The Golden Gate Bridge is a suspension bridge spanning on the Golden Gate, the one-mile-wide (1.6km) strait connecting San Francisco Bay and the Pacific Ocean.
It was initially designed by engineer Joseph Strauss in 1917.
At the time of its opening in 1937, it was both the longest and the tallest suspension bridge in the world, with a main span of 4,200 feet (1,280 m) and a total height of 746 feet (227 m).

GOLDEN GATE BRIDGE'S HISTORY

If you have a couple of minutes, I recommend watching this stunning drone video of Golden Gate Bridge. It isn't long, but definitely worth watching.

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. The trip from the San Francisco Ferry Building took 27 minutes. Many wanted to build a bridge to connect San Francisco to Marin County. A fair amount of experts said that a bridge could not be built across the 6,700-foot (2,000-metre) strait, which had strong, swirling tides and currents, with water 372 ft (113 m) deep at the center of the channel, and frequent strong winds. They claimed that ferocious winds and blinding fogs would prevent construction and operation.

Fact about the bridge

Golden Gate Bridge's official site

The Golden Gate Bridge is the most used suicide site in the world. 
The deck is about 245 feet (75 m) above the water. After a fall of four seconds, jumpers hit the water at around 75 mph (120 km/h; 30 m/s). Most die from impact trauma. About 5% survive the initial impact but generally drown or die of hypothermia in the cold water. After years of debate and an estimated more than 1,500 deaths, suicide barriers, consisting of a stainless steel net extending 20 feet from the bridge and supported by structural steel 20 feet under the walkway, began to be installed in April 2017. Construction was first estimated to take approximately four years at a cost of over $200 million.

Miniature model of the bridge

This is the video me and my friend have based on while making the miniature model.

This is a video of the model we made. It took us a lot of time and effort, but in our opinion, it was worth it.
