Construction of 3 bridges (Bugrinskogo / Olovozavodskogo) across the Ob in Novosibirsk

The final sliding of the last 83 meters of the third bridge spans (Olovozavodskogo) in Novosibirsk across the Ob completed, it can be seen in Live Scores construction of the bridge. The distance between the steel structure spans the shore and torque arch bridge after sliding of the order of 46 meters.

Olovozavodskogo sliding of the bridge was carried out using hydraulic equipment

The new symbol of the capital of Siberia — the third city will arched bridge. Arch has a shape resembling a bow, one of the characters itoricheskih Siberia. The same form — is the emblem of the city of Novosibirsk and the largest opera house in the Urals.

Bugrinsky bridge is unique — it is the only one in Russia has a mesh arch and an observation deck on top of it. Here, at the same time and without problems diverge 2 river boat.


The parameters of the bridge

  • materials: concrete, steel and iron
  • arch span length of 380 m, width 26 m, height of 70 m (the highest in Russia!)
  • boom lift combined with a tightening of the arch 83 m
  • number of supports 30 pc
  • clearances navigable bay width 140 and 100 m, height 15 m
  • total length of the bridge about 5480 m
  • the main highway — 6 lanes, throughput sposobonost 7180 cars / hour
  • withstand wind pressure of 38 kg per square meter. m
  • footbridges are equipped with ramps
  • storm water heating and individual sewage treatment
  • cost of the bridge 14805462000 p.

All contractors involved in the construction of the bridge Olovozavodskogo throughout the year provided a very strong performance. Changes in the urban appearance is minimal.

Just being built:

  • interchanges with overpasses Novtutina, Kirov, elective, and at the intersection with the departure from Novosibirsk on M52 "Chuiski."
  • overpass over railroad Altai.


The need to build

Novosibirsk — the crossroads of water, air and rail links. The center of the cultural life of the Urals. From 2006 to 2028 the gross regional product will grow by 4.5 times. The number of inhabitants increased to 1.6 million. Demand for travel will grow by almost 40%. The number of cars will increase to 450 units. per 1000 inhabitants. In terms of five new bridges across the river Ob. Formation of around 50 km of the capital of Siberia. Area roads first category. Plans are implemented.

But as long as the density of the road network is almost 3 times less than normative. Not only through the city roads. On those that are, many intersections in the same level with smaller streets, tram lines and railroads. Therefore, at the level of the Russian government, and the administration of Novosibirsk city administration decided in principle on the construction of a new bridge over the river Ob. October Dimitrov and bridges across the Ob River in 2011 working at full capacity — to 80 thousand cars a day in both directions.

Bugrinsky bridge will provide Novosibirsk unloading of existing bridges and liberate the city center. By 2025, the direct net benefits to transit carriers amount to 1.5 billion rubles.

The general plan of development of Novosibirsk Bugrinsky bridge structure is in the south-west transit — high-speed thoroughfare of continuous movement. It will link the federal highway M52, and M51 Chuiski "Baikal". Construction of the bridge in olozavodskom alignment faster and more efficient displays all of the traffic flows from the central city of Russia on the one hand — with Mongolia, Kazakhstan, Altai and the Kuzbass — on the other. Previously, all the traffic going through Novosibirsk through the first and second municipal bridges. The need to build a new bridge has ripened for 15 years ago.

The shortest route to the left bank of the Ob River and the railway station Jansky — is unloading the city's main thoroughfares, profitable gruzoobmen river port, rail and road transport. There will also loads of industrial and logistics park and the airport Tolmachevo. The average distance of transit will be reduced by 8.5 km. According to forecasts Bugrinsky bridge will take 35% of traffic flows through the Ob. More than 7,000 vehicles per hour. Will begin development of surrounding areas, the development of new urban complexes. For example, a key kamyshenskogo plateau — a second downtown Novosibirsk.

The complexity of building

Olovozavodskoy target for the construction of the river — not a gift. All objects in a dense building. Highway crosses the railroad Ob Bugrinskuyu grove. Along the way on the left bank floodplain of Tula. Right Bank — the mouth of the Fast and Pluschikha. Hills with gullies in the streets of Kirov and the Electoral

But the main problem in geology. Under the bed here converge on 3 different formation time and the conditions of the tectonic structure. Archives and geophysics research project studied the Siberian Institute of Geology, Russian Academy of Sciences. In the central part of the fault zone channel geophysical studies found strong rocks of the roof down to a depth of 90 m Therefore, to further design option is selected with an arched spans a length of 380 meters, avoiding the construction of support in the mainstream. Net Triomphe — crisscross design with flexible suspension. Figure suspension is determined by strict rules, with four points, which allows for the most cost-section belts and the roadway. Sami suspension made by monostrendovoy technology and represent a bundle of ropes made of galvanized wire. Each Strand is pressed at the plant in a plastic shell, filling the space with special grease. Thus, a cell with a lifetime exceeding 70 years and do not require special maintenance.

Construction Stages

The line will be introduced in two steps. In the first phase, a period of 63 months ending in the fourth quarter of 2013, construction of the bridge will be done with ramps and entrances Novotutino and Bolshevik.

At the second stage of bridge builders will complete the viaduct on the Bolshevik, erected over the railway overpass Altai direction, arrange congresses on Kirovai will join the road network. The project began the second stage in the 1st quarter of 2014 — ending in the fourth quarter of 2015 but, thanks to anticipatory financing already created serious for the future.
