San Francisco Muni Railway Lines circa 1915
J Thoendell stashed this in Maps
Most current San Francisco residents are probably familiar with the F-Market streetcar line. The F-Market line, though completed in 1995, pays homage to the many streetcar lines that crossed San Francisco in the early 1900s. The A, B, C and D lines traversed from the Ferry Building west down Market and Geary, while the E, F and H lines ran to Fort Mason, the Marina and the Presidio. By 1915, San Francisco finally had the infrastructure to transport large numbers of people to the northern shore where the fair would take place, an area that had previously been a mishmash of the Presidio military base, tide pools, landfill and industrial buildings.
Thank you for the history lesson. Hard to believe that infrastructure is a century old.
TL;DR = Nimbys suck.
