With the changes of The Times, every breakthrough in infrastructure construction is writing a new chapter in the development of human society. On February 1, 2024, the world's attention from Nandan to Tian-Xia-Lao Expressway Tian-Longtan Bridge was officially opened to traffic, marking the completion of the entire line of the expressway. The world's largest span reinforced skeleton concrete arch bridge, with its span of over 600 meters, has become a milestone in the history of arch bridge construction.

The completion and opening to traffic of the Tiane Longtan Bridge has not only written a new chapter in engineering technology, but also injected new vitality into regional economic development. In the past, it took about 1.5 hours to travel from Nandan County to Tian 'e County, but now, with the opening of the bridge, this time has been reduced to about 40 minutes. This has greatly improved the traffic between the two places and strengthened the economic ties and exchanges between the regions.

The completion of the whole line of the South-Tianshan Expressway will have a profound influence on promoting the regional economic development. It will speed up the flow of logistics and promote the prosperity of tourism, while also providing residents of the two places with a more convenient way to travel. In addition, the successful implementation of this project also demonstrates China's excellent strength and innovation in the field of infrastructure construction.

The opening of the Nantian Expressway is not only a victory for a bridge, but also the pride of China's infrastructure construction. It has provided a solid support for sustainable regional economic development and set a new benchmark for global infrastructure construction. Let us hope that more such projects will take root on a global scale and inject new impetus into the development of human society. Editor/Xu Shengpeng
