In Moscow, after major repairs, the Bolshoi Kamenny Bridge was opened. Sergey Sobyanin wrote about this on his official page on the VKontakte social network.
In fact, the bridge was rebuilt again, while it was not completely closed and continued to perform its main function, said the Deputy Mayor of Moscow for housing and communal services and improvement Peter Biryukov… While one half of the bridge was closed for repairs, the other remained open for pedestrian traffic and public transport. During the work on the bridge, two lanes of traffic were kept in each direction.
Major repairs of the bridge have not been carried out since the moment of its construction, and during this time cracks appeared on its structures, the supports were dilapidated, expansion joints and granite cladding collapsed in some places. According to experts, some of the bridge elements were in a pre-emergency condition – with a service life of no more than two to three years. During the surveys, a decrease in the actual carrying capacity of the structure was recorded.
The project for the overhaul of the Bolshoy Kamenny Bridge was developed in 2019 by the decision of the Mayor of Moscow. Renovation work began in July 2020 and ended in August this year.
What became the Big Stone Bridge
During the work on the Bolshoy Kamenny Bridge, specialists restored the granite cladding and fences, put in order the concrete surfaces and metal structures, replaced the asphalt pavement and renewed the historical stained-glass windows.
The following works were carried out:
– repair of concrete surfaces of the bridge (33.8 thousand square meters);
– replacement of metal structures (total weight – 92 tons);
– painting of metal structures and concrete (72 thousand square meters);
– concreting of structures (7.3 thousand cubic meters);
– installation of a barrier fence made of granite blocks (960 running meters);
– dismantling and replacement of reinforced concrete structures of the bridge span, followed by the installation of asphalt concrete pavement and waterproofing of the roadway, approaches and sidewalks on an area of over 17.8 thousand square meters and the reconstruction of the heating network;
– reconstruction of outdoor lighting, architectural lighting and navigation signaling;
– reconstruction of storm sewers;
– reconstruction and restoration of granite cladding (6.5 thousand square meters), railings (1.74 thousand square meters), stained-glass windows (357 square meters) and external doorways (126 square meters).
Cultural heritage site with over 80 years of history
The Bolshoi Kamenny Bridge across the Moskva River was built in 1938 according to the project of architects V.A. Shchuko, V.G. Gelfreikh and M.A. Minkus (engineer – N.Ya. Kalmykov). He connected Serafimovich Street with Znamenka Street (then – Frunze Street), Volkhonka, Mokhovaya and Borovitskaya Square (then – Borovitsky Gate Square).
For more than 80 years of its history, the Bolshoi Kamenny Bridge has become an integral part of the architectural appearance of the city, in perfect harmony with the main dominant of the center – the Moscow Kremlin. The bridge offers excellent views of many sights of the capital – the Cathedral of Christ the Savior and the House on the Embankment. In 2007 it was recognized as a cultural heritage site.
At the same time, the Bolshoi Kamenny Bridge performs its main connecting function, providing traffic and pedestrian traffic from one bank of the Moskva River to the other.
The length of the bridge is 479.7 meters, the width of the bridge in the axes of the railing is 40.1 meters, including the roadway 33 meters and two sidewalks 3.55 meters each. The height above the level of the river reaches 11 meters.
After the completion of the overhaul of the main structural elements of the Bolshoy Kamenny Bridge and the opening of traffic according to a permanent scheme, by the end of this month, the finishing work of the under-stage spaces of the right and left banks, installation of engineering equipment and commissioning will be completed.
According to the calculations of specialists, the next major repair of the Bolshoy Kamenny Bridge will be required no earlier than 25 years later. The overall service life of the structure has increased by another 100 years.
Renovation of artificial road and transport structures of the city
The operating organization of the Bolshoi Kamenny Bridge is GBU “Gormost” – one of the largest specialized organizations in Russia for the operation of artificial structures. Gormost manages 2,183 urban objects, including 910 bridges, overpasses and flyovers (including elevated pedestrian crossings), 107 transport tunnels, 526 underground pedestrian crossings, 96 fountains, 108 embankments and several hundred other structures and engineering systems.
In 2011–2021, Gormost’s specialists overhauled over 380 objects, including 30 bridges, seven transport tunnels, 269 pedestrian crossings, four fountains and 17 embankments.
At the same time, during the reconstruction, all the elements that are subject to protection were completely restored at large bridge structures – objects of cultural and historical heritage. The work was and is being carried out year-round, the deputy mayor emphasized.
This year, the overhaul of the pedestrian tunnel under Begovaya Street and five bridge structures was completed: Bolshoy Kamenny Bridge, Tushinsky DK Bridge (across the Skhodnya River, Fabrichny Proezd), Skolkovo overpass (at the 53rd kilometer of the Moscow Ring Road), Kubinka – Bozhenko overpass ( part of the North-West Expressway – above the MCD-1 tracks), a pedestrian bridge at the 102nd kilometer of the Moscow Ring Road.
Currently, work is underway to overhaul 26 objects, including seven bridge structures: Stroginsky (across the Moskva River), Firsanovsky (across the Skhodnya River) and Andreevsky (across the Moskva River, connects Frunzenskaya and Pushkinskaya embankments) bridges, Bogdan Khmelnitsky Bridge (across Moscow – the river, connects the Berezhkovskaya and Rostovskaya embankments), the bridge over the Tsaritsyno dam (in the Tsaritsyno museum-reserve), as well as the Sevastopol (in the Yasenevo area) and Gorkovsky (at the 1st kilometer of the Moscow Ring Road) overpasses.
