head west and north around the periphery of downtown San Francisco. This portion would include junctions with the Mission Freeway (south and southwest along Mission Street to Daly City) at the southwest corner and the Panhandle Freeway (west through the Panhandle into Golden Gate Park) along the west side. After swinging northeast and back north to the east side of Van Ness Avenue (continuing as a double-decked structure between Van Ness Ave. and Polk Street), a pair of ramps would split to the east, taking downtown traffic to and from the one-way pair of Bush and Pine Streets. At Clay Street, the freeway would descend to meet the rising terrain, ending at Broadway just east of Van Ness Avenue as a single level depressed roadway. A short tunnel would curve northwest to a portal in Van Ness Avenue north of Broadway, taking traffic onto Van Ness Avenue towards the Golden Gate Bridge. Along with the Embarcadero and Broadway Tunnel, which were listed for rebuilding as ground-level expressways rather than the freeway (Embarcadero Freeway) that was later partially built and demolished, the Central Freeway would have provided a full traffic distributor loop around downtown. The route was also included in the 1955 city master plan, by then extending north beyond the former Broadway terminus to the proposed Golden Gate Freeway near Lombard Street. The first piece, connecting the Bayshore Freeway with Mission Street, opened March 1, 1955, at about the same time as the Bayshore. The part of the Central Freeway to the one-way pair of Golden Gate Avenue and Turk Street opened in April 1959, and became part of U.S. Route 101 (and Legislative Route 2) via this one-way pair to the old route on Van Ness Avenue. In January of that year, as one of the opening events in the freeway revolts, the San Francisco Board of Supervisors passed Resolution 45-59, removing the remainder of the Central Freeway and most other proposed freeways from the city's highway plan. Interstate 80, which had been assigned to the Central Freeway southeast of the proposed Panhandle Freeway, was truncated by the Federal Highway Administration in August 1965 and by the state in 1968. There was a plan promulgated in February 1962 to relieve traffic congestion on the Golden Gate Bridge by constructing a "San Francisco-Tiburon Bridge" from Van Ness Ave. at Aquatic Park in San Francisco north across the Golden Gate Strait
