VIS Group is actively working on the pile foundations for the pylons of the cable-stayed Lena Bridge, currently under construction in the Republic of Sakha (Yakutia). Work conditions within the riverbed have been established using the two previously installed cofferdams. Drilling rigs are operating inside both structures, and 13 bored piles have been completed to date.
The piles – measuring 1.5 meters in diameter and ranging from 27 to 40 meters in length – will ensure the secure anchoring of the cofferdams and serve as the foundation for the bridge's pylons. A total of 208 such bored piles will be installed in the central cofferdam, and 102 in the side cofferdam.
On the left bank, the installation of the perimeter blocks for the Pier 5 body is underway, with the work nearly 40% complete. On the right bank, the pile foundation for Pier 15 is fully finished, and the foundations for Piers 14, 17, and 26 are nearing completion. In total, 301 out of 920 piles have already been installed for the piers supporting the approach roads and the bridge itself. Embankment construction towards the Lena federal highway is in progress, with over 655,000 m³ of soil already laid. Over 500 personnel and 70 units of machinery are engaged in the bridge construction on both banks.
VIS Group is implementing the project under a concession agreement, a move that allowed to break the long-standing deadlock in 2019. Over the course of several years, design documentation was developed for what is set to be one of the world's most complex bridges – a project utilizing floating cofferdams, a technology previously unused in Russian bridge construction.
The Lena Bridge will drive economic and social development in Yakutia – Russia's largest federal subject – and provide a crucial missing link in the logistics chain connecting the country's central regions to the shores of the Sea of Okhotsk. Eventually, the bridge will also become part of the Mohe–Naiba transport corridor linking China to the Russian Arctic. The project is being implemented under the direct instruction of the President of Russia and is included in the “Infrastructure for Life” national project.
