A bridge is a very important transport hub, connecting each area like a root canal connected to each site. There is a popular Chinese saying that to get rich first, we can see that people are already well aware of the importance of the road to economic development. China's reform and opening up nearly 40 years to create such an economic miracle, a great reason is to attach importance to the construction of transport, extending the transport artery leads to economic development in various regions.
Obviously, since 2008, China has invested heavily in the construction of high-speed railways as well as building generous bridges. This is due to the conditions of the mountainous rivers in our country, so the bridge plays a very important role. Before talking about the world-renowned bridge, we all know the San Francisco bridge, Tokyo Bay Bridge. The twists and turns, now the world-famous bridges are basically concentrated in our country, such as the Qiantang River Bridge, Hong Kong-Macao Bay Area Bridge, Qingdao Sea Bridge, etc., does not include the construction of the western mountain bridge.
These world famous bridges play an important role in the economic development of their respective regions. But to say the most breathtaking bridge, I think none other than the Humen Bridge. Humen Bridge is one of the top ten landmark in Guangdong, Humen East Weiyuan, west of Nansha, across the Pearl River Estuary, a total length of 15.78 kilometers, the eastern and western wings of communication in Guangdong. As the forefront of reform and opening up, Humen Bridge's role in economic development is self-evident.
Humen Bridge, China's first large suspension bridge, its main fairway span 888 meters, ranking the forefront of China, known as "the world's first cross." The main cable length of the bridge is 16.4 kilometers. Each main cable consists of 13,970 galvanized high-strength steel wires with a diameter of 5.2 mm. If the two main cables are drawn into a single steel cord, they can be circled around the earth.
Every evening, the bridge will be clogged with water and the bridge is 4.6 kilometers long. After spending about 40 yuan on one occasion, the average cost per kilometer is about 10 yuan. Many drivers complain that this is too expensive.
