Golden Gate Bridge,San Francisco, US ( One of the world's most beautiful bridges)

Golden Gate Bridge is one of the most internationally recognized symbols of San Francisco, California, and the United States. It has been declared one of the Wonders of the Modern World by the American Society of Civil Engineers. 

In 1916, the idea of a bridge to cross the Golden Gate, a narrow strait that separated San Francisco Peninsula and the Marin Headlands, was conceived. Though it was almost immediately dismissed as the cost was estimated to be $100 million (astronomical for the time), a veteran bridge builder named Joseph Strauss lobbied for more than two decades to have it built.
