Golden Gate Bridge Facts For Kids

1. What is the Golden Gate Bridge

  • The Golden Gate Bridge is San Francisco’s icon landmark and marvel of modern engineering.
  • It is a suspension bridge that connects San Francisco Bay with the Pacific Ocean. The San Francisco Golden Gate Bridge spans over a 1.6 km (1 mile) wide strait which is known as the Golden Gate.

2. Why is it called the Golden Gate Bridge – Golden Gate Bridge Name

  • It is called the Golden Gate Bridge because it spans over a strait named Golden Gate Strait.
  • The Golden Gate Strait is 1.6 km (1 mile) narrow entrance between the San Francisco Bay and the Pacific Ocean.
  • In 1846, a US explorer named John C. Fremont named the strait as Golden Gate two years before the actual discovery of gold in California.

3. Why is the Golden Gate Bridge Important

  • Before the construction of Golden Gate Bridge and several other bridges, San Francisco was the largest American city that was still using ferry boats as mode of transportation. The need for a bridge increased with time and as population increased.
  • People used to get to Marin County from San Francisco through ferries. The available road way through the South Bay and up through the East Bay was very long and would take hours to reach Marin County.
  • When Golden Gate Bridge was constructed it solved this commute problem between the Marin County and San Francisco. As a result the Bay Area residents were not only able to commute easily to north up the cost but also their businesses flourished.

4. Why is the Golden Gate Bridge Famous

  • Historically, it was famous because it was the longest span bridge in the world till 1964 when New York City’s Verrazano Narrows Bridge was constructed. The New York City’s Verrazano Narrows Bridge is 60 feet longer than the Golden Gate Bridge.
  • Today it is the ninth-longest suspension bridge in the world.
  • It is well known for its extraordinary design and is recognized among the world’s famous landmark.
  • It has been a popular photography site and is very famous for its amazing view through the rising fog in the morning. Its orange color against the blue water and green Marin hills at the background along with the white fog makes it spectacular.
  • Unfortunately it is also known for the most suicide jumps from bridge in the world. Every year, more than 30 people jump to death from it.

5. Why is the Golden Gate Bridge a Landmark

  • A landmark is any natural, artificial, small structures or features of a place that:
    • stands out in its environment
    • can be seen from long distances
    • is used for navigation purposes
    • is local or national symbol
  • As per the above definition of landmark, the Golden Gate Bridge do stands our from its environment, is visible from long distances, is used for navigation purpose. So this is why Golden Gate Bridge is a landmark.

12. Golden Gate Bridge History – Why is the Golden Gate Bridge Historical

  • In 1849, after the Gold Rush boom, it was realized that the value of the land situated at the north of San Francisco Bay can be appreciated if a direct access to San Francisco city is provided.
  • A plan proposing a bridge spanning over the Golden Gate and connecting the San Francisco Peninsula with the Marin County was presented.
  • Though the idea of the bridge was presented in 1869 but it was not until 1916 when the actual proposal took place.
  • James Wilkin, who was an engineering student and working in San Francisco Bulletin, presented the idea of a 3000 feet long suspension bridge.
  • A $100 million was the estimated cost for such suspension bridge.
  • Michael M. O’Shaughnessy, who was San Francisco’s city engineer, started looking for engineers who could do it for a lower cost.
  • Joseph Strauss who was an engineer as well as a poet proposed that he can build such a bridge at a lower cost.
  • O’Shaughnessy and Strauss worked out a plan of building at least 4,000 feet long bridge within cost of $25-30 million.
  • The project faced many obstacles and litigation from different sources. Then the financing options got limited due the great depression in 1929. It was then in 1932, when Bank of America bought the entire project to help the economy.

13. How was the Golden Gate Bridge built – Golden Gate Bridge Construction

  • Anchorages

    The first step in building the Golden Gate Bridge was the construction of anchorages on both sides of the bridge. These anchorages were for tying down the main cables of the bridge. Concrete plants were setup on both sides of the Golden Gate as huge amount of concrete was required for the construction of anchorages. The anchorages were completed in 1936 and it took 3 years to complete them.

  • Towers

    Along the construction of anchorages, the construction of the two main towers was also started. At that time these towers were the highest towers to be ever built for a suspension bridge. The tower on the northern side was easy to build as it was located on the shore while the tower on the southern side was difficult to build as it was a thousand feet away from the shore inside the water. 30 feet long concrete fenders were erected on the sea bed to create an artificial island of concrete for the southern tower to stand on. Construction of the steel tower started after the completion of the artificial island.

  • Cables

    After the completion of the main tower and anchorages the work on main cables was started. The main cables had a diameter of 36 inches and were composed of 27,572 individual galvanized steel wires. The main cables were run over the top of both the towers for about 7,650 feet (2,332 meters) and then anchored at both ends of the bridge. 250 pairs of vertical suspender cables were used to hang the deck (on which the road runs). The total load on main cables (123,000 tons or 122,000,000 kg) is distributed evenly between the two towers.

  • Flexed Roadbed

    The roadbed was allowed to flex a little in the wind so that the force exerted by the wind can be transmitted to the towers. This procedure allowed a lighter and thinner deck which not only saved time and money but also made the bridge look more beautiful.

  • Safety Net

    A safety net was suspended under the bridge to catch workers in case they fell down while working. The bridge deck was about 250 feet high and any one falling down will not only get drown but will also hit the water at a speed of 75 miles per hour. This safety net saved a lot of lives during the bridge construction. Only once it was unable to save 10 people when a 5 ton work platform fell into it. The net was unable to hold the weight of the work platform for long and the workers fell into the water and got drowned.

  • Painting the Bridge

    After the construction of the bridge, the last step was to paint it. The International Orange color was selected. This color is not only aesthetically pleasant but also enhances its visibility in fog.

14. Who made the Golden Gate Bridge

  • Who designed the golden gate bridgeIrving Morrow

    • It was designed by the Architecture firm Strauss Engineering Corp.

15. Who owns the Golden Gate Bridge

  • The Golden Gate Bridge is owned by Golden Gate Bridge, Highway and Transportation District.
  • It is a special-purpose district located in the San Francisco Bay Area that owns, maintains and operates the following three regional transportation assets
    • Golden Gate Bridge
    • Golden Gate Transit

16. What kind of bridge is the Golden Gate Bridge

  • The Golden Gate Bridge is a suspension bridge.
  • A suspension bridge is the kind of bridge in which suspension cables and vertical suspenders are used to hold the deck (on which the road runs). Cables are suspended between the bridge towers and vertical suspender cables are used to hold the weight of the deck which hangs below them.
