Location : Kamennostrovsky Bridge
Saint Petersburg.
The Kamennoostrovsky bridge across Malaya Nevka connects the Aptekarsky and Kamenny Islands in the alignment of Kamennoostrovsky Avenue. In 1760, the first bridge bridge was erected on 11 ships, designed by architect A.F. Vista. In 1765, it was replaced with a new floating bridge at 10 pits, and then the floating bridge was connected to the coastal abutments pushed into the river on piles. The bridge in this form was repeatedly repaired in a tree.
In 1811-1813, according to the design of engineer A. A. Betancourt, the first seven-span wooden arch bridge on wooden supports and stone foundations was built on the site of the floating bridge. The construction was carried out under the guidance of engineers A. D. Gotman and S. O. Panteleev. The total length of the bridge was 150 meters. In this form, the bridge has been operated for twenty years. In 1833, under the guidance of engineer P.P. Bazen, the support of the bridge was repaired.
In 1859, according to the project of engineer A. Stuckenberg, a complete reconstruction of the bridge was carried out, in which the arched system was replaced by a complex strut system. In 1875, the bridge was overhauled to strengthen the bridge for laying horse-drawn railway tracks along the bridge. In 1899, during the next major overhaul, the bridge was completely rebuilt in a tree and turned into an 11-span beam-split system of four wooden frames with a manual drive. In 1906-1907, in connection with the transfer of city railways to electric traction, under the guidance of engineer V. R. Pau-Pomarnatsky, work was done to strengthen the bridge.
In 1938, the Kamennoostrovsky bridge was completely reconstructed. Wooden girders were replaced with metal I-beams, and the manual drive was electrified. The bridge was 152.5 meters long and 18 meters wide. The bridge repair work was led by engineer P.P. Stepnov.
In 1953-1954, due to the increased intensity of traffic and increased loads, and also taking into account the dilapidated state of the bridge, a new five-span metal bridge was constructed with a draw span in the middle, according to the project of the Lengiproinzhproject engineers V.V. Demchenko, B. B. Levin and architects P. A. Areshev and V. S. Vasilkovsky. For the first time on the bridge, reinforced concrete slabs with asphalt coating were used for the wings of a movable span instead of ordinary wooden decks. The bridge was constructed simultaneously with the Ushakovsky bridge according to one project, the motto of which was “The invisible adjustable span”. This constructive solution turned out to be so successful that it was used in the reconstruction of the Liberty Bridge over Bolshaya Nevka.
On October 17, 1954, the bridge was open to traffic. In 1999, the bridge was overhauled.
