San Francisco Transbay Terminal was the principal downtown San Francisco bus depot and regional transit hub from 1939 until its closure in 2010, succeeded by the Salesforce Transit Center in 2018. The terminal served as a focal point for intermodal transfers among San Francisco Municipal Railway, Interstate 80, U.S. Route 101, State Route 1 (California), AC Transit, Golden Gate Transit, Amtrak Thruway Motorcoach, and Greyhound Lines. Located at Howard and First Streets in the South of Market neighborhood, the terminal played a critical role in Bay Area transportation planning, redevelopment debates, and seismic retrofitting efforts during the late 20th and early 21st centuries.
History
The terminal opened in 1939 as part of New Deal-era infrastructure and regional planning linked to San Francisco Bay crossings, replacing primitive ferry-to-bus transfers and reflecting influences from Electrification, Great Depression public works, and California Department of Transportation priorities. Early operations connected downtown San Francisco to the East Bay, Marin County, Peninsula (San Francisco Bay Area), and South Bay via bus services operated by companies such as Key System, Southern Pacific Transportation Company, and later AC Transit and Greyhound Lines. Post‑World War II suburbanization, the construction of the Bay Bridge, and changes to regional transit patterns transformed the terminal into a busy intermodal hub, while debates involving the San Francisco Redevelopment Agency, Transbay Joint Powers Authority, and municipal leaders shaped proposals for replacement and expansion throughout the late 20th century.
Design and Construction
The original terminal's architecture reflected mid‑20th century functionalism with bus berths, passenger concourses, and rooftop staging influenced by engineering practices from firms associated with large transit projects like Bechtel Corporation and Skidmore, Owings & Merrill. Structural design addressed proximity to the Embarcadero Freeway and considerations about the San Andreas Fault and regional seismicity following events such as the 1906 San Francisco earthquake and later the 1989 Loma Prieta earthquake. Funding and construction phases involved stakeholders including Caltrans (California Department of Transportation), the Metropolitan Transportation Commission (California), and local elected officials such as members of the San Francisco Board of Supervisors. Plans for a new center incorporated input from architecture firms, urban planners, and transit agencies including HNTB Corporation and Fentress Architects during the 1990s and 2000s.
Facilities and Operations
The terminal provided multiple bus platforms, ticketing areas, passenger waiting rooms, and interline transfer facilities serving operators like AC Transit, Golden Gate Transit, SamTrans, VTA, and regional carrier services such as Amtrak California. Operational control involved scheduling coordination with agencies including the Association of Bay Area Governments and transit security provided by municipal and regional police forces such as the San Francisco Police Department and Bay Area Rapid Transit Police Department. Ancillary facilities included maintenance access, fare collection infrastructure compatible with fare systems like Clipper (card), and ADA accessibility upgrades prompted by federal laws such as the Americans with Disabilities Act of 1990.
Services and Connections
As a primary gateway for commuters, the terminal linked bus routes to ferry terminals at Ferry Building (San Francisco), Pier 39, and regional railheads such as Caltrain Depot and Embarcadero Station. Connections enabled transfers to Bay Area Rapid Transit services across Powell Street station, Montgomery Street station, and Embarcadero (BART station), while facilitating long‑distance bus services to destinations including Los Angeles Union Station, Sacramento–Amtrak Station, and the Central Valley. The terminal integrated with regional planning initiatives such as Plan Bay Area and supported special event transit operations for venues like Oracle Park and Chase Center (San Francisco). Commuter flows were shaped by land uses in South of Market (SoMa), the Financial District, San Francisco, and redevelopment projects tied to agencies like the Transbay Joint Powers Authority.
Transit Center Redevelopment and Salesforce Transit Center
Longstanding proposals culminated in the transit center redevelopment led by the Transbay Joint Powers Authority to replace the aging terminal and extend rail via the Caltrain Downtown Extension and California High‑Speed Rail. The new facility, opened as the Salesforce Transit Center, incorporated a rooftop park, expanded bus platforms, and preparations for a future railway terminus connected to the Transbay Transit Center (rail) project. Major stakeholders included Salesforce, which acquired naming rights, construction contractors such as Webcor Builders, and design teams including Pelli Clarke Pelli Architects. Project milestones intersected with funding mechanisms like federal transportation grants from the United States Department of Transportation and local bond measures administered by the Metropolitan Transportation Commission (California) and county transportation authorities.
Controversies and Incidents
The terminal replacement and Salesforce Transit Center faced controversies including cost overruns, construction delays, and political debates involving the San Francisco Mayor's Office, the San Francisco Board of Supervisors, and regional transit agencies. Structural issues discovered in the new center, notably cracked steel support beams, prompted investigations by regulatory bodies such as the National Transportation Safety Board and enforcement actions involving the Cal/OSHA and led to temporary closures affecting operators like AC Transit and Greyhound Lines. Litigation and public scrutiny involved contractors, insurers, and stakeholder entities including private donors and corporate partners such as Salesforce and prompted renewed focus on seismic safety standards influenced by codes from the American Society of Civil Engineers and state building regulations administered by California Building Standards Commission.
