Fast facts 

  • Blagoveshchensk-Heihe bridge is designed as a steel-reinforced concrete extradosed bridge. It looks similar to cable-stayed bridge, but unlike the latter, the cables of the extradosed provide longitudinal compression of cross sections of the spanproviding additional strength in the support zones, which allows to reduce the number of steel elements, the length of the cables, the height of the pylons, the weight of the beam and, consequently, to reduce construction costs. 
  • The bridge construction was carried out jointly by Russia and China. The meetings were held on the design and construction of the bridge with the participation of builders and engineers from both countries several times a year in order to avoid any discrepancies

Railway bridge across the Don River

at the 280th kilometer of Morozovskaya - Volgograd section of Privolzhskaya Railway Line 

The bridge will support traffic of freight trains weighing up to 12 thousand metric tons moving at a speed of up to 90 kilometers per hour. After the new bridge will be opened for traffic, the old bridge will be dismalted.

Fast facts 

One of the most difficult stages of bridge construction was the installation of support No. 8 between navigable fairways with a water depth of up to 20 m in the construction area. Due to the large depths, the construction of the support was carried out using a suspended bottom without sheet piling into the ground. The support is designed with a high pile grillage that is not supported by the river bottom. First, 22 bored piles with a diameter of 1500 mm were installed at the base of the support. Then a metal suspended bottom was submerged in the water to a depth of 13 m with the help of auxiliary structures, on which a metal box-shaped section was installed. Metal suspended bottom-the base for the backfill layer and the construction of the grillage. After the installation of the backfill layer, water was pumped out of the metal box-section member and the construction of the support was done in the usual way. 


Project timeline 

  • November 2011 – start of works. 
  • June 2013 – installation of the first 33.6 m long span structure on supports No. 9 and No. 10 on the left bank of the Don River.
