When I-80 was first approved, it was to begin at planned I-280 (SR 1) in Golden Gate Park, head east on the never-built Panhandle Freeway, then run south and southeast on the Central Freeway (US 101) to the San Francisco Skyway. The Panhandle Freeway was to be routed through Hayes Valley, passing through Golden Gate Park and terminating at proposed I-280, now SR 1. In 1964, community oppositions forced CalTrans to abandon the Panhandle Freeway project. A January 1968 amendment moved I-280 to its present alignment, degraded Interstate 480, to a state highway, and truncated the origin point of I-80 to the Embarcadero Freeway (then I-280, formerly I-480). Prior to that truncation, I-80 had been defined as from "Route 280 in San Francisco to the Nevada state line near Verdi, Nevada, passing near Division Street in San Francisco, passing near Oakland, via Albany, via Sacramento, passing near North Sacramento, passing near Roseville, via Auburn, via Emigrant Gap, via Truckee and via the Truckee River Canyon," and certain maps had been shown of I-80 running concurrently with US 101 to Fell Street. These changes were made on the state level later that year, but Route 80 was only truncated to US 101. (The Central Freeway remained part of US 101, and the Panhandle Freeway became "State Route 241". The Panhandle Freeway was later cancelled in the wake of the Freeway Revolts, and the State Route 241 designation has since been reassigned to an unrelated stretch of highway in Orange County) The San Francisco Skyway, which had already been signed as part of I-80, has remained a de facto section of I-80 to the present day and remains listed as part of the Interstate in California.
