San Francisco's Golden Gate Bridge, a stunning technological and artistic achievement, opens to the public after five years of construction. On opening day--"Pedestrian Day"--some 200,000 bridge walkers marveled at the 4,200-foot-long suspension bridge, which spans the Golden Gate Strait at the entrance to San Francisco Bay and connects San Francisco and Marin County. On May 28, 1937 the Golden Gate Bridge opened to vehicular traffic.

The concept of bridging the nearly mile-wide Golden Gate Strait was proposed as early as 1872, but it was not until the early 1920s that public opinion in San Francisco began to favor such an undertaking. In 1921, Cincinnati-born bridge engineer Joseph Strauss submitted a preliminary proposal: a combination suspension-cantilever that could be built for $27 million. Although unsightly compared with the final result, his design was affordable, and Strauss became the recognized leader of the effort to bridge the Golden Gate Strait.

During the next few years, Strauss' design evolved rapidly, thanks to the contributions of consulting engineer Leon S. Moisseiff, architect Irving F. Morrow, and others. Moisseiff's concept of a simple suspension bridge was accepted by Strauss, and Morrow, along with his wife, Gertrude, developed the Golden Gate Bridge's elegant Art Deco design. Morrow would later help choose the bridge's trademark color: "international orange," a brilliant vermilion color that resists rust and fading and suits the natural beauty of San Francisco and its picturesque sunsets. In 1929, Strauss was selected as chief engineer.

To finance the bridge, the Golden Gate Bridge and Highway District was formed in 1928, consisting of San Francisco, Marin, Sonoma, Del Norte, and parts of Mendocino and Napa counties. These counties agreed to collectively take out a large bond, which would then be paid back through bridge tolls. In November 1930, residents of the Golden Gate Bridge and Highway District voted 3-1 to put their homes, farms, and businesses up as collateral to support a $35 million bond to build Strauss' Golden Gate Bridge.

Construction began on January 5, 1933, at the height of the Great Depression. Strauss and his workers overcame many difficulties: strong tides, frequent storms and fogs, and the problem of blasting rock 65 feet below the water to plant earthquake-proof foundations. Eleven men died during construction. On May 27, 1937, the Golden Gate Bridge was opened to great acclaim, a symbol of progress in the Bay Area during a time of economic crisis. At 4,200 feet, it was the longest bridge in the world until the completion of New York City's Verrazano-Narrows Bridge in 1964. Today, the Golden Gate Bridge remains one of the world's most recognizable architectural structures.

Once called "the bridge that couldn't be built," today it is one the seven wonders of the modern world. This magnificent span, perhaps San Francisco's most famous landmark, opened in 1937 after a four-year struggle against relentless winds, fog, rock and treacherous tides.

Crossing the strait of the Golden Gate from San Francisco to the Marin headlands for 1.7 miles is the world-renowned Golden Gate Bridge, easily identified by its International Orange color. Opened in 1937, the bridge was built at a cost of $35 million in principal and $39 million in interest and 11 workers’ lives. The single-suspension span is anchored by twin towers that reach skyward 746 feet, and was once taller than any building in San Francisco. To support the suspended roadway, two cables, each more than 7,000 feet in length and both containing 80,000 miles of wire stretch over the top of the towers and are rooted in concrete anchorages on shore. More than 10 years in planning due to formidable opposition, but only four years in actual construction, the Golden Gate Bridge brought the communities of San Francisco and Marin counties closer together.

Pedestrians including wheelchair users and bicyclists can go on the sidewalks of the bridge during daylight hours but roller blades, skateboards and roller skates are not permitted. There are vista points on both north and south sides of the bridge with parking lots.

The Golden Gate Bridge has lost 7,500 tons (in weight) since it opened in 1937.

It is estimated that 5,000 - 10,000 gallons of paint are used to repaint the Golden Gate Bridge each year.

Three babies have been born on the Golden Gate Bridge. All of them have been boys.

The name came from the fact that the Golden Gate Strait (named by John Fremont) is the entrance into San Francisco Bay from the Pacific Ocean.

International Orange was selected as the color of the bridge because it provided visibility in the fog for passing ships and also because it was a color that fit in naturally to the bridge’s setting and the surrounding land area.

The bridge has only been closed three times due to weather since it was built; all three times due to high winds gusting close to or over 70 miles per hour.

The bridge has also been closed for visits from dignitaries President Franklin D. Roosevelt and President Charles de Gaulle of France and also on its 50th and 75th Anniversaries.
