Krasnoyarsk is a city with a unique geographical location, as it is located immediately on the border of Eastern and Western Siberia. But the city itself is considered East Siberian, although the Yenisei River divides it into two parts. It turns out that the right bank is Eastern Siberia, and the left is Western Siberia.
Characteristic and terrain features
Krasnoyarsk has always been considered the largest city in Siberia. Thanks to its industry, this city was able to conclude an agreement with China, in which the second side can introduce its products to Krasnoyarsk. Thanks to the new settlers, Krasnoyarsk residents were able to learn a lot.
The city covers an area of 354 square meters. km and is divided into 7 districts, and only three of them occupy the coastal part. “Why such a large area?”, You thought. But the answer is simple: the city is very scattered on the map, and the distance between the districts reaches 8 km, on which there are usually wastelands or industrial zones. But now construction companies are building up wastelands, trying to use the land as efficiently as possible. The right bank of the Yenisei is called five-story, tram, old Krasnoyarsk. Connects the entire right bank of the longest street in Russia called Krasrab. In itself, this avenue is very diverse. It takes its beginning in the Leninsky district, and ends in the Kirovsky district. The most expensive apartments on the right bank are located here, right there are the circus and the Tourist Hotel. And the view of the Yenisei coast itself is very beautiful.
Bridges of Krasnoyarsk
Naturally, several bridges pass through the Yenisei, which adorn and complement the ensemble of the city. Anyway, any bridge is an incredibly beautiful architectural work that sometimes serves for centuries. The first bridge, which began to operate on October 17, 1961, is called the Communal. Its length is 490 and 410 meters and is represented by two bridges. At that time, this bridge was considered the longest in Asia. The second bridge is called Oktyabrsky. Its construction is all-metal, its width is 50 meters and its length is more than 2500 m. The construction of the Oktyabrsky Bridge began in the 1970s. The third bridge, called 777 or "Three Sevens" is designed for rail and road traffic. The width of the road is 20 meters, and the length is almost 700 meters.
Expected Results
Construction will be carried out in two stages, and the result will be a new fourth bridge. Krasnoyarsk is looking forward to the end of construction. The first stage will include the connection between the two banks of the Yenisei. The second stage will include the interchange on the left bank, which will be connected to the flyover. The technical indicators of the first stage will include: lanes, of which there will be 6; two multi-level forks for transport; 4 bridge over the Yenisei will be approximately 1562 meters long.
Public transport
The construction of a bridge in Krasnoyarsk will reduce the overall transport load on existing bridge crossings, reduce the mileage of vehicles through the city center. This bridge will help redistribute the flow of cars and will make it possible to increase the speed of transport by 25%. This will help protect the city from traffic jams, traffic jams and other traffic collapses.
Since Krasnoyarsk residents know that they live in a city with a very unfavorable environment, which has suffered not only due to climate change, but also due to human intervention (mining of coal, ferrous metals, burial of nuclear waste), the 4th bridge across the Yenisei will provide an opportunity to improve ecology of the city. And today it is one of the urgent tasks. This is especially true of the city center of Krasnoyarsk. Bridge 4 will allow 4 districts of the city to improve its environmental situation due to the new bridge, since more than 500 thousand people will live next to it.
Social significance
The new bridge will provide a large number of personnel and material opportunities. For construction, metal structures, inert materials, high-quality cement, large work teams, good construction specialists, which Krasnoyarsk has, will be needed. The bridge across the Yenisei will require about 2,200 skilled workers and the same amount for the production of building materials. Completion of the entire project is planned in 4 years. The 4th bridge over the Yenisei as a project is a very complex engineering task, which will be carried out for several years.
At the beginning of 2012, drilling of pile fields began, subsequently they became the foundation for the support of the bridge. Since 2013, metal structures for spans have been installed. Materials are supplied to the facility from a local metalwork factory. In general, the length of one beam will be from 18 to 21 meters, and the width is about 2.34 meters, weight - 40 tons. The total amount of the entire span that will be used to build the bridge in Krasnoyarsk will be 1365 tons.
Construction Results
To date, about 475 tons of metal structures have already been installed, which is approximately 12 beams on temporary supports. This year, it is planned to mount and erect 365 tons of metal structures. The project involved about 50 pieces of equipment and 500 bridges of various construction branches. According to the project, the installation of spans should be completed this year.
After the liberation of sites along the banks of the Yenisei, the front of all work will expand and will be launched on the construction of interchanges for transport. In 2015, work will be done on the arrangement of the bridge, at the same time it will be able to withstand all traffic loads. The total contract value will be about 12 billion rubles.
This bridge can be safely attributed to the class of unique structures in Russia. Around the bridge, residential areas will actively develop. About 3 million square meters will be built. m. of housing, where almost 100,000 people can live.
At the same time, curved overpasses are being built, and the entire engineering ensemble will be completed in 2016.
Transport connection
Thus, today the new 4th bridge across the Yenisei in Krasnoyarsk is a necessary and important project for the transport life of the town.
According to the degree of motorization, Krasnoyarsk is considered the second in Russia, since today it is here that there are 355 cars per 1000 inhabitants. It is worth noting that from 1986 to 2010 the traffic flow on the main bridges across the Yenisei increased from 4.5 thousand to 14 thousand cars per hour. At the same time, the throughput of the system of huge city bridges has remained constant for 25 years.
The fourth motor bridge is a more important construction for the city. The new bridge will significantly reduce the transport load on existing bridge crossings in the city, as well as increase the average vehicle speed by more than 25%. This mainly concerns more busy central highways, where it is planned to increase the flow rate to 30-34 km / h.
The introduction of a new bridge will allow reassigning traffic flows, avoiding traffic congestion and preserving the unity and working capacity of the city’s transport system.
Ecology of the city
Also, thanks to the construction of the newest bridge across the Yenisei, the ecology of the city, especially its central part, will significantly improve. The main expected environmental effect of the construction of the newest bridge will be the return of the situation with harmful motor vehicle emissions in the central part of the city to the level of 2006. It was then that the last time was recorded the minimum indicator of harmful emissions, which is about 2 times lower than the current one. Improving the transport and natural situation will happen in 4 districts of the town and the nearest suburbs, with a total number of residents living in them more than 500 thousand people.
Conclusion
Thus, we examined all possible aspects with the help of which it is possible to diagnose in one way or another that today a rather large-scale and very necessary project for the construction of a bridge is being implemented in Krasnoyarsk.
This bridge can be safely attributed to the class of unique structures in Russia. And we more than examined in detail what its features are and what basic functions will be realized with the help of this bridge for the city of Krasnoyarsk. The 4 bridge over the Yenisei will be a very significant event for most of the surrounding regions, since transport links with them will become very convenient and economically viable. It remains only to wait for the completion of construction and draw final conclusions about how profitable this project has become for the city and its local residents.
