The MacArthur Maze is a large freeway interchange in Oakland, California. It splits traffic coming off the east end of the San Francisco–Oakland Bay Bridge into three freeways: the Eastshore (I-80/I-580), MacArthur (I-580) and Nimitz (I-880).

The San Francisco–Oakland Bay Bridge, known locally as the Bay Bridge, is a complex of bridges spanning San Francisco Bay in California. As part of Interstate 80 and the direct road between San Francisco and Oakland, it carries about 260,000 vehicles a day on its two decks. It includes one of the longest bridge spans in the United States.
