Public transportation 
Mass transit 
The Bay Area is served by a number of mass transit systems:
- Bay Area Rapid Transit (BART) - A subway/commuter rail service that serves parts of the Bay Area, including San Francisco, Oakland, Berkeley, Fremont, and Walnut Creek. It has a direct connection to San Francisco International Airport while a direct connection to Oakland International Airport is currently under construction.
- Caltrain - A commuter rail service that connects San Jose and cities along the Peninsula with San Francisco, and with the BART system by way of the Millbrae Station.
- Amtrak - There are several Amtrak stations throughout the Bay Area. Major stations in Martinez and Emeryville feature Coast Starlight and California Zephyr service. The Starlight also serves Oakland and San Jose. The Capitol Corridor connects Bay Area cities to Sacramento and Auburn, California, and features BART transfer stations at Richmond and the Oakland Coliseum. The San Joaquin serves Sacramento, California, and Oakland California with trains to Bakersfield, California.
- ACE - Altamont Commuter Express; a rail service that mainly serves commuters to and from the Central Valley to the Silicon Valley. It travels from Stockton through Pleasanton, Fremont, Santa Clara, and ends at San Jose. It operates only during commute hours on weekdays.
Light rail 
- In San Francisco, Muni operates Muni Metro, a light rail system that runs mostly on converted streetcar lines. It also has a tunnel under Market Street that it shares with BART.

Trans-bay crossings 
San Francisco - Oakland Bay Bridge
|The western terminus of I-80 is located in San Francisco as James Lick Skyway (Bayshore Freeway), just west of the San Francisco – Oakland Bay Bridge. The interstate continues to the east over the bridge, connecting to Oakland and the north coast of the East Bay as the Eastshore Freeway, and then on to Sacramento, Reno, and New Jersey.|
Richmond - San Rafael Bridge
|This spur route's western terminus is in Marin County. The Interstate crosses the San Pablo Bay over the Richmond-San Rafael Bridge, goes through Richmond as the John T. Knox Freeway, passes through Oakland as the MacArthur Freeway, then continues to Livermore, through the Altamont Pass to Tracy, where it intersects with Interstate 5, thus providing a link with Southern California.|
San Mateo - Hayward Bridge
|SR 92's western terminus is in Half Moon Bay. The two-lane highway crosses the Santa Cruz Mountains, connecting to Interstate 280 and U.S. Route 101 as the J.

For most of its route I-280 runs along the foothills of the Santa Cruz Mountains, and is very scenic, while 101 is highly urban and is locally known as "the world's longest parking lot."|
