The Nagatinsky bridge is a huge and complex structure, for the construction of which the authors of the project were awarded the USSR State Prize, the engineer Aleksandra Borisovna Druganova and the architect Konstantin Nikolaevich Yakovlev. By the way, A. B. Druganova is the only woman who designed bridges with railways. Her biography lists an incredible number of projects. She built bridges and rebuilt them after the war. And the talented female engineer was awarded the UNESCO Gold Medal for the design of the Riga Bridge overpass.
general information
This is not a simple bridge, but a combined one. There pass roads and a subway line. The Nagatinsky bridge is also unique in that it was first built on land to unload the traffic intersection. And after its construction, a canal for the Moscow River was dug under a bridge.
The construction of the bridge in 1969 greatly simplified the connection between two large areas of the city - Kozhukhov and Nagatina. Previously, people traveled for more than an hour, circling around through another bridge - Danilovsky (now Avtozavodsky). Now this metro bridge connects the Zamoskvoretskaya metro line. It is located between the Kolomenskaya and Technopark stations. The Nagatinsky bridge is considered the leader among the remaining metro bridges in the capital.
Technical Details
The construction allows road transport to cross Andropov Avenue from one bank of the Moscow River to another. Its length is 233 meters. And over the river spans of the bridge stretched 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 the strips is 34.2 meters.
The Nagatinsky bridge was conceived by engineers as a span in which a continuous beam of reinforced concrete consists of individual blocks. With the help of epoxy glue all joints are made. The beginning and the final stages of the bridge are made in the form of reinforced concrete trestles, inside which garages are made.
Beginning of reconstruction
Half a century has passed since the construction of the Nagatinsky bridge in Moscow. This is a significant period for such an overpass with the active movement of both cars and subway trains. It is completely justified that the authorities thought about the overhaul of the structure.
After a thorough check, the following shortcomings were revealed:
- depressurization of seams of beams;
- bridge piers sagging from extreme load;
- sagging beams supporting the subway path;
- the asphalt pavement needed urgent repair.
Already in mid-July 2010 a final decision was made on the need for repairs. It was originally planned that the work would last no more than 20 months. They decided not to completely block the Nagatinsky bridge for reconstruction, but to partially do the work in strips. Nevertheless, this section of the capital has a busy transport interchange.
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 do repairs longer, but not to create congestion. But the reconstruction dragged on for a long seven years.
Many years of work were not carried out at all, only one sidewalk and part of the bridge were blocked.
Litigation
Before the overhaul of the Moscow River began overhaul, a tender was announced between construction companies wishing to participate in this project. Goldenberg LLC won in an open competition. For three years, the work was tightened and not completed to the end. For a long time there was a court hearing on this issue.
Finally, the decision was not made in favor of this company. The contract was terminated at the end of September 2014. Then, red tape continued for a long time with an appeal, which the court also did not satisfy.
Only in 2015, a new team from Pelisker LLC set to work, which, under an agreement, must complete the reconstruction within the prescribed 20-month period. This means that the opening of the Nagatinsky bridge will take place no later than the beginning of February 2017.
