Historical Background

Early Visions and Proposals (1900s–1930s)

The dream of a subway beneath Market Street originated in the early 20th century, as city leaders sought to alleviate the mounting congestion of cable cars, horse-drawn vehicles, and electric streetcars (SFMTA). By 1918, four tracks spanned Market Street, serving both the Municipal Railway (Muni) and the private Market Street Railway Company (Wikipedia). In 1930, City Engineer Michael O’Shaughnessy envisioned a multi-track subway with close-spaced stations and connections to existing tunnels (Streetcar.org). However, political and financial roadblocks, especially the dominance of private transit operators, delayed progress for decades.

Postwar Momentum and the BART Era (1940s–1960s)

After World War II, San Francisco’s growing population and traffic congestion revived the push for underground rapid transit. The formation of the Bay Area Rapid Transit (BART) District in the late 1950s culminated in the 1962 voter approval of a bond issue to fund both BART and a two-level Market Street Subway. The lower level would accommodate BART trains, while the upper level would serve Muni’s light rail vehicles (Streetcar.org; Wikipedia).

Engineering Challenges, Construction, and Modernization (1967–Present)

Construction began in 1967, employing the cut-and-cover method and contending with hundreds of utility lines and challenging soil conditions (FoundSF). The project’s engineering feats included slurry walls, deep pilings, and complex tie-ins with the Transbay Tube under San Francisco Bay. Despite delays caused by vehicle procurement and operational compromises, the subway’s first official ride took place in 1978, and full service began by 1980 (SFMTA; Railway Age; Streetcar.org). Integration with the Central Subway and ongoing modernization efforts, including upgrades to accessibility and infrastructure, continue to shape the subway’s role today.
