The result of investing a huge amount of funds, consuming a lot of manpower, and meticulously designed drawings... all of these combined should have been a magnificent building like a spectacle, but even if it were not, it would have to be a beautiful and sturdy high-rise building.

However, the ultimate harvest wasThe Suspension bridge that was blown down by the wind, the cable-stayed bridge that was crushed by vehicles, and the "future city" that only exists in the plan.

What exactly went wrong?

Tacoma Narrows Bridge

On July 1, 1940, the Tacoma Narrows Bridge located in Washington State was officially opened to traffic.

This is undoubtedly good news that excites the local people. You should know that the desire of the local people to build a bridge here can even be traced back to forty or fifty years ago. It has only been postponed until now due to various reasons.

This is because two famous engineers had disagreements when designing the construction plan for the bridge.

However, another engineer, Leon, has a completely different view. He believes that his theory can be fully adopted, using narrower steel beams as support to ensure the durability of the bridge while not only being aesthetically pleasing but also saving money.

The result is self-evident, Leon won the design competition.Three years later, the world's third longest Suspension bridge was officially completed.

Is this reasonable? Obviously unreasonable!

This situation did not occur after the bridge was opened to traffic, but rather had early indications during the construction processHowever, the workers at that time did not care about it.

With this idea in mind, many workers even deliberately chew lemons to prevent themselves from getting seasick.

Although the workers are very confident about the safety of the bridge, the local residents who are not sure where they are can rest assured. Not to mention anything else, when encountering windy weather, walking on the bridge is barely a problem. How can I drive the car? Isn't it certain that there will be a car accident?

To everyone's surprise, the fluctuation of the Tacoma Bridge became increasingly large, forming turbulent waves in the air. With a loud bang,Everyone was dumbfounded to see this $10 million Suspension bridge suddenly disintegrate in midair.

The bridge has collapsed! Under everyone's gaze, it was blown down by the wind!

Fortunately, there was only one car driving on the bridge at that time, and the owner was also sensitive enough to abandon the car and escape after noticing something was wrong. This serious collapse accident did not result in death.
