Created by the state Legislature in 1970 (California Government Code § 66500 et seq.), the Metropolitan Transportation Commission (MTC) is the transportation planning, coordinating and financing agency for the nine-county San Francisco Bay Area. Over the years, the agency's scope has grown, and it is now three agencies in one, functioning as MTC as well as the Bay Area Toll Authority (BATA) and the Service Authority for Freeways and Expressways (SAFE).

The Bay Conservation and Development Commission (BCDC) is dedicated to the protection and enhancement of San Francisco Bay and to the encouragement of the Bay's responsible use. When BCDC was established, only four miles of the Bay shoreline were open to public access. By drawing attention to the Bay, the Commission has played a major role in making the Bay and its shoreline a national recreational treasure. The Golden Gate National Recreational Area and numerous local, regional, and state parks and recreation areas have been established around the Bay since the Commission was established.

Caltrans manages more than 50,000 miles of California's highway and freeway lanes, provides inter-city rail services, permits more than 400 public-use airports and special-use hospital heliports, and works with local agencies. Caltrans carries out its mission of improving mobility across California with six primary programs: Aeronautics, Highway Transportation, Mass Transportation, Transportation Planning, Administration and the Equipment Service Center.

Bay Area Rapid Transit (BART) connects the San Francisco Peninsula with Berkeley, Oakland, Fremont, Walnut Creek, Dublin/Pleasanton and other cities in the East Bay. For more than 45 years BART has provided fast, reliable transportation to downtown offices, shopping centers, tourist attractions, entertainment venues, universities and other destinations for Bay Area residents and visitors alike.
