The Baikal-Amur Mainline (BAM) is the largest railway passing through the territory of Eastern Siberia and the Far East in the direction of Taishet — Sovetskaya Gavan.
The Institute took part in all stages of the BAM design, starting from the pre-war period. When the all-Union construction of the highway began in 1970-1980, Lengiprotrans was instructed to design the Chara — Tynda section. On this site, the institute has designed 798 artificial structures, including 25 large railway bridges and 1 overpass.

In 1967 Lengiprotrans was commissioned to design the BAM Chara — Tynda section of about 670 km. The route was laid in the region of the Olekma-Vitim mountainous country through rugged ridges dissected by river valleys. On the Chara — Tynda line, the institute has developed designs for 798 artificial structures, including 25 large railway bridges and 1 overpass.
The bridge across the Chumysh River is designed on the Meret — Srednesibirskaya railway line. The new route was supposed to remove from the Trans-Siberian Railway the transportation of coal from the Kuzbass and the Kansk-Achinsky deposit, as well as complete the formation of the Central Siberian railway.

In 1960–1970, Lengiprotrans developed a project for the BAM Chara — Tynda section with a length of about 670 km. The route was laid in the region of the Olekma-Vitim mountainous country through rugged ridges dissected by river valleys. On the Chara — Tynda line, the institute designed 798 artificial structures, including 25 large railway bridges and 1 flyover.
In 1960-1970s Lengiprotrans designed a road bridge across the Khani River as part of the construction of the Baikal-Amur Mainline (BAM). The structure is located at 447 km of the BAM. Along the Khani river valley, the BAM route leaves the Charskaya depression to the east to the Olekma river.
The viaduct across the Biryulya river is designed on the Meret - Srednesibirskaya railway line. The new route was supposed to remove from the Trans-Siberian Railway the transportation of coal from the Kuzbass and the Kansko-Achinsky deposit, as well as complete the formation of the Central Siberian railway.
The length of the bridge is 457 m, the height of the supports is more than 52 m.
The bridge over the Vym River was developed by the specialists of Lengiprotrans as part of the construction of the Chinyavoryk - Timan commercial railway. The line was intended to drive up to the Sredne-Timansky mine in order to transport bauxite to the plants in the Urals.
For many years Lengiprotrans has been developing the railway network in the Syrian Arab Republic. The main task was to connect the Mediterranean ports of Latakia and Tartus with the eastern regions of the country for the export of goods (oil, cotton, wheat). Before the start of these works, Syria had only one railway.
During the Soviet period, Lengiprotrans made a great contribution to the development of transport approaches to seaports in the Baltic States. In the 1970s, the institute designed a road overpass across the railway tracks along Dzintaru street in the Ventspils port area.
Port of Ventspils is the largest transit port on the Baltic Sea. It carries out industrial processing and transshipment of oil, liquid chemical products, coal, timber and other goods.
Since its inception, Lentransproekt (since 1951 — Lengiprotrans) has been involved in the transport development of the Kazakh SSR. In the 1950s, the Kostanay — Tobol — Dzhetygara railway line was designed. The road was supposed to ensure the transportation of iron ores from the recently discovered Sokolovo-Sarbaisky deposit to the Magnitogorsk Metallurgical Plant. When developing the line on the Kostanay — Tobol section, a railway bridge over the Ayat River in the Kostanay region of Kazakhstan was designed.
