Construction of a new fourth bridge over the Yenisei in Krasnoyarsk

Krasnoyarsk is one of the most avtomobilizirovannyh cities of Russia. The city registered almost 320,000 cars. In addition, during peak hours in urban traffic flows into the transport stream from the Krasnoyarsk agglomeration. Street network can not cope with the load. On the main directions of the system formed by many kilometers of traffic jams.

Construction of a new fourth bridge over the Yenisei in Krasnoyarsk was achieved by the sliding spans using hydraulic equipment of "Ehnerprom"

The scientific basis for the development of infrastructure congested street network is Computer Modeling, Based on the proven hypothesis that the traffic flow on the highways of the dependencies described in classical hydrodynamics. Designed on the principles of fluid dynamics computer model of street-road complex in Krasnoyarsk has identified that the most sophisticated of its elements are the three existing city bridges, insufficient bandwidth which is the main cause of traffic jams. Strategic solution to the problem is to create a new transport artery — the fourth bridge over the Yenisei. The optimal location of the future bridge alignment is defined in the same hydrodynamic model.

Powerful shunt between transport systems north-west and south-west of the city allows you to distribute traffic movement from the central part of the new high-speed line.

This reduces the traffic in the center of Krasnoyarsk. Nearly a third of the average rate of increase of traffic flow. Unload existing bridges.

4th bridge over the Yenisei in the street will nachinaetsya Kopylova in its intersection with Volochaevskaya. Most of the approaches is arranged on the viaduct, which preserves the transport system of the first level. With the commissioning of the fourth bridge, street Dubrovinskaya become one of the city's main thoroughfares. In place of its contiguity to the bridge will be a three-level interchange. The bridge will have six lanes. Its length along with part of the overpass will be more than a mile.

Another two-level interchange will connect the target of the future bridge with the main line of the right bank of Krasnoyarsk — street Sverdlovsk.

Hydrodynamic model of the road network of the city of Krasnoyarsk can solve complex nodal transport problems at the micro level. Another sore point of the city — the roundabout at the intersection of 2nd Bryansk, Bryansk and Kalinin.

The model allowed to adequately assess the current status of the node and to offer a whole range of two-level decisions — the overpass on the street Bryansk on way out of town and on Kalinin Street overpass on the second Bryansk (combined version of the multi-level interchanges).

According to the simulation of a project interchange, construction of which will lead to a complete solution of the problem of Bryansk rings.

Established hydrodynamic model of the road network in Krasnoyarsk — it's not just a tool for making ongoing operational decisions, but also a window into the future of the city.


Stages of the construction of the fourth bridge in Krasnoyarsk

Run-section of the bridge

Construction of the fourth bridge over the Yenisei in Krasnoyarsk — a complex engineering task, which will be implemented over the next four years.

In 2012 began the construction of high-power fields pile of hundreds of bored piles.

They will be the foundation for the piers of the bridge, a device which will continue for the first three years of construction.

For year-round ice-free in the river will be used specially equipped fleet of river boats.

In 2013, on the piers will begin construction of the main span of the bridge.

Work on installation of bridge spans on the main pillars of the bridge and will run for two years from the second half of 2013 to mid-2015

Isolation on the street Dubrovinskogo

Along with the development of the main course of the channel will be built coastal road junctions. During the first phase of construction on the left bank of the Yenisei River Bridge will merge with the street Dubrovinskogo. Complex shape curved ramps that provide high-speed, comfortable and safe connection to the transport network in Krasnoyarsk left bank, will be launched in 2013. And their full completion to coincide with the commissioning of the bridge in 2015.

Isolation on the street Sverdlovsk

Construction dvuhurovnevnego abutting streets Sverdlovsk and Sayan on the right bank of the Yenisei River will be started in 2013. In 2015, the upshot will merge with the right bank caught the overpass bridge and its construction will be completed by the entire ensemble of the engineering of a new bridge.

In 2015, efforts will focus on the full rehabilitation of the bridge and it will be fully prepared to take the traffic load. The result of four years of work will be the six-lane structure, length of main course which will amount to almost 2 kilometers. A total length of road junctions exceed 5 kilometers.

Development of residential areas

Town Planning Code of Russian deservedly carries the fourth bridge over the Yenisei to the class of unique engineering structures. Of even greater importance under construction bridge crossing takes in the light of the role he is to play in the development of the urban environment. It is no exaggeration to become the main transport axis around which to develop rapidly new investment sites for housing in the most picturesque part of the urban landscape.

Among the new residential areas on the right bank districts Duck and reach the flank. The landscapes of the left bank of the Yenisei transform neighborhoods Combine and Nicholas. It was the fourth bridge crossing will ensure their transport accessibility, making living here quality, convenient, comfortable.

New transport schemes that will result from the entry into force of the bridge will allow for the development of not only the construction sites that are immediately adjacent to the axis of the building, but the new residential areas are attracted to set up transgorodskoy highway.

Total volume of housing construction will be more than 3 million square meters of housing. Improve the living conditions of about 100,000 people.

Construction of the bridge will not only fundamentally change the intracity transportation and environmental conditions, but also to provide the prerequisites for efficient formation of agglomerations of Krasnoyarsk, its satellite towns and surrounding areas.

Established alternative transport will increase will increase the efficiency of the road network in Krasnoyarsk with federal trunk roads.
