In the approved project, the placement of all mechanisms and lifting equipment, additional designs of the lifting building, directing lifting routes and others were carried out inside the bridge support without the device of external lifting towers. In this case, the very bridge support acts the role of the tower. This decision composedly connected in a single complex all the structures adjacent to the shipping unit, as well as the designed bridge transition. The lifting building in the pointed position is based on its own supporting parts installed on the supports. The total moving mass when lifting 9 m is 5400 tons, including 2700 tons of a span. In terms of its technical characteristics – the magnitude of the span and the moving mass – the new spreading of a reckless type surpasses all previously existing divorce spans of a similar structure. Currently, the construction of a bridge with a similar divorce span has been completed. Over the past 80 years, in the line of St. Petersburg, a new railway bridge crossing the Neva River under the 2nd railway road Glukhoozerskaya-Dolgorukov’s October Railway (Finland bridge) has appeared for the first time. The need to build this bridge has risen for a long time in connection with a decrease in the bandwidth of the existing building of the building of 1911. In addition to this urgent replacement, its divorce and overpass due to the emergency state required. Given that the second path route takes place in the immediate vicinity of the first path, the engineers and architects of the institute had to pay much attention to the solution of the issues of their mutual connection: this concerned primarily the silhouette of the bridge and the design of the divorce span. The Finnish railway bridge, built at the beginning of the century, is still deservedly considered an outstanding transport structure. The perfection of the engineering solution of span buildings developed by talented Russian engineers made it possible to create a design (a lattice arch with high puff), superior in terms of rationality of the use of material, lightness and grace of forms, all well -known railway flights. Therefore, the desire of the institute’s specialists, supported by the main architectural department of the city, to preserve the silhouette of this bridge was quite logical.
