The tunnel provides a link between Kanonersky island and Dvinskaya street on Gutuevsky island. == History == Before 1983 it was only possible to get on the island by ferry (it was the last ferry line of Saint Petersburg) or a private boat,〔 daily across the sea canаl which was a crossing for more than 2 million people.〔(【引用サイトリンク】 script-title=ru:Речные переправы :: Энциклопедия Санкт-Петербурга )〕 Constantly operating the crossing was also necessary for transportation of cargoes from Big port Saint Petersburg.〔 Because of that on the Sea channel movement of courts sea-gauge to and width to , bridge building was refused. The decision to build a tunnel was accepted. The project was prepared by Lengiprotrans,〔 and the building work carried out by Giprostroymost. Geodetic maintenance of the building is carried out by Petersburg State University of Means of Communication. The Tunnel was built using a method of buried sections: in the preliminary dug trench five identical sections were laid, each of which had a length of and weighed about . This method was applied for the first time in the Soviet Union . The length of the site dipping sections totalled . For the building of the sections on the bank of the sea canal, the original dock-sluice was constructed. After sluicing the created sections, with the end faces closed by metal partitions, they were counterbalanced by water and transported along the sea canal to the place of immersion. It fell onto tackles that were joined to an earlier established section, forming a uniform design. For the control of the immersion, divers worked underwater.〔 After packing of designs from them have pumped out water and have built underground tunnels and portals; the full length of a tunnel was .〔 The tunnel has two lanes (on one in each part) and a footpath. Along with cables for electrical supply and communication; water supply and central heating pipes connect Kanonersky Island with the city. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Kanonersky Tunnel」の詳細全文を読む スポンサード リンク
