The short piece of I-280 between 3rd Street and SR 480 in downtown San Francisco was never built, and the piece from 5th Street south to U.S. Route 101 originally terminated mid-air, to connect to the second proposed location of a parallel bay bridge (which was never built) but was reconfigured to the King St on/off ramps after it was damaged by the 1989 earthquake. The piece between SR 480 and I-80 was torn down along with the rest of the Embarcadero Freeway; ramp stubs which would have connected the freeways were removed as part of the San Francisco–Oakland Bay Bridge Western Approach reconstruction project.
