The structures delivered to the site include embedded pipes and cofferdam wall elements; they are being placed on the technological platform on the left bank. Later, their large-scale assembly will begin here. This technology will be used for the first time in Russian bridge construction. Floating cofferdams are temporary watertight frames necessary to create dry zones in the riverbed. They will be needed to build the central and two side pylons that hold the spans of the cable-stayed bridge over the river. The length of the two largest spans is 840 meters. To support such a large-scale structure, the height of the pylons will be from 194 to 284 meters.
Up to 250 heavy-duty trucks are involved in the transportation of metal structures. Delivery is carried out in several stages and includes the use of a winter road - a temporary crossing from the right to the left bank, accessible in winter. After the construction of the Lena Bridge, the need for this unsafe route will disappear. The bridge crossing will provide year-round land communication between the regions of Yakutia divided by the river.
The concession project for the construction of the Lena Bridge is unique not only for Russia, but also for the whole world. This is the first bridge of such a design and complexity that is being built in Arctic conditions. The investor and concessionaire is the VIS Group, the concession grantor is the Government of the Republic of Sakha (Yakutia).
60% of the metal structures of the cofferdams for the construction of the Lena Bridge are manufactured
In Tyumen, the StalMost plant continues to manufacture steel structures of the cofferdams needed for the construction of the pylons of the Lena Bridge in the riverbed. To date, over 2,650 tons of metal structures have been manufactured, which is about 60% of the total volume. A total of 4,521 tons of structures will be manufactured for the three riverbed pylons of the bridge. To date, 1,611 tons have been shipped from Tyumen, 682 of which are already being unloaded at the construction site in Yakutsk.The structures delivered to the site include embedded pipes and cofferdam wall elements; they are being placed on the technological platform on the left bank.
