The Tool Box was a leather bar for gay men in San Francisco that operated from 1962 to 1971 on the east corner of 4th Street and Harrison Street. It was the first leather bar in the South of Market, and a meeting spot where influential personalities of the early San Francisco leather scene gathered. After a prominent feature in Life magazine in 1964, it was considered the archetypal leather bar, helping to cement San Francisco's reputation as the “gay capital” of the US. The bar's history was short-lived: from 1965 onwards, the epicenter of the leather scene shifted towards Folsom Street (most notably Febe's bar), which ultimately led to its closing in 1971. The Tool Box is commemorated at the San Francisco South of Market Leather History Alley. The patronage of the Tool Box included influential personalities of the early San Francisco leather scene, among others artist Bill Tellman, Jack H. (owner of the Detour and the Slot, co-owner of Febe's), artist Mike Caffee (creator of the logo and a statue for Febe's), as well as the Satyrs Motorcycle Club (oldest gay motorcycle club in the US) from Los Angeles. The artist Chuck Arnett also worked as a bartender at the Tool Box. On June 26th 1964, Life magazine published a cover story titled "Homosexuality in America", which not only brought San Francisco as a hub of gay life into public consciousness, but also the Tool Box. The article opened with a two-page photo-spread of its interior with patrons dressed in leather beneath a mural, photographed by Bill Eppridge. In the 1991 anthology, Leatherfolk, Jack Fritscher described the article as "an image-liberating historical issue that was read across the nation as an invitation to come to San Francisco and be a man's man." The article also included an interview with Bill Ruquy, part owner of the bar, who detailed the strict dress code that excluded tennis shoes among other garments that didn't fit the biker aesthetic. Especially for queer men living in conservative small towns, the publication shed a spotlight on this gay subculture of butch leathermen, who did not fit the widespread clichés of the 'effeminate homosexual'—and where to find them. Thus, the Life piece unintentionally became an advertisement for the leather scene and ultimately a catalyst of gay emancipation. Drummer magazine dedicated an article about the demolition of the Tool Box in its second volume in August 1975, titled "Requiem for a toolbox". This further illustrates the importance that contemporaries awarded to the Tool Box's role in gay leather history.

The Central Subway is an extension of the Muni Metro light rail system under construction in San Francisco, California, from the Caltrain commuter rail depot at 4th and King streets to Chinatown, with stops in South of Market (SoMa) and Union Square. The subway is the second phase of the San Francisco Municipal Transportation Agency's Third Street Light Rail Project. The first phase opened to the public as the T Third line in 2007. Ground was broken for the Central Subway on February 9, 2010. Tunnel boring for the Central Subway was completed at Columbus and Powell Street in the North Beach neighborhood of San Francisco on June 11, 2014. Originally set to open in late 2018, the Central Subway is (as of December 2021) projected to open to the public in October 2022. With the addition of the Central Subway, the T Third line is projected to become Muni Metro system's highest ridership line by 2030.The extension will serve major employment and population centers in San Francisco that are underserved by rapid transit. SoMa is home to the headquarters of many of San Francisco’s major software and technology companies, and substantial residential growth is projected there. Union Square, located in the city's downtown, is a primary commercial and economic district. Chinatown is the most densely populated neighborhood in the city. The Central Subway will connect these areas to communities in eastern San Francisco, including Mission Bay, Dogpatch, Bayview–Hunters Point and Visitacion Valley. The project was initiated after the Embarcadero Freeway was torn down following the 1989 Loma Prieta earthquake, when activist Rose Pak "almost single-handedly persuaded the city to build" the Central Subway to compensate Chinatown for the loss of the fast cross-town connection.The budget to complete the Central Subway is $1.578 billion. The project is funded primarily through the Federal Transit Administration’s New Starts program. In October 2012, the FTA approved a Full Funding Grant Agreement, the federal commitment of funding through New Starts, for the Central Subway for a total amount of $942.2 million. The Central Subway is also funded by the State of California, the Metropolitan Transportation Commission, the San Francisco County Transportation Authority and the City and County of San Francisco.
