Golden Gate Bridge is one of the world famous bridges and a miracle of modern bridge engineering. The bridge, which lasted four years and over 100,000 tons of steel and cost 35.5 million US dollars, was designed by Josef Strauss (1870-1938), a bridge engineer, standing on the 1,900-meter Golden Gate Strait of the Governor of California. The Red Bridge spans under the blue sky, on the green hills, with exotic flowers and plants around it, and boats swinging in the water on the blue waves. It is one of my favorite attractions during my 19-day trip. Happy family.
