the most effective action would be in the area of implementing strong disincentives to auto travel.

It was also about this time that drastic reductions in the buying power of highway revenues (due to inflation, increasing vehicle fuel efficiency, and legislative reluctance to increase taxes), escalating highway construction costs, and increased opposition to new highway construction by local politicians, activists, residents, and environmental groups led the state to began to eliminate controversial segments of the freeway plan. By the late 1970s, any remaining pretense that the remaining routes could be built was abandoned.

CA 65	LRN 249		CA 65	Redefine	Split segment (b) and delete a portion: "(b) Route 198 near Exeter to Route 104 on a route along the easterly side of the San Joaquín Valley, which route may include all or portions of any existing state highway route.

1977

In 1977, the California Transportation Plan Task Force released a report (Recommended Statewide Transportation Goals, Policies and Objectives) that presented a series of themes to guide state transportation policy. These themes were that:

Basic transportation service should be available to all Californians.
Planners should emphasize better use of existing transportation resources rather than concentrating on additions to current capacity.
Planners should consider social, environmental, and economic effects during planning and project selection.
Planners should rely on market incentives and competition as opposed to regulation to protect the environment, conserve natural resources, and reduce transportation costs. Regulation should be a tool of last resort.
The use of user charges was strongly recommended as the principal element of the transportation finance system due to reasons of efficiency and equity.
The need for flexibility in terms of project selection and significant public participation in the planning and decision making process was emphasized.

1977 Route	LRN	Former Signage	Present Route (R) and Signage (S)	Action	Segment
CA 91	LRN 175 LRN 43	US 91	CA 91	Redefine	Change "Route 15" to "Route 194". (Chapter 919)

1978

In 1978, the Legislature created the State Transportation Commission, assigning it fiscal control of the planning functions of the California Highway Commission and State Transportation Board. A budging process was adopted requiring a five year State Transportation Improvement Program (STIP) with input from local and regional government entities. This program was to be updated biennially.

The following changes were made to routes in 1978:

1978 Route	LRN	Former Signage	Present Route (R) and Signage (S)	Action	Segment
CA 39	LRN 171 LRN 62 LRN 2	CA 39	CA 39	Redefine	Divide into three segments: (a) Route 1 near Huntington Beach to Route 72 in La Habra via Beach Boulevard.

1981

1981 saw a 2¢ increase in the gas tax. Even with this, California now ranked last in the states in per capita spending on highways. Further, the increase in the tax came with a provision that decreed that the agency shift its priorities to system maintenance and reconstruction and away from the construction of new facilities. The bill, SB 215, established the following priorities:

Maintenance, rehabilitation, and reconstructing of the existing highway system for the purpose of protecting the public’s investment in the system.
Safety improvements for the purpose of reducing the number and severity of traffic accidents.
Operational improvements to the existing system for maximum service efficiency.
New construction.
Other purposes, including landscaping planting, litter pickup, and compatibility improvements.
