Nagatinsky bridge is a huge and complex structure, for the construction of which the authors of the project, engineer - Alexandra Borisovna Druganova and architect - Konstantin Nikolayevich Yakovlev, were awarded the USSR State Prize. By the way, A. B. Druganova is the only woman who designed bridges with railways. Her biography includes an incredible variety of projects. She built bridges and rebuilt them after the war. And for the project of the overpass of the Riga Bridge, a talented woman engineer was awarded the UNESCO Gold Medal.
General data
This is not a simple bridge, but a combined one. There are motorways and a subway line. The uniqueness of the Nagatinskiy bridge lies in the fact that it was first built on land to unload the traffic interchange. And after its construction, a channel for the Moskva River was dug under the bridge.
The construction of the bridge in 1969 greatly simplified the connection between the two largedistricts of the city - Kozhukhov and Nagatin. Previously, people traveled for more than an hour, driving around through another bridge - Danilovsky (now Avtozavodsky). Now this metro bridge connects the Zamoskvoretskaya metro line. It is located on the gap between the Kolomenskaya and Technopark stations. In terms of length, the Nagatinsky Bridge is considered the leader among the other metro bridges in the capital.
Technical details
The facility allows motor transport to move along Andropov Avenue from one bank of the Moscow River to the other. Its length is 233 meters. And over the river spans of the bridge stretched for 114 meters.
Transport moves along a single-tier metro bridge at the same level - both the metro and cars. In total, six lanes were made for cars: three - in one direction, three - in the opposite direction. The width of all lanes is 34.2 meters.
Nagatinsky bridge was conceived by engineers as a superstructure in which a continuous beam of reinforced concrete consists of separate blocks. All connections are made with epoxy glue. The beginning and the final stages of the bridge are made in the form of reinforced concrete flyovers, inside of which garages are made.
Begin reconstruction
Half a century has passed since the construction of the Nagatinskiy bridge in Moscow. This is a significant period for such an overpass with active traffic of both cars and metro trains. It is quite justified that the authorities are thinking about a major overhaul of the structure.
After careful testing, deficiencies were identified:
- depressurizationbeam seams;
- bridge piers sagging from extreme load;
- beams supporting the subway track sagged;
- The asph alt pavement was in urgent need of repair.
Already in mid-July 2010, the final decision was made on the need for repair work. It was originally planned that the work would last no more than 20 months. For the reconstruction of the Nagatinsky bridge, it was decided not to completely block, but to perform the work partially - in stripes. Still, this section of the capital has a busy traffic intersection.
Complete closure of the bridge would lead to a collapse on the roads of the capital. We decided to avoid this, considering that it is better to make repairs longer, but not create congestion. But the reconstruction dragged on for a long seven years.
For many years no work was carried out at all, only one sidewalk and part of the bridge were closed.
Litigation
Before the overhaul of the overpass across the Moscow River, a tender competition was announced between construction organizations wishing to participate in this project. The company "Goldenberg" won in the open tender. For three years, the work was delayed and not completed. For a long time there was a court hearing on this issue.
Finally, the decision was not in favor of this company. The contract was terminated at the end of September 2014. Then the red tape with the filing of an appeal dragged on for a long time, which the court also did not satisfy.
Only in 2015A new team from LLC "Pelisker" took over the job, which, according to the contract, must complete the reconstruction within the prescribed 20-month period. This means that the opening of the Nagatinskiy Bridge will take place no later than the beginning of February 2017.
Completion of overhaul
Muscovites can breathe a sigh of relief. Reconstruction is fully completed. 805 meters of the bridge and flyovers look like new. The builders have replaced the entire coating, the adhesive joints are fully injected, the pedestrian steps on the stairs leading to the bridge have been replaced, all utility networks have been rebuilt, beams, spans, etc. have been reconstructed.
"Nagatinsky bridge is one of the most complex and busiest. It includes not only automobile, pedestrian traffic, but also metro traffic. Serious communications are also concentrated near the body of the bridge, such as heat supply, water supply, gas supply and so on. "After the repair, the bridge looks like new. Many structures have been replaced. And I hope that this transport facility will serve Muscovites for another fifty years without any major repairs," Sobyanin said.
Although the combined bridge was not completely blocked, everyone felt the inconvenience - both pedestrians and drivers of vehicles. For the next half century, you can forget about all the inconveniences. The bridge will serve for generations to come.
The article briefly describes the Nagatinsky bridge of the capital, what significance it has for many people, what it is famous for, how its reconstruction went. Moscow authorities promise to bring in the near futureorder the rest of the buildings of the capital, which are in a deplorable state. These are roads, bridges, and underground labyrinths of subway stations. Soon Moscow will please both Muscovites and guests with its updated look. She deserves it!
