The first pile was concreted at the construction site of the drawbridge as part of the SCHMSD

Specialists of JSC Roads and Bridges of the National Project of Construction at the site of the future drawbridge across the Neva River as part of the construction of the Latitudinal high-speed Highway completed the concreting of the first drilling pile and began laying the foundation. This is the starting point, but the most important stage in creating supports for the most difficult section of the highway.
"The path to a unique structure begins with the first pile – the second drawbridge across the Neva River in forty years with a record 61-meter-long wing and fast wiring. The ferry as part of the SCHMSD has a unique design and is designed in balance with the historical appearance of St. Petersburg. It will preserve the panorama of the neighboring Finnish Railway Bridge, an object of cultural heritage," said Governor Alexander Beglov.
The first pile with a diameter of 1,500 mm and a length of 31.1 meters is immersed in the base of the future channel support. The technology is standard for such structures, but requires high precision: after drilling the well, a reinforcement frame was installed in it and filled with concrete. Such a foundation will ensure maximum load-bearing capacity even on difficult soils.
As Mikhail Fokin, Director of Construction at the Northern Capital Latitudinal Highway LLC, a concessionaire company, noted, a huge amount of work remains to be done to build the bridge. There are more than 1,200 drilling piles, 160,000 cubic meters of concrete, and 16,000 tons of metal structures ahead.
"The first pile is not just a technical milestone, but the moment when stage 4.1 begins to take shape," said Mikhail Fokin.
The bridge over the Neva River is the central element of the fourth stage of the CMMSD, which is considered the most intense in terms of engineering complexity. The total length of stage 4.1 exceeds 5 kilometers (3.4 km on the right and 4.5 km on the left).
The 462.9-meter-long bridge crossing in the alignment of Fayansovaya and Zolnaya streets will be supported by 11 pillars, six of which will stand directly in the riverbed of the Neva River. At the same time, the bridge is designed to be low, with a mark of about 10 meters above the ground, so as not to obscure the panorama and not disrupt the view of the Finnish Railway Bridge.
"The work is being carried out in conditions of cramped urban development – cultural heritage sites and transport infrastructure are nearby. Here, the experience gained over two years at the Bolshoy Smolensky Bridge and adjacent interchanges will be useful to us – logistics have been fine-tuned, technologies have been developed. We will do everything in our power to complete all the work on time and with the best quality," said Alexander Ilyin, Director of the branch of JSC Roads and Bridges of Mostootryada–99.
It should be recalled that on June 5, within the framework of the St. Petersburg International Economic Forum, a commemorative stone was laid to mark the start of construction of Stage 4.1, with the participation of Andrey Kostin, President and Chairman of the Management Board of VTB Bank, and Alexey Krapivin, CEO of NPS Group JSC.
