Volga bridge in Dubna commissioned

03/12/18  

Mostotrest completed construction of a bridge over the Volga River in Dubna at the end of November 2018, two months ahead of schedule. The standard term for construction of such facilities is 48 months, while the Mostotrest contract period was set at 25 months.

On 29 November 2018, the new bridge was opened to both automobile and pedestrian traffic.

The opening ceremony was attended by Moscow Region Governor Andrei Vorobyov, Presidential Plenipotentiary Envoy to the Central Federal District Igor Shchegolev, State Duma Deputy Irina Rodnina, and Head of the Dubna City District Maxim Danilov. The bridge builders were represented by Mostotrest CEO Vladimir Vlasov, Director of Mostootryad-90 Andrei Afanasyev and Project Manager Alexander Krymsky.

Igor Shchegolev: “The bridge is unique both in terms of its total length and superstructure. It is very important that new projects such as this improve territorial links. It has been wonderful to work with professionals capable of delivering top quality work in a short time. The city has been waiting for this bridge for several decades.”

Andrei Vorobyov: УThe builders showed a high degree of professionalism and delivered the project ahead of schedule. This is a wonderful and memorable event... We are very grateful to Mostotrest for their well-coordinated, rapid and highly professional work. You are a great company and we intend to continue working with you in the future."

The standard construction period for this type of facility is 48 months, while the Mostotrest contract period was set at 25 months. The bridge was built in the shortest possible time: the builders deployed on the construction site in December 2016, and the bridge was opened to traffic as early as at the end of November 2018, two months ahead of schedule.

Delivery of such construction volumes in a short time – 2x faster than the standard - was made possible thanks to rapid deployment on the site and effective construction management. Immediately after the conclusion of the contract, work began on drilling piles; 10 drilling rigs worked on pile foundations (simultaneously for several pillars); during the peak months, more than 1,000 people and over 100 units of equipment were deployed on the construction site. Three plants simultaneously supplied steel structures for the bridge spans, and the spans were also installed simultaneously on the left- and right-bank elevated approaches and the bridge itself.

The distance between the bridge’s channel pillars is 168 meters, making it a unique structure. Such length of channel passage was required to preserve full-fledged navigation.

As part of the project, Mostotrest built a four-lane bridge crossing with a total length of 1,940 meters and the bridge length of 485 meters. The bridge traffic capacity is 4,420 cars per hour and the design speed is 80 kmh.

During the bridge construction Mostotrest mounted a total of 15 thousand tons of span steel structures and 10 thousand tons of auxiliary structures; laid 50 thousand cubic meters of concrete; made more than four hundred drilling piles with a diameter of 1.5 meters and a depth of 38 meters; and ran 4 thousand grooves.

As part of the project, Mostotrest built a three-lane roundabout junction between Bogolyubov Avenue and Vernov Street, as well as four exit ramps, sidewalks and pedestrian crossings.

It is important to highlight professionalism and effective workflow organization and management at Mostootryad-90, which once again flawlessly delivered on their task, using all their expertise, strong skills and competences.

The new bridge across the Volga in Dubna established a reliable transport link between the two parts of the city divided by the river. The Dubna Free Economic Area is located on the left bank of the Volga, and its connection with other cities of the Moscow Region and with the City of Moscow will now significantly improve.

Previously, the only crossing between the tow parts of Dubna was a narrow road over the hydroelectric dam, built in 1937. For heavy vehicles, the only way to cross the Volga was a bridge in the town of Kimry, Tver region, located 25 km from Dubna.
