"The MacArthur Maze in the U.S. city of Oakland, California is a freeway interchange next to the San Francisco-Oakland Bay Bridge. Caltrans calls the Maze the distribution structure.[1] However, local traffic reporters and residents generally use "the Maze" to refer to the series of freeway interchanges in that general area. The MacArthur Maze is named after nearby MacArthur Boulevard and the MacArthur Freeway (Interstate 580), which in turn are named after General Douglas MacArthur."

"The MacArthur Maze was originally constructed as part of the construction of the Bay Bridge. It was significantly smaller in scale than today's complex interchanges but at the time was still impressive. There were three principal feeder routes utilizing ramps: a viaduct from the end of Cypress Street (State Highway 17) in Oakland; a viaduct from the end of 38th Street (U.S. Highway 50; 38th was subsequently renamed "MacArthur Boulevard") at San Pablo Avenue in Oakland; and the Eastshore Highway which carried U.S. Highway 40 along the shoreline of Albany, Berkeley, and Emeryville."

[edit] 2007 Fire and Collapse

"At 3:42 am on the morning of April 29, 2007, a tank truck carrying 8,600 gallons (32,500 liters) of unleaded gasoline overturned on the ramp connecting Interstate 80 West (from Berkeley) to Interstate 880 South. The intense heat from the subsequent explosion and fire weakened the steel structure of the roadway above, which served as the connecting ramp from Interstate 80 East (from San Francisco) to Interstate 580 East (to Oakland), collapsing approximately 250 yards (229 m) of it onto the lower connector."
