The section between the Golden Gate Bridge (including an upgraded Doyle Drive) and Van Ness Ave. The proposed section as replanned in 1964 would have extended not from the Lombard Street exit of Doyle Drive along Lombard Street as originally planned in 1955, but from the Marina Boulevard exit off Doyle Drive, through the Marina Green and then along the north side of Fort Mason, then along the north side of Bay Street to the Embarcadero and south along the Embarcadero to connect with the Embarcadero Freeway. Poet Kenneth Rexroth spoke at the rally (among others), and folk singer Malvina Reynolds sang (she was most famous for her song " Little Boxes", attacking urban sprawl, which she sang at the anti-freeway rally). The freeway revolt continued after a new freeway plan was proposed in 1964, with a major protest on May 17, 1964-200,000 people rallied in Golden Gate Park against any more new freeways. The freeway revolt caused the San Francisco Board of Supervisors to pass Resolution 45–59 in January 1959, opposing certain freeways, including the remainder of I-480.

The Clay Street and Washington Street ramps then opened around 1965. The first section of the Embarcadero Freeway, from the Bay Bridge approach ( I-80) near First Street north to Broadway, opened in 1959. The original 1955 plan was to extend the Central Freeway as a double-decked structure between Van Ness Avenue and Polk Street north to Clay Street, then as a single-deck depressed freeway north to Broadway, where it would have tunneled under Russian Hill to connect with I-480. ( I-280, as originally planned, ran south from the west end of I-480 along SR 1, through the MacArthur Tunnel and Golden Gate Park, to join its present alignment in Daly City.) After some discussion, the I-480 number was assigned on November 10, 1958. This included the 1936 Doyle Drive, an early freeway built to access the Golden Gate Bridge. LR 224, as well as Route 2 (US 101) from Route 224 west to the junction with SR 1 near the Golden Gate Bridge, was added to the Interstate Highway System on September 15, 1955. Its alignment was roughly along Lombard Street and the Embarcadero. Route 101 (US 101, pre-1964 Legislative Route 2) at the intersection of Lombard Street and Van Ness Avenue with US 40 and US 50 (pre-1964 Legislative Route 68) at the west end of the San Francisco–Oakland Bay Bridge (near the Transbay Terminal). Legislative Route 224 ( LR 224) was defined in 1947 to connect U.S.

The entire route was removed in 1991, approximately two years after the earthquake.

SR 480 was Interstate 480 ( I-480), an auxiliary route of the Interstate Highway System, from 1955 to 1965. Route 101, until being replaced in 2015 by the Presidio Parkway.

The Embarcadero Freeway, which had only been constructed from Broadway along the Embarcadero to the Bay Bridge, was demolished after the 1989 Loma Prieta earthquake, and Doyle Drive was then part of U.S. The unbuilt section from Doyle Drive to Van Ness Avenue was to have been called the Golden Gate Freeway and the Embarcadero Freeway as originally planned would have extended from Van Ness along the north side of Bay Street and then along the Embarcadero to the San Francisco-Oakland Bay Bridge. State Route 480 ( SR 480) was a state highway in San Francisco, California, United States, consisting of the elevated double-decker Embarcadero Freeway (also known as the Embarcadero Skyway), the partly elevated Doyle Drive approach to the Golden Gate Bridge and the proposed and unbuilt section in between.
