Bamtonnelstroy-Most Group of Companies installs a pipeline under the riverbed of the Pregolya River


The first pipeline string has been laid by now

Another work stage of force main sewer pipelines installation by underground horizontal directional drilling under the riverbed has started within the construction of a road bridge over the Pregolya River in Kaliningrad.

Specialists of Bamtonnelstroy-Most Group of Companies are carrying out works at a depth of 14 meters using a special machinery. Replacement of pipelines is carried out in a densely built-up urban area without putting out of operation the existing networks.

“Within the new road bridge construction area, there are a lot of utility lines of different purpose that are to be reconstructed. It will allow to replace the existing equipment with a new one that has a longer service life,” General Director of SK Mostotrest LLC (a member of Bamtonnelstroy-Most Group of Companies) Evgeny Nadtochy said.

The construction of a road bridge over the Pregolya River will ensure traffic movement along the most popular routes from north to south in the western part of the city: it will connect urban areas with each other and with a railway station, as well as industrial zones of Kaliningrad with a port. The bridge will provide the shortest route between the A194 Kaliningrad – Ladushkin – Mamonovo – Polskaya Granitsa, A193 Kaliningrad – Pereslavskoye – Svetlogorsk and A192 Kaliningrad – Primorsk – Baltiysk highways.

Multilevel transport interchanges will be built at the approaches to the road bridge. The U-turn loop will be located on General Butkov Street.

The 386.7-meter-long road bridge has eight piers and three continuous spans. The central span will be navigable and it will be made of a vertically-lifting all-metal simple-span beam. The vertical lift mechanism of the superstructure will be located in the towers of the bridge.
