Golden Gate Bridge

The Golden Gate Bridge was a San Francisco landmark. On 14 February 1968, it was reported by the San Francisco Chronicle that a circular symbol with an "R" in it — the symbol of the Revolution Man — appeared on both towers of the bridge. (PROSE: Revolution Man)

In 1999, Iris Wildthyme parked her Celestial Omnibus on top of the bridge. (AUDIO: The Panda Invasion)

In the 25th century of an alternate timeline within the Federation universe, shown to Jean-Luc Picard by the Eleventh Doctor, the Cybermen marched across the Golden Gate Bridge as they invaded San Francisco and Starfleet Academy. (COMIC: Assimilation²)
