From the moment of its foundation Lengiprotrans took an active part in the transport development of Kazakhstan. In the 1950s, large-scale development of virgin and fallow lands began in the Kazakh SSR and in a number of adjacent regions. On September 20, 1954, the Resolution of the Council of Ministers of the USSR No. 1985 "On the construction of narrow-gauge railway lines in the areas of virgin and fallow lands development" was adopted. The design of most of the facilities was entrusted to Lengiprotrans.
In the late 1980s, the introduction of high-speed traffic into the railway network began in Russia. The high-speed highway St. Petersburg - Moscow (VSM-1) became the top priority, the project of which was developed by Lengiprotrans already in 1989-1994.
The bridge crossing over the Varda River was developed as part of the design of the Karpogory-Vendinga railway line, which is part of the Belkomur meridional highway. The road should ensure the transportation of natural and mineral resources from the regions of the European North of the Russian Federation.
The length of the structure is 124 m.
The Ingol - Latvian railway line is a section of the Kemerovo railway (since 1997 it became part of the West Siberian railway).
The road solved the problem of connecting the Kansko-Achinsky and Kuznetsk coal basins (KATEK and Kuzbass) to the railway network, in particular, access to the Trans-Siberian and Central Siberian lines. During this period, the government of the USSR adopted Resolutions to increase coal production, but the existing railways from Siberia to the center of the country could not provide the required freight traffic.
The Karpogory - Vendinga railway line is a part of the Belkomur (White Sea - Komi - Ural) meridian highway in the direction of Arkhangelsk - Syktyvkar - Solikamsk.
The Karpogory - Vendinga section should connect two dead-end lines and turn the Mikun - Arkhangelsk direction into a transit highway. This will directly link the two resource-rich regions and shorten the train route from the Komi Republic to Arkhangelsk by almost 400 km.
The bridge crossing over the Vashka River was developed within the framework of the design of the Karpogory - Vendinga railway line, which is part of the Belkomur meridional highway. The road should ensure the transportation of natural and mineral resources from the regions of the European North of the Russian Federation.
The structure is projected on 412 km of the line, 3 km from the Vending station.
Bridge length - 270 m, layout - 3x88 m.
In the 1990s, the construction of the bridge supports began.
The Ilyinsk — Krasnogorsk — Uglegorsk railway line is a projected section on the territory of South Sakhalin and is part of the Far Eastern Railway (Far Eastern Railway) system. The route should solve the problem of coal transportation.
Back in 1937, the Tomari — Ilyinsk line was built, but World War II prevented its continuation north to Uglegorsk.
In the 1950s, Lengiprotrans conducted a major expedition to select the direction of the railway line in the Ob-Irtysh basin. The road was supposed to facilitate the development of forests in the North of Western Siberia.
To select the direction of the route, aerial photography at a scale of 1: 30,000 was widely used. On-site office photogrammetric processing of images, production of contact prints and reproductions was carried out. Topographic work on the binding of aerial photography was carried out by 4 survey parties.
In 2010 Lengiprotrans began developing a project for a new railway line Sirte - Benghazi in the Great Socialist People's Libyan Arab Jamahiriya. The highway runs along the Mediterranean coast.
The road was intended for the transportation of oil products and the creation of transport links between the two port cities. Prior to that, the country had a poorly developed railway connection.
All design work was done on site. The work was complicated by the presence of sand dunes.
As part of the creation of a new station complex with a passenger station in the 1950s, Lengiprotrans developed a project for the building of the Kirov Railway Administration in Petrozavodsk.
