The Golden Gate is the North American strait that connects San Francisco Bay to the Pacific Ocean. Since 1937, it has been spanned by the Golden Gate Bridge. Technically, the 'gate' is defined by the headlands of the San Francisco Peninsula and the Marin Peninsula, while the 'strait' is the water that flows in between.[citation needed]
The Golden Gate Bridge is a suspension bridge spanning the Golden Gate, the opening of the San Francisco Bay into the Pacific Ocean. As part of both U.S. Route 101 and California State Route 1, the structure links the city of San Francisco, on the northern tip of the San Francisco Peninsula, to Marin County. It 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. The Frommers travel guide considers the Golden Gate Bridge "possibly the most beautiful, certainly the most photographed, bridge in the world".
