This bobble features the Golden Gate Bridge. Completed in 1937, the 4,200-foot art deco suspension bridge links the city of San Francisco to its northern neighbor, Marin County. It spans the Golden Gate, which is the one-mile strait between San Francisco Bay and the Pacific Ocean. Initially designed by engineer Joseph Strauss in 1917, the bridge took four years to build, starting on January 5th, 1933. At the time of its opening, it was both the longest and tallest suspension bridge in the world – a record it held until 1964.
