The document provides details about the construction of the Golden Gate Bridge in San Francisco. It describes Joseph Strauss, the chief engineer for the project. Key events included Strauss presenting the proposal in 1919, approval being given in 1923, and construction beginning in 1929. Safety measures introduced during construction included hard hats and respirators. The bridge opened in 1937 after over 887,000 tons of material were used. It has since become an iconic landmark and engineering achievement.
