The first snow has fallen in Yakutia, and nighttime temperatures are already dropping to -10°C. VIS Group is preparing the Lena River Bridge construction sites for the winter season; work, including operations within the river channel, will continue without interruption during this period.
The installation of bored piles continues inside the cofferdams for the bridge's central and right pylons. To date, 49 piles have been completed in the central cofferdam and 8 in the right one. This number is sufficient to ensure the stability of the massive metal structures during the spring ice drift.
An embankment serving as a service access road has been constructed, stretching from the right bank to the nearest cofferdam, in order to avoid interrupting work in the river channel during the winter. Nearly 240,000 m³ of sand were used for this purpose. Metal framework structures for an insulated enclosure are currently being assembled around the central cofferdam; this shelter will allow personnel and machinery to continue working during periods of extreme cold. Preparations for the winter season are also underway at the work sites located on both banks, with the construction of administrative and utility complexes, dormitories, canteens, and production workshops. Currently, VIS Group has over 500 people engaged in the work.
In total, 357 of the 920 piles required for the foundations of the bridge's 26 piers have already been completed across both banks and the riverbed. On the right bank, over 725,000 m³ of soil, which is over a quarter of the planned volume, have been placed for the future bridge approach road.
The Lena Bridge will be a unique facility on a global scale, the only one of its kind built in an Arctic zone with seasonal temperature fluctuations of 100°C, permafrost, and seismic activity. The combination of these natural factors, along with the river's complex hydrological regime, presents builders with challenges unprecedented in the history of bridge construction. This 4.6-kilometer, three-pylon cable-stayed bridge will, for the first time, enable year-round vehicular traffic between the parts of Yakutia separated by the Lena River. The new transport artery will span a total of 14.5 kilometers, linking the Lena and Kolyma federal highways with the Vilyuy highway, effectively connecting the eastern part of Russia with the coast of the Sea of Okhotsk.
This project, one of modern Russia's largest and most complex infrastructure undertakings, is being implemented under a concession agreement utilizing non-budgetary funding, which accounts for 47% of the construction-phase costs. Co-financing is provided by both federal and regional budgets. As the concessionaire, VIS Group is responsible for the non-budgetary share of capital expenditures, as well as the design, construction, and subsequent operation of the Lena Bridge through 2048. The Government of the Republic of Sakha (Yakutia) acts as the grantor.
