Golden Gate Bridge : San Francisco
The Golden Gate Bridge is a suspension bridge spanning the Golden Gate strait, the one-mile-wide channel between San Francisco Bay and the Pacific Ocean. The bridge opened in 1937 and was, until 1964, the longest suspension bridge main span in the world, at 4,200 feet (1,300 m).
The structure links the city of San Francisco to Marin County. The bridge is one of the most internationally recognized symbols of San Francisco and the United States. It has been declared one of the Wonders of the Modern World by the American Society of Civil Engineers.
The color of the bridge is officially an orange vermilion and was selected by consulting architect Irving Morrow because it complements the natural surroundings and enhances the bridge's visibility in fog.
Sausalito (Center Left) is a San Francisco Bay Area city in Marin County, California. The community is situated near the northern end of the Golden Gate Bridge, and prior to the building of that bridge served as a terminus for rail, car, and ferry traffic. Developed rapidly as a shipbuilding center in World War II, the city's industrial character gave way in postwar years to a reputation as a wealthy and artistic enclave, a picturesque residential community (incorporating large numbers of houseboats), and a tourist destination. It is adjacent to, and largely bounded by, the protected spaces of the Golden Gate National Recreation Area.
Alcatraz Island was developed with facilities for a lighthouse, a military fortification, a military prison (1868), and a federal prison from 1933 until 1963.
In 1972, Alcatraz became a national recreation area and received designation as a National Historic Landmark in 1986.
Today, the island's facilities are managed by the National Park Service as part of the Golden Gate National Recreation Area; it is open to tours.
