On September 25, 2024, the construction of North China High speed Railway will usher in an important milestone. The Yongxing Hulan River Bridge in the Harbin-Yichun High-speed Railway project has successfully closed its continuous beams. This feat not only means that the longest and most technically challenging beam erecting channel on the whole line has been unblocked, but also lays a solid foundation for the subsequent construction of high-speed railway bridges, greatly promoting the progress of the entire project.

Yongxing Hulan River Bridge is located in the Harbin-Yichun High-speed Railway Tieli section, with a total length of 16709m, which is one of the most technically difficult construction projects along the line. The construction unit strictly controlled key processes such as basket walking, steel bar installation, and concrete pouring, overcoming the impact of extremely cold temperatures in Northeast China and successfully achieving closure.

Harbin-Yichun High-speed Railway is an extension of the Beijing Harbin Beijing Hong Kong Macao channel of China's "eight vertical and eight horizontal" high-speed railway network. It is the highest latitude high-speed railway under construction in China and the first high-speed railway crossing the island like permafrost area for many years. After the whole line is completed and opened to traffic, the travel time of passenger trains from Harbin to Yichun will be shortened from about 7 hours to about 2 hours, forming a "one hour, two hour" traffic circle centered on Harbin, and continuing to inject new vitality into local economic development and revitalization of the Northeast.
