Слайд 4 Before the bridge was built, the

only practical short route between San Francisco and what is now Marin County was by boat across a section of San Francisco Bay. Ferry service began as early as 1820, with regularly scheduled service beginning in the 1840s for purposes of transporting water to San Francisco.
Many wanted to build a bridge to connect San Francisco to Marin County. San Francisco was the largest American city still served primarily by ferry boats. Because it did not have a permanent link with communities around the bay, the city’s growth rate was below the national average. Many experts said that a bridge couldn’t be built across the 6,700 ft (2,042 m) strait. It had strong, swirling tides and currents, with water 500 ft (150 m) in depth at the center of the channel, and frequent strong winds. Experts said that ferocious winds and blinding fogs would prevent construction and operation.

The project cost more than $35 million.
Joseph Strauss, was an ambitious but dreamy engineer and poet who had, for his graduate thesis, designed a 55-mile (89 km) long railroad bridge across the Bering Strait. Strauss remained head of the project, overseeing day-to-day construction and making some groundbreaking contributions.
The project was finished by April 1937, $1.3 million under budget.
A statue of Strauss was moved in 1955 to a site near the bridge.

Слайд 6 The center span was the longest

among suspension bridges until 1964 when the Verrazano-Narrows Bridge was erected between the boroughs of Staten Island and Brooklyn in New York City, surpassing the Golden Gate Bridge by 60 feet (18 m). The Golden Gate Bridge also had the world's tallest suspension towers at the time of construction and retained that record until more recently. In 1957, Michigan's Mackinac Bridge surpassed the Golden Gate Bridge's total length to become the world's longest two-tower suspension bridge in total length between anchorages, but the Mackinac Bridge has a shorter suspended span (between towers) compared to the Golden Gate Bridge.
The weight of the roadway is hung from two cables that pass through the two main towers and are fixed in concrete at each end. Each cable is made of 27,572 strands of wire. There are 80,000 miles (129,000 km) of wire in the main cables. The bridge has approximately 1,200,000 total rivets.
