In 1950-1960s Lengiprotrans designed a bridge over the Abakan River as part of the construction of the Kyzyl - Mazhalyk (Aktovrak) - Abaza highway. The construction of the route made it possible to reduce the distance between the Aktovrak asbestos plant and the western regions of Tuva by more than 400 km.
The bridge was built on the Aktovrak - Abaza section on the territory of the Tyva Republic. The length of the bridge is 245 m.
In 1950-1960s Lengiprotrans designed the Kyzyl - Mazhalyk (Aktovrak) - Abaza highway. The road has republican significance and passes through the territory of Khakassia and Tuva.
The construction of the route made it possible to reduce the distance between the Aktovrak asbestos plant and the western regions of Tuva by more than 400 km.
The highway bridge was designed and built in the 1960s and is located on the 1198 km of the Leningrad-Murmansk highway (the current name is R-21 "Kola").
In the early 1980s, Lengiprotrans developed a project for a railway bridge over the Volkhov River in the Volkhov District of the Leningrad Region. The structure was designed as part of the construction of the second tracks of the Volkhovstroy — Koshta line, which is part of the Petersburg — Vologda railway. The project was driven by the prospect of increasing freight traffic between St. Petersburg and the industrial regions of North-West Russia.
During the Soviet period Lengiprotrans was actively involved in the design of transport infrastructure in the Baltics. This was largely due to the development of approaches to ports in the Baltic Sea. In the capital of Lithuania - Vilnius, the Institute has designed the largest number of overpasses.
In the 1970s, Lengiprotrans engineers developed projects for two road overpasses on the Drujos highway, which is the southern bypass of the central part of Vilnius. The structures are located at the intersection with the Subačiaus and Povilo Višinskio streets.
During the Soviet period, Lengiprotrans took an active part in the transport development of railway approaches and stations at the seaports in the Baltic States. For the development of the Ventspils station, the institute has designed an overpass in the railway park located in the Ventspils port area.
Ventspils is an out-of-class railway station on the Ventspils - Tukums II line in the city of the same name in Latvia. It was opened in 1901 with the original name Vindava. The station carries out the transit of goods from the seaport to the railroad.
The highway bridge across the Golden Horn in Vladivostok is one of the largest cable-stayed bridges in the world and has a record length of the main span. A bridge crossing connected Cape Churkin with the city center, making it possible to get from one area to another by car in a few minutes.
The railway bridge across the Yuribey River is the longest bridge crossing beyond the Arctic Circle. The facility is located on the Obskaya — Bovanenkovo railway line, the project of which was developed by Lengiprotrans in the 1980s for the development of the Bovanenkovskoye and Kharasaveyskoye oil and gas fields. Due to the economic crisis of the late 1980s, the pace of construction slowed down significantly. In 2004, a decision was made to resume construction, within the framework of which a bridge was erected over the Yuribey River.
The railway bridge over the Usu River is one of the longest in the European North. In addition, at the time of project development, it was the longest bridge designed by Lengiprotrans.
The artificial structure is part of the Synya - Usinsk line, designed to connect the city of Usinsk, the center of oil and gas production, to the country's railway communication. The bridge was commissioned before the railway line, which is an exceptional case.
Obukhovo is a stopping point of the Oktyabrskaya railway, located within the boundaries of St. Petersburg. The bridge crossing connected the Frunzensky and Nevsky districts of the city and provided a safe passage over the railway tracks.
