The Mikun - Syktyvkar railway line is a dead-end branch of the Northern Railway. In the late 1950s, the USSR government decided to build it. The project of the line was developed by the specialists of Lengiprotrans.
A bridge crossing over the Vychegda river, combined for rail and road traffic, was designed on the highway.
In 1961, the entire Mikun - Syktyvkar line was put into operation.
The highway overpass is designed at the intersection of the Vyborg - Kamennogorsk railway line with the Komsomolskoye - Priozersk highway near the Vozrozhdenie station of the Leningrad Region. The construction replaced the closed crossing PK 229 + 44.20.
An overpass with approaches allowed unhindered passage through the railway tracks on two levels, as well as approaches to the villages of Glubokoe, Vozrozhdenie, a stopping point of the 21st kilometer.
The Nekrasovsky overpass is the main road artery of Vladivostok, which connects the center of the Primorsky Territory and the seaports of the region with the federal highway Vladivostok - Khabarovsk. It was built in 1963.
In the late 1990s, Lengiprotrans developed a project for the reconstruction of an overpass with an extension of a reinforced concrete overpass in order to widen the carriageway and improve the environmental situation in the adjacent residential area. The overpass passes through Gogol and Nekrasovskaya streets at the intersection with Red Banner Avenue.
In the late 1990s, Lengiprotrans developed a project for a two-level highway overpass at the intersection of Karl Marx and Leningradskaya Streets in Khabarovsk. This made it possible to relieve traffic jams in the city center, increase the throughput of a busy transport hub in the direction of the airport and improve the environmental situation in the adjacent residential area.
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 Gorelovsky overpass was built in 1949 across the Gatchina railway in the alignment of the Krasnoselsky highway (Gorelovo) and Lenin Avenue (the Skachki stopping point). The movement along it was organized in 2 lanes, there are also 2 narrow sidewalks on consoles. The length of the overpass is 76 m.
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 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.
Port of Klaipeda is the northernmost ice-free port on the Eastern coast of the Baltic Sea and was a major transport center of the Lithuanian SSR.
In the 1980s, Lengiprotrans designed the Urengoy - Nadym - Sovetsky highway. The road starts from the Urengoyskaya main compressor station (GCS) in the area of the city of Novy Urengoy and ends at the Komsomolskaya compressor station in the area of the Sovetsky village near the existing Ivdel - Ob'ye railway line of the Sverdlovsk railway. The motor road runs along the route of the Southern Corridor of the main gas pipelines and is intended for servicing compressor stations.
