The traditions of "Bridge No. 6" were laid during the Great Patriotic War, when, as part of the army, the bridge trains quickly restored bridges and crossings under continuous enemy fire.

On August 31 of 1945 of the year, for the construction of destroyed road-bridge structures and the construction of new ones, the Bridge Restoration Department of the Nevsky-Volkhov basin was created on the basis of bridge trains in Leningrad. For the first post-war five-year plan, the Administration built and reconstructed 138 bridges with a total length of more than 9 kilometers.


After separation from the Ministry of Railways of transport builders and the formation of the Ministry of Transport Construction, the Office received a new name - Trust Bridge Moststroy No. 6.

In the same year, specialists of the trust commissioned the first in the Soviet Union four-way railway overpass through Moskovsky Prospekt in Leningrad with spans 52 m long.


The first reinforced concrete river bridge was erected in Arkhangelsk. A bridge crossing over the Kuznechikha River with a length of 360 meters was built during 3 years. Mostostroy No. 6 was one of the first in the country to master work with spans of this length.

In the same year, specialists of the trust commissioned the first in the Soviet Union four-way railway overpass through Moskovsky Prospekt in Leningrad with spans 52 m long.


A crossing was erected by a trust across the Oyat River on the road connecting Leningrad and Murmansk. During the construction of the bridge, for the first time in our country, the technology of box-type prefabricated reinforced concrete spans of a frame-console system with dry joints between blocks was applied. Later this experience formed the basis for the creation of a number of large bridge structures.

From 1960 to 1978, the trust built 13 similar bridges, including the A. Nevsky Bridge in Leningrad, two bridges across the Velikaya River in Pskov, bridges across the Volga, Sukhona, Vetluga, Mstu and Shosh.


The first bridge over the Northern Dvina was built in Arkhangelsk. During the construction of this movable drawbridge combined with a length of more than 1 km, for the first time in Russian practice, building supports were built on reinforced concrete shells with a diameter of 4 and 6m depth to 50 m at a water level of more than 25m. Metal spans were mounted in a full canopy with a console 176m in length and 2500t in weight using a prestressed spreader.


The longest crossing in St. Petersburg, the Alexander Nevsky Bridge, was put into operation.

The construction, built in 1965 year, had a record for its time channel span of 126 meters. The length of the bridge, along with overpasses and ramps, is 906 meters, width - 35 meters. For the first time, the original principle was applied in the construction of the bridge crossing: steel cables of cable-stayed reinforcement were placed in the hollow tunnels of the longitudinal beams, which, with the inevitable deformation of the crossing, could be pulled up or released to the specified stresses.


A complete reconstruction of the Foundry Bridge in Leningrad. Over the 2 year, the metal structures of the structure were completely replaced, the width of the bridge bed was increased by 10 meters, the turning draw span was replaced by the opening 55 meter span and moved to a deeper place. An adjustable span weighing 3225 tons began to lift hydraulically in just two minutes.


In Cherepovets, the Oktyabrsky Bridge across the Sheksna River is open for traffic, which became the first cable-stayed bridge in Russia. The asymmetric, single-pylon six-lane bridge has a length of about 780 m, the height of the structure is 85 m, and the total length of the cable stay is 16 km.

A capsule with a plate was laid in one of the bridge supports - a message to the descendants: “Today, on the 22 of April 1970 of the year, on the day of the 100 anniversary of the birth of V.I. Lenin, the team of V.I. Batishchev of the bridge train No. 809 of the Leningrad trust“ Mostostroy No. 6 ", having scored the first pile, proceeded to the construction of a bridge over the Sheksna River in the city of Cherepovets."


By the beginning of the 80's, Mostostroy No. 6 became the largest organization in the country specializing in the construction of road and railway bridges, overpasses, overpasses, tunnels and moorings. In 1981, the company was awarded the highest award of the Soviet era for its activities - the Order of Lenin. In the same year, the Ladoga drawbridge across the Neva was put into operation.

The Ladoga bridge connects the Neva coast in the place where in January 1943 of the year there was a unique tree-ice crossing for T-34 tanks. On the left bank of the bridge’s abode there is the Museum-Diorama “Breakthrough of the Siege of Leningrad” opened in 1983. A monument was installed near the bridge - the T-34 tank. The bridge, diorama and monument are part of the Breakthrough memorial complex.


In July of the 1983 of the year, the USSR’s first submarine road and pedestrian Cannoner tunnel, constructed using the lowering section method, began operating.

All work was carried out without stopping the movement of large vessels along the Sea Canal of the Leningrad Trade Port and trains in the vicinity of the nearby railway station.


Since 1986 of the year, Mostostroy No. 6 took part in the construction of railway bridges. Obskaya-Bovanenkovo ​​on the Yamal Peninsula to the Bovanenkovo ​​gas condensate field.

Specialists of the trust in the conditions of permafrost built 7 of capital and temporary railway and combined bridges.


A pedestrian bridge was built in Novgorod, which has become one of the symbols of the city.

A three-span continuous beam bridge was constructed with curved (arched) outlines of the lower zone. The total weight of the metal structure was 800 tons. According to technical specifications, about 8000 people can simultaneously be on the bridge.


1980 completed the construction of one of Europe’s largest automobile bridge crossings - the Krasnoflotsky bridge across the Northern Dvina in Arkhangelsk. The length of the bridge, including the left-bank overpass and bridges across the left and right branches of the Northern Dvina, was 3950m.


Reconstruction of the Volodarsky bridge in St. Petersburg. During the work, 800-ton 125-meter spans were installed on the right-bank and left-bank abutments, which were then connected by an 57-meter adjustable span. To ensure communication between the districts of the city, a temporary bus and pedestrian bridge was built during the reconstruction period.

In the same year, experts of the trust erected an overhead extension for the tram congress near the bridge.


In 1993, the trust was transformed into the Open Joint-Stock Company Bridge Construction Trust No.6. Since that time, having fully retained its personnel and production potential, the company has been actively involved in the formation of new market relations, expanding the directions and geography of its activities.

A bridge was built across the Sukhona River in the village of Nyuksenitsa, Vologda Oblast. At the time of construction, it was the first bridge in Russia with a maximum span of 105m, pulled without the use of temporary supports, using a universal rigid spreel.


The Bolsheokhtinsky bridge was reconstructed in St. Petersburg. At the same time, more than 3000 steel structures were installed, more than 48000 square meters of asphalt and about 10000 cubic meters of concrete were laid.

In 1997, in the All-Russian competition for the best construction organization, Mostostroy No. 6 was awarded a diploma of the 1st degree, and the company took the 4 place in the rating of the best construction and installation organizations in Russia.


The reconstructed bridge over the Saimaa Canal in Vyborg was commissioned.

During the work, the supports of the existing structure were left without restructuring, and all the spans were replaced. Reinforced concrete side spans were replaced with metal, the adjustable span was disassembled and replaced with a metal non-adjustable span, similar to the side spans of the bridge.


The Pavlovsky bridge over the Saimaa Canal was built on the bypass of Vyborg. A bridge with a length of 434 m with spans of up to 100m and a height of supports of up to 30 m for passage of ships was built in 14 months.

Pavlovsky bridge is included primarily in the construction of the Vyborg bypass. The 6,6 km bypass section took place in difficult geological conditions. Numerous boulders, the diameter of which exceeded three meters, and granite rock, through which the route was conducted, required blasting.


The reconstruction of the Krasnoluga bridge in Moscow has been completed. The structure was erected on the supports of a bridge built at the beginning of the 20 century during the construction of the Moscow Ring Railway. Reconstruction works were carried out in a short time, in the conditions of dense urban development, with many communications and heavy traffic. The length of the bridge is 135 meters, weight - 1400 tons.

The bridge of Alexander Nevsky in St. Petersburg was reconstructed.


A transport interchange was built at the intersection of the St. Petersburg ring road with the railway and Primorsky highway in the vicinity of Gorskaya station.
