Road construction in Siberia this year goes to a new level — tens of billions of rubles will be invested in the construction of facilities that meet modern requirements for security and bandwidth. Overview of key projects prepared correspondents "RG".
In Novosibirsk, the "Building of the Year" is the third bridge across the Ob. The project is estimated at 14.8 billion rubles and is strategically important to the metropolis — kilometers-long traffic jams on the approaches to the bridges during rush hours have become a familiar part of the urban landscape. The authorities have assured the public that the construction is on schedule.
— Our task — to introduce this facility in 2014. Of course, it will be a major impetus for the development of the city. The third bridge is needed by all. We have proved this federal government, and it was decided to separate the region this year, a special subsidy of $ 2.3 billion. In addition, we are working to incorporate this major infrastructure project in the federal funding program for 2013-2014, — the governor of the region Vasily Yurchenko.
The bridge total length of almost six kilometers of highway will be part of a continuous movement "South-West transit" linking federal highway use M-51 "Baikal" and M-52 "Chuiski." Recall that the decisive factor in the choice of the technical project has an estimated cost of construction. Despite the visual appeal of a suspension bridge (one of the best examples — a bridge in Los Angeles), the cost in the post-crisis period was too high — 26 percent more than the arch.
Structurally, the third bridge, the working title of which — Olovozavodskoy, beam structure will be installed on the thirty-reinforced concrete piers made on bored piles. The height of the arch will be seventy meters, the total weight of metal with arch viaduct — 27,000 tons.
— Of the thirty supports 28 ready — said the president of the general contractor Albert Cat. — Now supports bridge builders working on the N 6 and N 7. The fifth and sixth of support will be the most powerful, as will be the key to the arch span length of 380 meters.
And on the left and on the right bank of the Ob is building around the clock on it employs more than 1.2 thousand workers. By the end of May, of 25,000 tons of steel mounted 12.6 thousand, and the project spans the length of the bridge is more than two kilometers.
In this case, on the left bank of the large-scale construction is noticeable stronger, as this year is actively building a traffic interchange in the streets and the Congress Vatutin N 4 overpass across the street Bolshevik. According to the plan, in 2012, work will be done by 95 percent. As deputy mayor of Novosibirsk, head of the city Department of Transportation and road resurfacing complex Valery Zharkov, in developing the concept of the interchange selected the most economical and easy to move option. The main permanent structure will overpass width of 43 meters with a span length of 66 meters. Feature of an object that crosses the street overpass under construction Vatutin angle. In connection with this movement in the area from the street to the street Suburban World closed at night.
— Six bands have to ensure supply capacity up to 2030 — said Zharkov.
According to preliminary estimates, Olovozavodskomu bridge will be held not less than 35 percent of all traffic across the Ob, the dynamics of the passage of more than seven million vehicles per hour. Estimated traffic will reach 135,000 vehicles per day. Today, in general it is more than 180,000 vehicles a day — the level of loading of the two existing bridges on the limit.
Fast, but free
The largest infrastructure project implemented in the Kuzbass region — construction of the high-speed highway first category, "Kemerovo — Leninsk— Novokuznetsk."
Last fall, was commissioned 25-kilometer stretch of four-lane highway, which is all over will be equipped with intelligent motion control. In addition to electronic road signs and CCTV cameras, it includes automatic weather stations, electronic signs showing drivers time, air temperature and road surface, as well as speed, wind direction, air pressure and visibility.
Highway with a high-strength asphalt surface and permitted speed of 110 kilometers per hour, opening on the federal highway M-53, already allows transit traffic to reduce the travel time. Instead of forty minutes by road from the Sukhoi interchange to turn on the village Sammy now takes a maximum of fifteen. Because the path is no longer passes through the village of Birch, Smirnovka and farm "Coast". The latter, in turn, benefit in terms of environment and safety. After all, the track "Kemerovo — Novokuznetsk," and — especially in the area before the Leninist per day on average runs of more than twenty thousand vehicles — five times more than other roads area. No wonder this area has always beat records on the number of mentions in the traffic police accident reports.
The construction of 25-kilometer stretch of highway in the four years were spent 5.7 billion rubles. And second, a length of 19.5 kilometers, will require even more serious commitment — not less than 7.5 billion. The reason for increased cost of kilometers — is not only an increase in the price of materials and work, but also the complexity of the terrain.
— The road passes through the ponds, and therefore will have to build the dam, — said the head of the regional directorate of roads Oleg Shurigin. — We will build two overpasses, transport interchange and the bridge over the River North Unga, the shores of which will strengthen with modern technologies.
Today, according to the regional administration, the contractors are working ahead of schedule. Disbursed more than 600 million rubles (contract amount for 2012). At this rate of movement and timely financing in the second section can be opened in September 2013. A year later, road workers will take to the finish line.
— Many offer a new line to make toll, but we defended our position, and the road will be completely free — said the governor Aman Tuleyev.
Omsk region, in contrast to its neighbors, "mega-projects" this year has not. However, no work roadster will not remain just will focus on the construction and repair of rural roads.
In 2012, a program of modernization of the regional motorways will carry out the first time from the regional road fund, which formed last year. Total funding, including federal subsidies of 3.8 billion rubles (in 2011 there were about two billion).
The project of rehabilitation of the road network in the village started in the Irtysh region in the past year. It's not just about the highways leading to the district center, but also the arrangement of transport links with the villages with a population of at least 125 people.
The villagers were waiting for this for a long time. And no wonder, because if the Omsk region in the south of the rural road network is more or less developed, the situation is critical in the north.
— After the Rain local roads turn into soap — said, "RG" resident of Kirgap Tarski district Vladimir Petrov. — The machine is easy deploys a hundred and eighty degrees. Stick — a piece of cake. So when the rain comes, the locals try not to go anywhere.
Now the villagers have a chance to stay in touch with the outside world. Last year, the region has already paved the road to the five locations. And this year, forget about off-road residents of nine more villages.
— On average, the constru
ction of one kilometer of road cost of fifteen million
rubles, — says the head of the FCC reform and Roads of the Omsk Region Dmitry Khristolyubov. — Federal funding will be part of the ten million, you need to add the rest of the regional and local budgets. We were quite happy with these conditions. According to the plan, by 2015, the builders should pave the way to 120 locations.
It is clear that the budget is not elastic, and would like to make as much as possible. Therefore, it is important to solve the dilemma — that were inexpensive and technology, and the work is done efficiently. It turns out that this problem is solved. An example is the five-kilometer road paved "New — SOSNOVKA", built in the Azov district of Omsk on innovative methods.
— To reduce the cost of construction, we used the cold recycling technology — says the director of enterprise-contractor Jacob Wagner. — Instead of expensive rubble, which is absent in the region, was used in-situ soil, reinforced cement. Significantly reduce the thickness of the pavement has allowed the use of geosynthetic fabric. As materials for the coating layers applied to the device organomineral emulsified mixture based on bitumen.
Engineers claim that the laying of the roadway from the use of such mixtures require seventy percent less energy than using hot asphalt. A life — greater than a road constructed by conventional techniques.
Discount on technology
In Krasnoyarsk, last week held a competition for the construction of the first stage of the fourth road bridge. The winner was the Novosibirsk company, which offered to build a facility for the twelve billion (fifteen percent below the reserve price).
Under the project, the bridge a total length of 1,200 meters with six lanes of traffic and two two-level interchanges on the right and left banks of the Yenisei River (total length of five kilometers) to be built in forty months. He is believed to greatly relieve urban roads — existing crossing the Yenisei overloaded.
As the representative of the contractor Vasily Ilyin, reduce the price by more than two billion rubles have been achieved through the use of modern bridge construction technology.
— The use of new technologies will allow us to build fewer temporary technological support in the river and direct bridge spans at the same time on three or four points. In this way we can reduce the time and cost of construction — said Ilyin.
According to the Minister of Transport of the Krasnoyarsk Territory Sergey Eremin, the cost of construction of the first stage of the fourth bridge in Krasnoyarsk, the federal and regional budgets are divided in half. For example, in the project estimate includes the cost of the relocation from the area of the bridge of about 200 families.
— People receive monetary compensation or ready housing — to choose from — promised the minister. He added that in 2012, out of the regional budget allocated 23 million rubles for the design of the second stage of the bridge.
To go around
In the Altai Territory road builders have begun construction of bypass road Byisk. This is one of the largest of the transport network in the region, the cost of which is estimated at one billion rubles. The project is included in the federal targeted investment program in 2012 and its implementation is financed from the budget of the Russian Federation.
It should be noted that the area around Chu tract Byisk in the region have started to build in 1995. But just introduced the first place — ten kilometers of the road to the bridge over the river Biya, after which the project was shelved. And now, after seventeen years, the opportunity to complete unfinished.
— Riding around the city needs — emphasizes Byisk Mayor Nicholas Nonquit. — Today, all transit flows Chuiski go straight through the science city. The traffic intensity is high enough, the city just "choking" of traffic load. Bypass will endure beyond the federal highway Byisk and let the entire transit traffic to the detour. This is the "unload" Bijsk, improve the environment, which for the city, claiming the title of "tourist gate of the Altai" is important.
Road builders promise in 2013 to commission a second bypass line — part of the route length of 10.15 kilometers with a two-tier transport interchange and underpass lighting. It will be equipped with road weather station, cameras and sensors excluding traffic. When laying the roadway planning to use polymer modified asphalt, featuring high strength and crack resistance. According to experts, the coating of about twenty to thirty percent more durable than conventional asphalt and can be used for seven or eight years without major repairs.
