Interstate 80, a major east-west route of the Interstate Highway System, has its western terminus in San Francisco, California, United States. From San Francisco it heads east across the Bay Bridge to Oakland, where it turns north and crosses the Carquinez Bridge before turning back northeast and east through Sacramento. I-80 crosses into Nevada west of Reno, Nevada.

[edit] West end in San Francisco

The start of Interstate 80 (actually State Route 80) in San Francisco

Signage takes I-80 to a west end at U.S. Route 101 in San Francisco. However, the James Lick Skyway is not part of the Interstate Highway System; the Interstate actually begins at the west end of the Bay Bridge, at the ramps formerly connecting to the Embarcadero Freeway (originally planned as a connection to Interstate 480). As such the first 1.20 miles of the signed Interstate are not officially an Interstate Highway according to the federal government, however the state of California does consider the first 1.2 miles part of Interstate 80.

When I-80 was first approved, it was to head north on the Central Freeway (US 101) and west on the never-built Panhandle Freeway, ending at planned I-280 (State Route 1) in Golden Gate Park. A January 1968 amendment moved I-280 to its present alignment, removed Interstate 480, and truncated I-80 to the Embarcadero Freeway (then I-280, formerly I-480).^[2] 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 James Lick Skyway, which had already been signed as part of I-80, has remained a de facto section of Interstate 80 to the present day and remains listed as part of Route 80 in California.

[edit] State law

Route 80 is part of the Freeway and Expressway System, as stated by section 253.1 of the California State Highway Code.
