Almost as soon as I heard about building bridges, I saw "a flying bridge"!

When building bridges, all kinds of machines are controlled by computers, requiring almost no human labor.

Nowadays, the reason why the cost of building bridges is high is not because of the length of the bridge but because of the height of the bridge.

...The project for the approach bridge is often larger than the project for the main bridge over the water.

Of course, the height should not differ too much to avoid driving difficulties.

This kind of pocket bridge may be made of a kind of plastic that is extremely light, soft, and extremely strong...

Such a beamless bridge should be regarded as the most progressive bridge!

The full text has 13 natural paragraphs, which can be divided into two parts:

Part 1 (paragraphs 1-2): Describe the importance and basic structure of the bridge.

Part 2 (paragraphs 3-13): Describe the long-term view of the bridge in detail.

Part 2, first level (paragraphs 3-4): Re-emphasize the importance of bridges.

Second level (sections 5-8): With the application of technology and new materials, bridges in the future will be built faster, lower, cheaper, more beautiful, and more convenient.

The third layer (paragraphs 9-13): breaks through the structure and shape of the existing bridge, and makes a bolder vision for the future bridge.
