After the blockade of Leningrad was lifted, a group of specialists from Lentransproekt (since 1951 - Lengiprotrans) was engaged in the restoration of the destroyed transport infrastructure together with the troops. According to the projects of this group, military units carried out temporary restoration of bridges destroyed by German troops during the retreat. Among these structures was a large bridge over the Narva River. The design and construction of these structures was carried out on a very tight schedule.
In the 1980s, Lengiprotrans began developing a project for the Obskaya - Bovanenkovo line, the northernmost railway in the world. The road was intended for the development of the Bovanenkovskoye and Kharasaveyskoye gas fields on the Yamal Peninsula. With the onset of the economic crisis at the end of the 1980s, the pace of track-laying dropped significantly. In 2004, the Yamal Engineering Center was established to resume construction. In 2010, the Obskaya - Bovanenkovo railway was put into operation.

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 designed for the intersection of Subačiaus and Povilo Višinskio streets by the highway.
During the Soviet period Lengiprotrans took an active part in the development of transport infrastructure in the Baltic countries. A large number of artificial structures were reconstructed, in particular the overpass along Tunelio Street in Vilnius.

Kupchino is a station of the Moscow-Petrogradskaya line of the Petersburg metro. A pedestrian tunnel was designed in the area of the Lengiprotransom station.
The project provides for the extension of the northern pedestrian tunnel in the western direction under the reconstructed section of the avenue with the arrangement of additional exits from the tunnel on the western side of the avenue.
The tunnel is a prefabricated monolithic structure on a natural foundation.
The main characteristics of the object:
In the 2000s, Lengiprotrans developed a project for a transport interchange at the intersection of Rossiysky Prospekt with the existing main road on the Dacha Dolgorukova - Zanevsky Post section. The overpass became the final link in the formation of the Central Arc Highway connecting Primorskoye and Peterhofskoye highways bypassing the center of St. Petersburg.
Engineers of Lengiprotrans have extensive experience in the design of transport facilities in the Far North. In the second half of the 1990s, during the construction of a road, the Institute's employees developed a project for a road bridge across the Nadym River in order to cross a water barrier.
In the 1980s, Lengiprotrans developed a project for a pedestrian bridge at the Lazarevka station in the city of Vyborg. The object is located in the industrial zone of the city, in the area of the service station.
