MacArthur Maze
interchange in California

The MacArthur Maze (or more simply the Maze; formally, the East Bay Distribution Structure) 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).
Description
San Francisco Bay Area traffic funnels across the few bridges spanning the bay, so the Maze's central location near the east end of the San Francisco–Oakland Bay Bridge makes it a hub for east–west and north–south traffic to and from San Francisco and Oakland. It sits next to the Port of Oakland, the fourth-busiest container port in the United States.
Four freeways intersect at this interchange:
I-80 west (Bay Bridge)
Interstate 80 from the Maze heads west onto the Bay Bridge across the bay toward San Francisco, where it joins US 101.
I-80 east / I-580 west (Eastshore Freeway) – Berkeley, Sacramento, San Rafael
The Interstate 80/Interstate 580 wrong-way concurrency from the Maze heads north through Berkeley and western Contra Costa County. Just north of the Berkeley-Albany border, about 4 miles (6.4 km) north of the Maze, the concurrency splits. Interstate 80 heads northeast towards Sacramento. Interstate 580 heads northwest towards the Richmond-San Rafael Bridge and eventually to Marin County, where it joins U.S. 101 in San Rafael.
I-580 east (MacArthur Freeway) to SR 24 / I-980 – Downtown Oakland, Walnut Creek, Hayward, Stockton
Interstate 580 from the Maze heads southeast through Oakland.
This brief starts where responsible research should: with the source description of “MacArthur Maze” as interchange in California. Everything that follows is an evidence route, not borrowed authority.
Why this record matters
The subject matters to the general reference register because the source frames it as interchange in California. Its deeper value depends on whether names, dates, institutions and citations support that framing.
Vocabulary and entity names are the principal evidence signals here, because they determine the precision of every later search. The source revision retrieved here is dated Jul 21, 2026. The linked authority identifier is Q806049.
A concise general-reference account can conceal disagreements about scope, terminology or the weight assigned to individual sources. The lead is largely declarative, so disagreement and counter-evidence require a deliberate search beyond the opening account. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
