China News Service, Jiamusi, August 17 (Zhou Xiaozhou, reporter Shi Yifu) At 9:58 on the 17th, at the construction site of the Tongjiang China-Russia Heilongjiang Railway Bridge, the installation of the last set of track cleats for the Sino-Russian standard rail interface was completed, marking The first cross-river railway bridge between China and Russia, the Tongjiang China-Russia Heilongjiang Railway Bridge, has achieved track laying and connection, laying a solid foundation for the opening and operation of the entire bridge.
The newly built Tongjiang Sino-Russian Heilongjiang Railway Bridge is located between Tongjiang City, Heilongjiang Province, China and Ningskoye City, Russia. The total length of the bridge is 7,194 meters, the approach bridge is 4979 meters, and the main bridge is 2215 meters long, of which the main bridge in China is 1886. Meters, the main bridge in Russia is 329 meters long, with a designed operating speed of 100 kilometers per hour and an annual cargo delivery capacity of 21 million tons.

The bridge project started in February 2014. The main part of the Chinese section was completed in October 2018. In July 2019, the Chinese section completed all the acceptance procedures including static acceptance, dynamic acceptance, preliminary acceptance and safety assessment.
According to the China Railway Harbin Bureau Group Co., Ltd., the construction of the Tongjiang Sino-Russian Heilongjiang Railway Bridge has created many records.
It is the first cross-river railway bridge connecting China and Russia. It is the first internationally to use steel truss girder to lay a four-track track ballastless track slab construction program.

During the bridge design stage, Chinese and Russian engineers and technicians conducted in-depth and meticulous research on the bridge and track design standards of the two countries, and finally jointly determined the design plan to adopt the track gauge, which can adapt to the difference between the Chinese gauge of 1,435 mm and the Russian gauge of 1,520 mm. Standard gauge requirements.
During the construction period, the participating units overcome hard ice, frozen soil, sand inrush and other problems, and innovated anti-corrosion coating, high-bolt construction, and deep-water cofferdam anti-collision technology in high-cold areas, ensuring the smooth progress of the bridge construction.
The Tongjiang Sino-Russian Heilongjiang Railway Bridge connects to the three northeastern provinces of China in the south and radiates the whole of China. The addition of a railway transport channel between China and Russia will also open up a new Eurasian combined transport channel from West to Europe.
After the completion and opening to traffic, the railway transportation distance from Heilongjiang via Tongjiang to Moscow will be shortened by 809 kilometers compared with Suifenhe port, saving 10 hours of transportation time, which will greatly alleviate the transportation pressure of Manzhouli and Suifenhe railway ports, and effectively help the northeast region to be deeply integrated into the "Belt and Road" construction. It is of great significance to promote the high-quality development of Sino-Russian economic and trade.
