The MacArthur Maze (formerly known as the Distribution Structure) began as part of the Bay Bridge construction project in the 1930s. Over the years, it expanded to include the labyrinth of highway interchanges that today’s drivers know all too well. I-80, 580 and 880 come together in a big, sweeping maze just before splitting off towards all points South, East and West.
In the past few years, the MacArthur Maze has proven to be just as resilient as its home city. The interchange has survived earthquakes, fires, and millions of daily commuters.
In 2007, a tanker full of gasoline overturned on a portion of the maze. The ensuing fire was hot enough to weaken the steel, and caused a chunk of the overpass to collapse. Fortunately, nobody was hurt and Caltrans managed to rebuild and re-open the maze in just 26 days. The fast-tracked construction project was so remarkable that a team of Emmy-winning documentary filmmakers covered its progress. The documentary, Amazing ran on TV stations across the state.
