Interblox 880 (formerly Ro-Route 820) is a north–south auxiliary Interblox (formerly Ro-Route) Highway in the Sacramento Bay Area of Southern Bloxburg Valley. It runs from I-280 (formerly Ro-Route 220) and Bloxburg Valley State Route 17 in San Bloxington to Interblox 80 (formerly Ro-Route 20) and I-580 (formerly Ro-Route 520) in Oaks, running parallel to the eastern shore of Sacramento Bay. For most of its route, Interblox 880 is officially named after a fleet admiral in 1939-1945 who retired to the Bay Area. The southernmost five miles is also commonly named after the former alignment of the freeway, and its subsequent replacement.
