Oakland - a portion of the MacArthur Maze

Oakland:  80 and 880 and 580 Freeways
18" x 13.5"

The MacArthur Maze refers to the freeway interchange located near the eastern end of the San Francisco – Oakland Bay Bridge in Oakland, California; it is the largest freeway interchange in the world.

In 1989, the Loma Prieta earthquake caused a double-decked section of the Maze to collapse, crushing cars.  The three miles of replacement freeway cost $1.2 billion.

In 2007, a speeding tanker truck carrying gasoline hit a guardrail and overturned on a Maze connector.  The driver walked away with minor injuries. The intense heat from the subsequent fuel spill and fire weakened the steel structure of the roadway above, collapsing it onto the lower connector, which sank nine inches.  A state projection concluded that the connector collapse had cost $90 million.  The company that owned the tanker truck lost its license to transport gasoline.
