Transportation in the San Francisco Bay Area


Transportation in the San Francisco Bay Area is reliant on a complex multimodal infrastructure consisting of roads, bridges, highways, rail, tunnels, airports, and bike and pedestrian paths. The development, maintenance, and operation of these different modes of transportation are overseen by various agencies, including the California Department of Transportation, the Association of Bay Area Governments, San Francisco Municipal Transportation Agency, and the Metropolitan Transportation Commission. These and other organizations collectively manage several interstate highways and state routes, two subway networks, two commuter rail agencies, eight trans-bay bridges, transbay ferry service, local bus service, three international airports, and an extensive network of roads, tunnels, and bike paths.
A 2011 Brookings Institution study ranked the San Francisco MSA and the San Jose MSA sixteenth and second, respectively, on transit coverage to job access. Another nationwide study, conducted by the University of Minnesota in 2014, ranked the San Francisco MSA second and San Jose MSA tenth. Despite this, the San Francisco Bay Area remains the second most traffic-congested region in the country with a declining per capita use of public transit.
In 2013, the San Francisco-Oakland-Hayward metropolitan statistical area had the second lowest percentage of workers who commuted by private automobile, with 7.6 percent of area workers traveling via bus. During the period starting in 2006 and ending in 2013, the San Francisco MSA had the greatest percentage decline of workers commuting by automobile among MSAs with more than a half million residents.

Airports

The Bay Area has four airports served by commercial airlines, three of which are international airports. In addition to these airports, there are many general aviation airports in the region.
All major Bay Area airports except Oakland International are situated next to freeways and are served by both public transportation, ride-share services, and various private shuttle bus operators.

Public transportation

Public transportation in the San Francisco Bay Area is quite extensive, including one heavy rail/commuter rail system, one commuter rail line, two light rail systems, Amtrak inter-city rail service, and four major overlapping bus agencies, in addition to dozens of smaller ones. In addition to rail and bus systems, there are multiple public and private ferry services, such as Golden Gate Ferry, which are being expanded by the San Francisco Bay Water Transit Authority. Most of the larger agencies accept the Clipper Card, a reloadable contactless smart card, as a universal electronic payment system.
An extensive rail infrastructure that provides a mix of services exists within the nine Bay Area counties. Bay Area Rapid Transit, commonly known as BART, provides subway service in San Francisco and parts of Oakland and Berkeley, and commuter rail service to Contra Costa County, Alameda County, San Mateo County, and Santa Clara County. Caltrain, which runs on the right-of-way of the historic Southern Pacific Railroad, provides commuter rail service on the San Francisco Peninsula, linking the cities of San Francisco, San Jose, Gilroy, and numerous peninsula cities in between. The Millbrae Intermodal Terminal provides transfers between Caltrain and BART. The Altamont Corridor Express, commonly known as ACE, also provides commuter rail service, but from the Central Valley into Silicon Valley, terminating in the San Jose Diridon Station.
In addition, Amtrak has a presence throughout the Bay Area. Stations in Martinez and Emeryville feature Coast Starlight and California Zephyr service. The Capitol Corridor connects Bay Area cities to Sacramento, and features BART transfer stations at Richmond and the Oakland Coliseum. The Bay Area also has two light rail systems: one run by San Francisco Municipal Railway called Muni Metro, which operates within the city of San Francisco, and the other run by the Santa Clara Valley Transportation Authority, which operates within Santa Clara County.
A series of overlapping bus agencies provide additional public transit coverage to Bay Area regions both served and not served by rail transit. The four largest agencies, Muni, AC Transit, SamTrans, and VTA operate within the City of San Francisco, East Bay, the Peninsula, and South Bay respectively, although their service areas generally overlap with neighboring agencies and numerous smaller agencies. All of these agencies also provide limited night bus service, which are intended to "shadow" the rail routes that are closed during the nighttime hours for maintenance. In addition, the four bus agencies are each independently pursuing constructing bus rapid transit systems by developing separated right-of-ways and traffic signaling on busy corridors, including on Geary and Van Ness for Muni, El Camino Real for SamTrans and VTA, and International Boulevard for AC Transit.
Although BART and certain bus agencies provide travel over the San Francisco bay, Golden Gate Transit also runs the Golden Gate Ferry, which along with private operators Blue & Gold Fleet and Red & White Fleet provide ferry service across the bay. The ferry, along with all the major train and bus operators, allow bicycles onto their systems with no additional charge. In addition, Bay Area residents may rent bicycles from the Bay Area Bike Share in certain parts of San Francisco, San Mateo, and Santa Clara counties.
Until 1971 the Southern Pacific Railroad operated from its Third and Townsend Depot commuter trains to San Jose and long distance trains to Los Angeles.

Bus services and stations

The Transbay Terminal serves as the terminus for long-range bus service and as a hub for regional bus systems AC Transit, WestCAT, SamTrans, and Golden Gate Transit.
Megabus recently relaunched intercity bus service in California and Nevada. San Francisco riders can choose from three routes. The San Francisco stop is located in front of the Caltrain Station. Other intercity bus services include California Shuttle Bus, Hoang Transportation, and USAsia.
There are several bus stations in the San Francisco Bay Area including Fairfield Transportation Center, Richmond Parkway Transit Center, Naglee Park and Ride, Hercules Transit Center, Curtola Park & Ride, Eastmont Transit Center, San Rafael Transit Center and many bus bays at BART stations.

Major bus agencies

Minor bus agencies

Other transit agencies that serve parts of the Bay Area include San Benito Transit, Stanislaus Regional Transit, San Joaquin RTD, Rio Vista Delta Breeze, Mendocino Transit, and Santa Cruz Metro
Private bus companies put an additional 800 buses, often referred to as tech shuttles, on the road per day. If combined, private shuttles would be the 7th largest transportation provider in the Bay Area.

Ferries

There are also private ferries from Emeryville, Berkeley, and Richmond.

Bike and Scooter Sharing

is a regional public bicycle sharing system that serves the cities of San Francisco, Oakland, Berkeley, Emeryville, and San Jose.
The bicycles are available 24 hours a day, seven days a week to anyone who purchases a membership, with three options, annual fee of, for three days or for 24 hours. Any rider may take unlimited trips of up to 30 minutes, as measured from the time the bike is withdrawn from a dock to the time it is returned. Bikes can be picked up at any of the stations using a key fob or electronic code, and dropping them off at any station. Longer trips incur additional fees starting at for the first additional half-hour, since the idea of bike sharing is to make bicycles available for short trips. A replacement fee of $1,200 is charged if a rented bike is lost.
Several companies also operate dockless bicycle sharing systems in the Bay Area such as Jump Bikes, Lime, and Spin. These dockless systems differ from the Ford GoBike system in that bicycles can be parked freely on the street and do not need to be docked at a designation station. Currently, Jump is the only dockless bicycle sharing company that operates in San Francisco while other competing companies operate dockless systems in other Bay Area cities such as South San Francisco, Oakland, and San Jose.
In 2018, several companies started offering dockless scooter-sharing systems in Bay Area cities such as San Francisco and Oakland. These systems offer electric kick scooters for rent, similar to dockless bicycle sharing systems. Some operators, such as Lime, operate both scooter and bicycle sharing systems. These shared scooters were temporarily banned in San Francisco during summer 2018, but as of 2018 are available under two operators: Skip and Scoot Networks.

Public Transportation Statistics

Named interchanges

The Alemany Maze is the interchange between the James Lick Freeway and Interstate 280.
The MacArthur Maze is the interchange between the Eastshore Freeway, Nimitz Freeway, and MacArthur Freeway at the east end of the Bay Bridge.
The Joe Colla Interchange is the interchange between US 101, I-280, and I-680. Both I-280 and I-680's southern termini is located as this interchange.

San Francisco streets

Due to its unique geography, and the freeway revolts of the late 1950s, San Francisco is one of the few American cities with arterial thoroughfares instead of having numerous highways within the city.
Interstate 80 begins at the approach to the Bay Bridge and is the only direct automobile link to the East Bay. U.S. Route 101 connects to the western terminus of Interstate 80 and provides access to the south of the city along San Francisco Bay toward Silicon Valley. Northward, the routing for U.S. 101 uses arterial streets Mission Street and South Van Ness Avenue, Van Ness Avenue, Lombard Street, Richardson Avenue, and Doyle Drive to connect to the Golden Gate Bridge, the only direct automobile link to Marin County and the North Bay.
is the only road connection from San Francisco to the North Bay.
State Route 1 also enters San Francisco from the north via the Golden Gate Bridge, but turns south away from the routing of U.S. 101, first onto Park Presidio Blvd through Golden Gate Park, and then bisecting the west side of the city as the 19th Avenue arterial thoroughfare, joining with Interstate 280 at the city's southern border. Interstate 280 continues south from San Francisco. Interstate 280 also turns to the east along the southern edge of the city, terminating just south of the Bay Bridge in the South of Market neighborhood. After the 1989 Loma Prieta earthquake, city leaders decided to demolish the Embarcadero Freeway, and a portion of the Central Freeway, converting them into street-level boulevards.
State Route 35 enters the city from the south as Skyline Boulevard, following city streets until it terminates at its intersection with Highway 1. State Route 82 enters San Francisco from the south as Mission Street, following the path of the historic El Camino Real and terminating shortly thereafter at its junction with 280. Major east–west thoroughfares include Geary Boulevard, the Lincoln Way/Fell Street corridor, and Market Street/Portola Drive.
The Western Terminus of the historic transcontinental Lincoln Highway, the first road across America, is in San Francisco's Lincoln Park.

San Francisco Bay Trail

The San Francisco Bay Trail is a bicycle and pedestrian trail that will eventually allow continuous travel around the shoreline of San Francisco Bay. As of 2016, 350 miles of trail have been completed, while the full plan calls for a trail over 500 miles long that link the shoreline of nine counties, passing through 47 cities and crossing seven toll bridges. Sections of the Bay Trail exist in all nine Bay Area counties. The longest continuous segments include 26 miles primarily on gravel levees between East Palo Alto and San Jose in Santa Clara County; 25 miles in San Mateo County between Millbrae and San Carlos; 17 miles in central Alameda County from San Leandro to Hayward; and 15 miles along the shoreline and on city streets through Richmond in Contra Costa County. The northernmost trail section passes through San Pablo Bay National Wildlife Refuge.

Bridges

Due to the central location of the San Francisco Bay, eight toll bridges cross the Bay or Bay tributaries. Each of the bridges collect separate tolls, and all of them accept payment through FasTrak, an electronic toll collection system used in the state of California. Seven of these eight bridges are owned directly by the State of California, while the Golden Gate Bridge is owned and operated by the Golden Gate Bridge, Highway and Transportation District.

Seaports

The Port of San Francisco was once the largest and busiest seaport on the West Coast. It featured rows of piers perpendicular to the shore, where cargo from the moored ships was handled by cranes and manual labor and transported to nearby warehouses. The port handled cargo to and from trans-Pacific and Atlantic destinations, and was the West Coast center of the lumber trade. The 1934 West Coast Longshore Strike, an important episode in the history of the American labor movement, brought most ports to a standstill. The advent of container shipping made pier-based ports obsolete, and most commercial berths moved to the Port of Oakland and Port of Richmond. A few active berths specializing in break bulk cargo remain alongside the Islais Creek Channel.
The port currently uses Pier 35 to handle the 60–80 cruise ship calls and 200,000 passengers that come to San Francisco. Itineraries from San Francisco usually include round trip cruises to Alaska and Mexico. The James R. Herman Cruise Terminal Project at Pier 27 opened in 2014 as a replacement. The previous primary terminal at Pier 35 had neither the sufficient capacity to allow for the increasing length and passenger capacity of new cruise ships nor the amenities needed for an international cruise terminal.
On March 16, 2013, Princess Cruises Grand Princess became the first ship to home port in San Francisco year round. The ship offers cruises to Alaska, California Coasts, Hawaii, and Mexico. Grand Princess will be stationed in San Francisco until April 2014. Princess will also operate other ships during the summer of 2014, making it the only cruise line home porting year round in San Francisco.
