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.

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.

1989

In 1989, the passage of the Transportation Blueprint for the 21st Century (a collection of bonds and user tax increases) brought $18.5 billion in additional transportation resources to state and local transportation agencies over ten years. Its passage was driven by public concerns over growing traffic congestion and was given an added push by the Loma Prieta earthquake which severely damaged transportation infrastructure in the Bay Area. It included a proposal for the creation of an Interregional Road System to consist of 3,300 miles of the most important state freeway and highway routes. The $3 billion Interregional Road System plan was unveiled in 1990. The plan contemplated the eventual development to freeway or expressway standards of the 3,300-mile system, capacity addition on critical trunk-line routes, and modest design upgrades on an additional 1,800 miles of “priority routes” not formally part of the interregional system.

1990

1991

In 1991, and later in 1998, new federal surface transportation legislation introduced changes in the federal transportation program that have increased the challenges faced the state. This legislation shifted the balance of power between state and regional transportation agencies by granting the regional agencies a significant degree of financial and planning independence. It moved the state into a statewide coordinator of metropolitan area plans, overseer of rural and inter-city transportation concerns, and compiler of these various components into a single long-range (twenty-year) planning document.

1998

In 1998, SB 45 was passed. This bill introduced new changes in the structure of the state transportation program. The overall theme of the legislation was the need to increase local and regional flexibility over the use of transportation resources and greater local and regional control in project selection and design. It resulted in the development of a Transportation Strategic Plan. This plan included an in-depth discussion of issues related to state highways and brief discussions of issues related to intercity passenger rail, interregional highway system grade separations, and mass transit guideways.It expressed the following key principles:

California’s transportation process relies on open communication and an ongoing cooperative relationship between all members of the transportation community.
Caltrans has primary responsibility for the interregional mobility of people and goods. Regional and local agencies have primary responsibilities for regional and local mobility and for actions to manage commute and other congestion in their areas. Larger metropolitan areas are responsible for managing interregional commute congestion within the Transportation Management Area.
The rural areas of the state contribute to the state’s economic well-being and quality of life.
Connecting people and goods to growing urban centers, urbanized areas and major gateways is vital to the economy and quality of life in California.
Movement of goods and service into and through urbanized areas and gateways and to intermodal facilities is a critical component of the interregional program.
The designated interstate system is the backbone of the state’s transportation system for interregional, interstate and international goods movement, access to seaports, air cargo terminals and other intermodal transfer facilities. Improvements within major gateways in urbanized areas will often involve interstate routes.
Key segments of the state highway system are incomplete or underdeveloped. These will be developed to minimum facility standards as programming priorities allow, considering a range of qualitative and quantitative planning and operations factors.
Intercity rail is an important component of the state’s interregional transportation system.
