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.
- Total bridge length: 791,56 m
- Bridge layout: 33,6+4х77+110+154+132+33,6 m
- Number of span structures: 9
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.
- 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.
- August 2017 – installation afloat of the largest bridge span with a total weight of more than 1200 tons and a length of 154 meters.
- June 2018 – closure of the main span of the railway bridge over the Don River.
- January 2020 – installation of the inventory rails with a length of 12.5 meters on BMP slabs.
The construction project is planned to be completed in 2021.

At a length of 410 km, the Elegest–Kyzyl–Kuragino railway is the largest railway in the history of modern Russia: 120 km will run through the Tyva Republic and the remaining 290 km will go through Krasnoyarsk Krai. This railway line will be the first step in fully developing the Elegest deposit, with its unique coking coal reserves, and it will connect Tuva with the Trans-Siberian Railway.
Length: 410 km
Number of bridges: 127
Number of tunnels: 8
Total volume of freight traffic: 15 million t/year
