The Chyornaya River Embankment
River Barrier: The Chernaya River
Overall length: 2,852.4 m
Opened in: 1967
Engineers: E.A. Boltunova
The Chyornaya (Black) River Embankment is located in Primorsky District of St. Petersburg. It is located on both banks of the Chyornaya River, on the left bank - from Ushakovskaya Embankment to Kolomyazhsky Prospect, on the right bank - from Academician Krylov Street to Academician Shimansky Street.
The embankment has an original design which was originally proposed by engineer E.A. Boltunova for Pesochnaya Embankment (during construction of Pesochnaya Embankment this decision was refused). The grillage structure consists of prefabricated elements, and the concreting with sheet piling is carried out in the windows and free length of reinforcing bars from piles.
At the end of 1960 in connection with the project of the Komendantsky airfield development, the decision was made about watering of the Chyornaya River with the Kamenka River waters (excluding spring and autumn flooding). For this purpose a cross flooding duct with locks of 5.9 km length from the Kamenka River up to the headwaters of the Chyornaya River. On the river itself at a length of 2.5 km from the railway bridge downstream, it was proposed to build a permanent embankment with a low banked wall and a green slope, as well as permanent bridges instead of wooden ones.
The decision began to be realized in 1967 with the construction of Lanskoy Bridge with adjacent embankments.
At that, the construction of permanent facilities was performed in the following order: the bridges with adjacent embankments were build first, and then an embankment wall was erected between them.
As a result, on two bridges - Kolomyazhsky and Stroganovsky - wall units of the embankment are a part of the bridge abutment; the bridge embankment wall under Lanskoy Bridge is completely independent, but the embankment grillage under Chernorechensky Bridge is fixed to the bridge abutments with anchors.
The last bridge built was Kolomyazhsky Bridge with the embankment sections (1986) and the end section of the embankment on the left bank of the Stroganovsky Bridge to Golovinsky Bridge at the confluence of the Chyornaya River into the Bolshaya Nevka River (1990). Here, along the embankment an underground sewage collector was mounted with mines and emergency discharges to the river. The right bank opposite to this site has no reinforcements (the territory of the North Plant).
The Chyornaya River is the right tributary of the Bolshaya Nevka River, it begins in Lakhtinskaya lowland near Dolgoye (Long) Lake and runs into the Bolshaya Nevka River almost opposite the source of the Malaya Nevka River. Many rivers of the Neva River Basin flowing out the swamps has dark, opaque water, and due to this they got their names.
Wooden bridges over the Chyornaya River appeared in the middle of the ХIХ century.
