Our story of reading began long ago. From an early age, and if to be ...
Bugrinsky Bridge is the third road bridge under construction in Novosibirsk across the Ob River. The structure of the structure is atypical: the channel crossing is held by a semicircular arch. Over the 120 years of Novosibirsk's existence, not many objects have been built that have formed the recognizable silhouette of the city. The Bugrinsky bridge is undoubtedly one of them. On April 11, 2014, the final stage of sliding the arch vault took place: two spans from different banks closed at a height of more than 90 meters.
The bridge is an important part of the promising South-West Bypass highway.
The highway, 20 km long, will connect federal highways M-51 and M-52.
The total length of the bridge, including interchanges, will be 5480 meters.
The main structural element of the bridge is the channel span across the Ob, which is supported by a metal arch on flexible cables.
The arch is 380 meters long and 70 meters high!
This will be the largest arch span in Russia and the CIS.
It is necessary in order to close the geological fault that runs along the bottom of the Ob and falls into the zone of the bridge construction.
Construction work is being carried out by the general contractor Sibmost OJSC.
Six lanes (three in each direction) of the new bridge must provide a throughput of at least 4,800 vehicles per hour.
In total, 6 temporary supports were built in the river bed.
The highest temporary supports are # 5 and # 6.
15 meters height of the navigable span and 70 meters height of the arch.
During the construction of the bridge, metal structures from factories from Kurgan and Ulan-Ude are used.
Building berth for assembling and sliding the arch semi-arches (on support No. 6 - building berth No. 2, on support No. 5 - building berth No. 1)
The method of vertical sliding of the arch vaults along the contour at an angle of 45 degrees, used in the construction of the Bugrinsky Bridge, is used for the first time in the world.
Sliding device (hydraulic jacks)
The jack can move the beam two meters at a time.
The speed with which the jacks push the multi-ton tightening of the bridge arch is about 10 cm per minute.
In order to reduce the friction of the arch against the temporary support, prefabricated plywood sleds ("carriages") are used, which are placed on the sliding sheet as they slide.
The builders, placed on the supports, make sure that these "carriages" are replaced with new ones in time.
To prevent the arch from sliding back under its own weight, three long "rods" - dividags are used.
They work as insurance - after / before installation, the entire half-vault hangs on them.
On one side they are attached to the slipway, on the other from below to the beam (there is a special stop there),
during sliding, installers tighten the nuts, thereby taking out the slack.
After sliding, unnecessary elements remain on the arch blocks, such as transportation loops or stops for "dividers".
They are cut, and the cut points are cleaned.
A device for dismantling the avanbek.
Avanbek is an auxiliary guiding structure in the form of a cantilever, attached to the front of the sliding superstructure during the construction of the bridge.
Three geodetic GPS receivers were used for precise positioning of the half-vaults of the arch during sliding.
Two at the ends of the first blocks, and one in the middle on the bridge itself.
The thrusting of the arch lasted 129 days.
Rainy night before the final stage.
It remains to go 1 meter 10 cm!
The fitter carries out visual control of the joining accuracy.
Device for coarse positioning of half-arches of the arch according to the "Dad-Mum" type
The vault blocks are mounted on high-strength bolts with a diameter of 22mm and lengths from 65mm to 120mm.
The joint of two blocks requires 563 bolts.
The historical moment is the completion of the docking of the arch.
The photo clearly shows the oval holes into which the cables will be inserted.
Inside the arch blocks there is a passage for operational control of the tension of the cables and bolts.
Shrouds supporting temporary supports.
In May, the builders will start installing the cable-stayed system. A total of 156 cables will be installed (the largest of the cables is 109 meters long).
All installers and welders working on the bridge are authorized to work at height.
The usual schedule for local workers is 2 shifts per day + 2 shifts per night, followed by 4 days off. The shift lasts from 8:00 to 20:00 and vice versa). There is another option - a shift of 15 shifts in the daytime, then 15 days of rest
Installers calibrate the friction joint.
Each bolt must be tightened to a certain force (calibration), for this they are tightened with a torque wrench.
After tightening, the customer's representative accepts the bolts.
Crawler crane XCMG QUY150 (China) with a lifting capacity of 150 tons for the installation of arch blocks.
"Crossings" - their task is to give the arch rigidity.
In total, specialists from Mostootryad No. 38 of the Novosibirsk branch of Sibmost OJSC installed 88 blocks of the arch with a total weight of 3607 tons.
Against the background of the Communal Bridge
The total cost of the bridge is estimated at 14.8 billion rubles.
The construction of the bridge began in 2010.
It is assumed that the bridge will be commissioned in late September-early October 2014.
Obviously, the Bugrinsky bridge will become a new symbol of the capital of Siberia.
Thanks to Sibmost OJSC for organizing the photography, as well as a special thanks to Artem Kiryanov for his help in collecting information!

In Novosibirsk, the construction of the third road bridge across the Ob, named Bugrinsky. On Wednesday, October 8, 2014, the grand opening of this large-scale engineering structure will take place. On the one hand, I feel a slight feeling of regret, because in the almost five years that have passed since the drilling of the hole for the first support, I have become accustomed to following the construction site, rejoicing at every successfully completed stage and periodically photographing some moments of construction. On the other hand, I am glad that the city will finally receive such a long-awaited bridge with the largest arched span in Russia and the CIS countries. I propose to briefly recall how the red arch rose over the Ob before our eyes.
In this review I will not describe in detail how the pre-design and design work was carried out, how funding was sought, how the authorities of Novosibirsk and the builders of Sibmost solved the emerging problems. For those who want to live it again, I suggest to get acquainted on the Skyscrapercity.com forum with the topic dedicated to the Bugrinsky bridge and has over 260 pages. There are disputes, opinions, experiences and many photos of the construction, taken by the forum participants. I will try to present the history of the creation of the bridge rather briefly - in the form of photographs and small explanations to them.
Initially, three options for the solution of the superstructure above the axis of the fairway were considered - post-beam, ...

During the design, some details of the arch were clarified, although the overall dimensions remained the same. A short video was made, in which a model of the bridge was already presented, as close as possible to the object that was actually erected in Novosibirsk. The same video explains the features of the selected structural system - a mesh arch.

On October 8, 2014, traffic on the Bugrinsky bridge was opened by the President of the Russian Federation Vladimir Vladimirovich Putin. Novosibirsk people have been waiting for this moment for four and a half years. Construction of the bridge began in February 2010 and ended in September 2014. During this time, Sibmost OJSC has created a unique architectural object.
The uniqueness of the bridge consists in a record large arch span - 380 meters. It is the largest arch span in Russia and the largest mesh arch in the world. To transfer the load to the arch vault, a cable-stayed system consisting of 156 cables is made. The way of building the bridge is also unique. More than one bridge in the world has not been built by the method of vertical radial sliding of the arch.
The name of the Bugrinsky bridge was determined by a vote in December 2013. Five names of the bridge “Nikolsky”, “Solnechny”, “Raduzhny”, “Krivoshchekovsky” and “Bugrinsky” reached the final. The Bugrinsky Most stepped forward with a small margin.
For the construction of the bridge, 320 private houses were demolished (280 on the right bank and 40 on the left). The total cost of construction, including the cost of resettlement of people, amounted to 17.1 billion rubles.

Development plans
The Bugrinsky Bridge and the highway from Bolshevistskaya Street to Vatutin Street are only the first stage of construction, 5.5 km long. The second stage of construction should provide access to the intersection of Vybornaya and Kirov streets.
In the future, the section of the road with the Bugrinsky bridge will be included in the large-scale project of the South-West transit of Novosibirsk. This will allow to connect it with the already under construction Eastern bypass of Novosibirsk and get access to the federal highway M-52 and Gusinobrodsky tract, and, on the other hand, to get to the federal highway M-51 (Omsk tract) and, accordingly, get access to Tolmachevo airport.
The communal bridge was opened on October 20, 1955. It became the first automobile-tram-pedestrian bridge across the Ob in Novosibirsk. Despite the savings during construction, the bridge has very organically blended into the style of the city and has become one of its symbols.
On June 3, 1965, the bridge became famous all over the world thanks to one occasion. Valentin Privalov, a military ace pilot, flew under one of the spans of this bridge a meter from the water. This event had a wide resonance even abroad. They wanted to put the pilot on trial for hooliganism, but by order of the Minister of Defense of the USSR he was again allowed to fly.
The Novosibirsk metro bridge was built in close proximity to the Communal Bridge. Initially, it was even planned to use its supports for construction. Its length is 2145 meters, making it the longest covered metro bridge in the world. Its construction was attended not only by workers, but also by the townspeople who went out to the subbotniks.
Interestingly, the length of the bridge is not the same in winter and summer. In winter, it shrinks, and in summer, on the contrary, it stretches by 50 cm, so rollers are installed on the supports. The reason for this is large temperature differences.
Dimitrovsky bridge
Dimitrovsky Bridge is a bridge across the Ob River in Novosibirsk, connecting Dimitrov Avenue on the right bank. Construction of the second communal bridge began in 1971. Its constructive solution is unique: the bridge is all-welded, without bolts, in "northern design". Prior to that, similar bridges were built in Kiev and Moscow. This is the most complex structure that the Novosibirsk bridge builders had to deal with. Almost 25 km of welds were produced. The six-span bridge was opened to traffic on November 4, 1978.
Olovozavodsky bridge
The Olovozavodskiy (Bugri) nskiy bridge in Novosibirsk is the third bridge across the Ob, which will connect the Kirovskiy and Oktyabrskiy districts of Novosibirsk. In the future, the bridge will become an integral part of the promising continuous high-speed highway "South-West Bypass" of Novosibirsk, which will connect the federal highways "Baikal" and "Chuisky tract".
Site selection and feasibility studies were carried out by the Transmost design institute (Moscow) in 1992. Construction began in February 2010 and will be completed in September 2014
The first railway bridge
The most difficult task turned out to be the choice of the place where the Trans-Siberian Railway will pass through the Ob. Initially, the choice fell on Tomsk, but then the bridge would have to be built where the Ob spills every spring. The only narrow section was on the territory of present-day Novosibirsk, but then the highway will run south of the planned one.
Construction began. The bridge consists of nine spans, lying on stone supports made of local granite, laid on the granite bed of the river. It is interesting that the changes that N. A. Belelyubsky introduced during the construction process, which included the arrangement of a “free carriageway”, later became known in the world bridge construction as the “Russian system”.
Almost 100 years later, the USSR Ministry of Railways decided to build a new bridge with the subsequent dismantling of the span structure of the old one, which no longer met modern standards for the passage of heavy trains through it. After the completion of the construction of the new Komsomolsk railway bridge, which was inevitably inferior in aesthetic qualities to its predecessor, the "old" bridge was no longer needed. However, it continued to be used by passenger trains passing through the city center.
Currently, there is only one track for trains crossing the old bridge. But its supports and embankments on the banks have been preserved, which makes it possible to re-build additional spans. In the City Beginning Park, on the city embankment, one old span is even kept as an exhibit.
Attractions of Novosibirsk
The bridge for Novosibirsk is not just a river crossing. The city, spread out on two banks of the river, cannot be united without them, preserve the integrity acquired almost 125 years ago. "All about new buildings" studied the history of Novosibirsk bridges and the prospects for the construction of new ones.
The bridge, it would seem, is a completely utilitarian object. Its function is to connect the two banks of the river so that people and goods can move between them, but traditionally bridges are given a deeper meaning. Hence the Kisses Bridge in St. Petersburg, and the Bridge of Sighs in Venice, and the Suicide Bridge in San Francisco.
First bridge
After a long search, a place for the construction of the first railway bridge across the Ob was found near the village of Krivoshchekovo. The bridge was built according to the design of Professor Nikolai Belelyubsky, an outstanding civil engineer and scientist in the field of structural mechanics, and had nine spans, which lay on stone supports made of local granite, laid on the granite bed of the river.
Construction lasted four years and cost about 2 million rubles.
In 1896, a bridge was tested, along which four steam locomotives passed, and on March 31, 1897 it was opened to traffic. In the 1930s, after the completion of the construction of the Komsomolsk railway bridge and the creation of a cargo bypass for Novosibirsk, the old bridge lost its former significance and began to be used, as a rule, for passing passenger trains traveling through the city center. At present, the superstructures of the old bridge have been dismantled, and trains are again moving along the same track across the bridge. At the same time, the bridge supports and embankments on the banks are preserved, which allows, if necessary, to re-build the bridge to a double-track. One span structure on the city embankment in the City Beginning park has been preserved as a museum piece.
Komsomolsky bridge
To unload the main passage of the Trans-Siberian Railway with access to the mining enterprises of Kuzbass at the end of the 20s of the last century, it was decided to build the Ob-Inskaya branch with a 900 m long bridge crossing over the Ob River. m, and the floodplain part - an arcade of eight stone arches with spans of 19.5 m.
The construction of the supports began in December 1930. The construction of the pillars was completed in September 1931, and on January 7, 1932, temporary traffic opened on the bridge. The bridge was built in 1.5 years, the domestic bridge building did not know such a pace. Construction and reconstruction works in Siberia were carried out by the SIBSTROYPUT organization. The management of the construction of the bridge petitioned to assign the name of the Komsomol to the bridge. Since then, it has been called Komsomolsky.
New railway bridge
In April 1984, the installation of the second channel bridge spans - metal trusses - was completed on the supports of the first railway bridge across the Ob. The construction of the spans began in 1974. For this, foundations were dug for approaches to the bridge, where 78 thousand m 3 of soil was laid, and a road more than a kilometer long was built on them to the left-bank support of the bridge for the supply of metal, concrete and other materials. To check the reliability of the existing supports, Leningrad specialists drilled the bodies of the bridge supports and rock foundations on which the supports of the old bridge stood. It is concluded that it is possible to build a second superstructure of a railway bridge on the same bridge supports, the project of which was developed at the Moscow Institute of Giprotransput. The builders erected seven reinforced concrete pillars on the foundations of the bridge's former ice cutters, erected two shore piers. The installation of the span trusses between the supports of spans of 100 m was carried out by the method of hinged assembly, from support to support, using cranes passing along the top and inside the span of the trusses. An effective method of building a bridge without auxiliary scaffolding, floating means was applied for the first time in Novosibirsk.
Oktyabrsky (Communal) Bridge
On October 9, 1948, the Council of Ministers of the USSR adopted a resolution "On measures to help the city economy of the city of Novosibirsk", in which the Government allocated 30 million rubles. for the improvement of the city in 1949-1950. The project of the bridge and the entire complex of bridge crossing structures was carried out by the design engineer G.D. Popov and architect K.I. Yakovlev. The bridge consisted of two parts: the overpass of the right bank of four spans, two of which blocked the street. Bolshevik and river parts of the bridge of seven spans 120 m long each. Components of the bridge crossing: embankment-dam of the left bank, upstream and downstream stream-guiding dams on the left bank with a total length of over 500 m and a height of more than 5 m, an overpass across the railway tracks on the right. The bridge had two tram lines, two double-lane traffic lanes and two pedestrian walkways. The total width is 24 m. Structurally, it met the latest technological advances and was combined. The metal superstructure in the above-water part, 800 m long, with the above-ground part of 1,100 m, consisted of rigid I-beams. In total, there are eight beams across the width of the bridge, supported by flexible riveted arches. The consoles of the pedestrian part of the bridge were made of reinforced concrete, and the upper part of the superstructure was also made of it - slabs 15 cm thick, each weighing three tons, monolithic between themselves at the joints with concrete. Asphalt was laid on top of the waterproofing. The superstructure rested on reinforced concrete supports and rose 30 m above the water level. The bridge was fenced with cast iron railings, the bank abutments were faced with gray Siberian granite from the Gusinobrodsky quarry.
Oktyabrsky, or Kommunalny Bridge, whose construction was estimated at 128 million rubles, was opened in November 1955.
Its appearance gave a great urban planning effect, creating a new situation in the city's road transport network. New highways appeared, such as, for example, K. Marks Avenue, which became the main street on the left bank of Novosibirsk. The existing streets - Bolshevistskaya, Suzunskaya (Voskhod) - were also transformed, they became the main thoroughfares in the Oktyabrsky district. The cleared Ob embankment was transformed into a coastal park, which is so necessary for the city and gives a significant aesthetic effect in its panoramas. The bridge areas of the river banks are being intensively built up, the orientation of the building has changed: it began to grow to the south, southeast. From now on, the city-wide center of Novosibirsk is developing towards the bridge and along both banks of the city, and on the right bank it moves to the Oktyabrsky District. A number of streets, for example, Nizhegorodskaya, Sacco and Vanzetti, Kirov, which previously seemed to be the “distant outskirts of the city”, found themselves within the future boundaries of the center's core, and the bridge itself became one of its compositional urban planning axes. Kommunalny bridge, which is a historical monument and is depicted on the coat of arms of Novosibirsk.
The construction of the pillars of the communal bridge began in December 1930, and on January 7, 1932, temporary traffic opened on the bridge. The bridge was built in 1.5 years, the domestic bridge building did not know such a pace.
Dimitrovsky bridge
During the 70s, the planning structure of the city underwent a number of transformations, which was primarily associated with the second communal bridge across the Ob. Its construction began in 1971. The bridge is a complex complex of structures, consisting of the bridge itself (cost - about 20 million rubles) with a carriageway length of 701 m, a width of 30 m, with a six-lane movement along it. The bridge set also includes approaches, entrances, transport interchanges, which together with the bridge make up the length of the entire crossing of 5 km. Its total cost is 53 million rubles.
The bridge is unique in terms of its design: its elements did not have bolted connections, it was all-welded. Almost 25 km of welds were applied by the builders to the steel structures of the bridge. The first seam was welded on December 25, 1975. At all stages of the construction of the bridge, scientists from NIIZhT also worked, studying the distribution of stresses in the structures, comparing them with the calculated and theoretical ones. The steel elements of the bridge are made of low-alloy chromium-nickel steel, which has almost halved their weight. The structure of the bridge consisted of two coastal parts and a surface span covered by main steel beams 631 m long, interconnected with reinforced concrete slabs. Their top served as a carriageway. At the joints of the parts there are expansion joints, which, under the influence of temperature changes, dampen the movement of the bridge (by more than 20 cm).
The entire superstructure is installed on seven supports: five intermediate and two onshore, together forming six spans, two of which are navigable. The bridge and the entire complex of structures were opened to traffic only on November 4, 1978.
Metro bridge
The technical design of the metro bridge was developed by the Lengiprotransmost Institute and in 1978 approved by the USSR State Construction Committee. The bridge is a box-shaped metal gallery girder about a kilometer long with two-way high-speed metro trains. The gallery-beam is supported by concrete channel V-shaped supports, river "bulls". Chief engineer of the bridge project - S.V. Tsygankov, engineer - K.P. Vinogradov.
The total weight of the bridge superstructure was 6.2 thousand tons, which is almost equal to the weight of the famous 300-meter Eiffel Tower in Paris. The installation of the metro bridge was completed in February 1985. The Novosibirsk metro bridge is the longest of such bridges in the world.
Bridge over the hydropower plant gateway
In 2007, in Novosibirsk, in a solemn atmosphere, traffic was opened on a new bridge across the HPP sluice, which is one of the four main objects included in the federal target program “Construction and modernization of public highways”, the construction of which was completed in 2007. This program is being successfully completed in Novosibirsk by putting the bridge into operation. The construction cost amounted to 280 million rubles.
The total weight of the bridge superstructure was 6.2 thousand tons, which is almost equal to the weight of the famous 300-meter Eiffel Tower in Paris. The installation of the metro bridge was completed in February 1985. Novosibirsk metro bridge -
the longest of its kind in the world.
The length of the bridge crossing is 270 m, the width of the roadway is 10 m. During the construction of the bridge, the builders had to face a number of difficulties. For the first time, for example, asphalt was laid in winter conditions, and the top, finishing layer was laid in spring. During the construction of the bridge, the technology of lower layers of asphalt concrete in winter conditions was applied for the first time. Another novelty is a special fence that will prevent foreign objects from entering the lock structures.
Bugrinsky (Olovozavodsky) bridge
Among the unusual modern bridges, during the construction of which unique technologies were used, experts also name the Bugrinsky Bridge in Novosibirsk. The structure with the largest arched span in Russia opened in the fall of 2014. Bugrinsky Bridge is an example of the fact that modern bridge structures solve not only transport problems, but also become local attractions. So, the main source of architectural expressiveness in bridge construction is the load-bearing structural elements, and not the decorative treatment of their individual parts. The Bugrinsky Bridge is a unique object in terms of its technical and architectural characteristics. For the first time in world practice, the arch span of the bridge 380 m long and 72 m high was erected by the method of vertical radial sliding.
The Bugrinsky Bridge is one of the elements of the continuous traffic highway provided for in the general plan of the city, connecting federal highways M-51 Novosibirsk - Omsk and M-52 Novosibirsk - Biysk - Tashanta and the road Novosibirsk - Leninsk-Kuznetsky. The bridge crossing is only the first stage of the highway, the total length of which is 22 km. The length of the bridge crossing is 7.4 km, including the bridge - 2.225 km (the channel part - 1,664 m, the floodplain part - 561.2 m), the width of the bridge - 33.5 m. The complex includes junctions at different levels at the intersection with Vatutin, Bolshevistskaya and Vybornaya streets, an overpass at the intersection with the Altai railway, as well as pedestrian crossings.
A feature of the Bugrinsky bridge is its complex geology: the bridge section crosses a fault, therefore, a reliable foundation for the supports of an ordinary girder bridge in the central part of the channel could not be found even at a depth of 90 m. The authors of the project - specialists of ZAO Stroyproekt Institute from St. Petersburg - proposed an arch bridge option.
Construction of the bridge began in 2009 and the grand opening took place on October 8, 2014.
Central bridge
For the first time, the project of the fourth, Central Bridge, which received a working name for its location, was considered in 2012 at a meeting of the Architectural Urban Planning Council of Novosibirsk. The prospective Central Bridge will connect the eponymous district on the right bank of the city and Leninsky, located on the left bank. In accordance with the general plan of the city, the bridge will pass in the alignment of the Ippodromskaya and Kamenskaya highways on the right bank and reach the left bank in the area of \u200b\u200bul. Station. The length of the bridge from the junction on Yuzhnaya Square to the junction of Truda Square will be 5.1 km, of which the length of the above-water part is 850 m. According to the project, the bridge will fit into the existing road network of the city with the help of multi-level junctions, as well as an overpass at the intersection with the railway in the area of \u200b\u200blakes on Gorskaya. The interchange on Yuzhnaya Square will be three-level: Red Avenue will turn into ul. Bolshevik on the overpass, the Kamenskaya highway will reach the bridge under it, and st. The Factory Room will become 2.5 m lower and create a third level. In the right bank, as conceived by the authors of the project, the main pedestrian crossing will be underground, and the crossings from Megas and the bus station to the Gorodskoe Nachalo park will be above ground.
On the left bank in the floodplain - from the Ob to st. Starting - the bridge will pass at a height of 10 m. At the intersection with st. The starting bridge will connect with st. Podgornaya, because create a connection with st. Gorskoy is extremely difficult, since the relief difference here is 14 m. There are two traffic lights at the intersection on Truda Square: at the intersection with ul. Planning and on the ring to pass the main traffic from the street. Stanislavsky. As a result, roundabouts and traffic lights in this area will completely disappear, traffic from all adjacent streets will be connected continuously through interchanges. Public transport with trams in this place will be brought to the "second floor", a whole complex of pedestrian crossings has been thought out. At the same time, on the right bank, a convenient exit is thought out only from the Hippodrome highway. The bridge is supposed to have six lanes - three lanes in each direction, and one of them is only for public transport.
81 residential buildings will be demolished for the construction of the bridge: two-story buildings and a private sector. This is 4 times less than the preparations for the construction of the Bugrinsky Bridge, where 360 \u200b\u200bhouses were demolished.
But the main innovation of the bridge is that it will be paid, since it is being built partly at the expense of the concessionaire. The company that will become the investor of the bridge was outstripped in August - this is LLC Siberian Concession Company. Work on the site is scheduled to begin in 2018.
Zaeltsovsky bridge
The master plan for the development of Novosibirsk envisages, in addition to the two existing ones - Oktyabrsky and Dimitrovsky - the emergence of five new bridges across the Ob, i.e. three more, except for Bugrinsky and Central. One of them - in the Zaeltsovskiy district - will be built downstream of the Ob, where the promising Yeltsovskaya main line should go to the promising fifth bridge across the Ob. On the left bank, the bridge should come out in the Zaton area.
In particular, the bridge is mentioned in the Pribrezhny district planning project. According to the project of LLC "Personal creative workshop of architect Deev NN", which was based on the general plan, Zaeltsovsky bridge is located just north of the 2nd Yeltsovka river in the area of \u200b\u200bSaranok island.
The designers proposed to climb the Zayeltsovsky Bridge along Sukharnaya and Stasova streets. It was supposed to build a dual-purpose bridge: for cars and for the metro of the Dzerzhinskaya (green) line of the Novosibirsk subway, which after pl. Garina-Mikhailovsky will have to make two more stops along Vladimirovskaya and then spread to the left bank.
The need to build the Zaeltsovsky Bridge is dictated by the development of Rodnikov, Snegirey, the territory of the Novosibirsk-Severny airport, as well as the Strizhi microdistrict.
The bridge played a key role in the life of Novosibirsk, turning the village of Krivoshchekovo, lost in the vastness of Siberia, into the largest transport and logistics hub in Russia. And judging by how many disputes, discussions, emotions the construction of each new bridge evokes in us, for us this is not just another crossing over the river, but the most important, one might even say, a sacred object.
