Now a part of I-80 between Davis and Roseville, Interstate 880 was the previous designation for the north Sacramento bypass in central California. It was eliminated with the relocation of I-80 approved by the American Association of State Highway and Transportation Officials (AASHTO) on November 14, 1980. The renumbering took place after the planned 5.1 realignment of I-80 from them substandard Elvas Freeway through north Sacramento was cancelled in 1979.1
The Federal Highway Administration (FHWA) approved the withdrawal of the unconstructed section of I-80 from the Interstate System on May 15, 1980. I-80 was rerouted over Interstate 880 to maintain route continuity.1 Signs changes were finalized in 1982.
I-880 north of Sacramento was an original Interstate highway, established in July 1958. The freeway was completed in sections from West Sacramento to SR 244 between June 1970 and October 1971.
