When humanity decided to connect two places by a bridge.
It often means overcoming a range of technical and natural challenges.
The builders of the Shenzhong Corridor seem to be particularly interested, building a bridge and a composite megaproject of bridges, islands, tunnels and underwater interconnections, setting 10 records in the world.
These include the world's world's largest full-offshore steel box girder suspension bridge and the world's longest two-way eight-lane subsea immersed tunnel, which sounds enough to excite any engineer.
The project was fraught with challenges at every step of the way, from initial planning to final commissioning.
How engineers lay huge immersed tubes in the deep sea under enormous water pressure or erect huge steel beams in a changing marine environment.
These operations require extreme precision and innovation, and each step can be a technological or logistical breakthrough.
The Shenzhen-Zhongshan Corridor is designed not only to connect the two places, but also to facilitate smooth transportation and the development of the regional economy.
The opening of the corridor has greatly improved the traffic situation in Zhongshan, Shenzhen and even Guangzhou and Nansha, and also made economic and cultural exchanges between these cities more frequent. The bridge is not just a road, it is a powerful tool for regional integration.
Such a huge project also comes with a corresponding cost.
The vehicle toll fee for the Shenzhen-Zhongshan Corridor is set at 66 yuan per standard trip, which is considered by many to be a reasonable payment for this convenience. At the same time, the charges reflect the huge construction and maintenance costs of the bridge.
In addition to self-driving, the opening of the Shenzhen-Zhongshan Corridor has also opened cross-city bus services, including two lines: Expo Center - Qianhaiwan Metro Station and Cuiheng New District - Qianhaiwan Subway Station.
This provides convenience for citizens who do not have a car, and it is also an environmentally friendly way to get around.
In addition, the Shenzhen-Zhongshan Airport and 24-hour shuttle bus services also provide users with more flexible options.
With the help of the Shenzhen-Zhongshan Corridor, not only Zhongshan and Shenzhen, but also the entire Pearl River Delta is quietly changing.
The bridge is not only a means of transportation between the two places, but also a bridge to promote social progress and technological development.
Such spectacular projects have made our lives more convenient, and we have been amazed by the wisdom and courage of human beings.
