In the early 1980s, Lengiprotrans developed a project for a bridge over the Emajõgi River in the alignment of Komsomola Street in the city of Tartu, Estonian SSR.
In the early 1980s, Lengiprotrans developed a project for a road overpass between the III and IIIa microdistricts in the Lasnamäe residential area of Tallinn.
Strengthening of the line was due to the fact that it was an important link in the railway network of the USSR and connected the Tallinn industrial region and the seaport of Muuga with other republics.
The Irtyshskoe - Karasuk railway line is the eastern section of the Central Siberian Railway. It was built according to the Lengiprotrans project in the late 1950s.
At the same time, a railway bridge across the Irtysh River was designed on the line. The bridge is located on the navigable section of the river. The pillars of the structure were designed taking into account the device in the perspective of the bridge for the second track.
The department of bridges of Lentransproekt (since 1951 - Lengiprotrans) developed a project for the capital construction of a bridge over the Nura river on the Karaganda railway in 1946.
The Karaganda road connected the regions of central Kazakhstan with the railway network, provided access to rich natural resources: coal of the Karaganda basin, copper deposits of Kounrad, Dzhezkazgan and Boschekul. The development of the productive forces that followed the construction of the highway turned the region into the largest industrial base of the USSR.
The Esil - Arkalyk railway line was designed and built in the 1950s. The line carries out freight transportation of bauxite ore from Arkalyk.
The bridges department of Lengiprotrans on the line designed a new railway bridge across the Ishim River.
In the early 1980s, Lengiprotrans developed a project for a bridge over the Kura River on the Osmaly-Ali-Bayramli (now Shirvan) section of the Azerbaijan Railway.
The Kura is the largest river in Transcaucasia, originating in the Armenian Highlands and flowing into the Caspian Sea. It flows through the territory of three countries: Turkey, Georgia, Azerbaijan.

Back in the pre-war period, Lentransproekt (since 1951 — Lengiprotrans) started design and survey work on the Kartaly — Akmolinsk (now Astana) — Pavlodar line, which became an important link in the South Siberian Railway. The line was supposed to contribute to the development of the industry of large coal deposits (Ekibastuz and Korzhenkul) and copper (Boschekul).
In the post-war years, the Institute also carried out major design work on the main railway, including the design of a large bridge across the Ishim River in Kazakhstan.
After the blockade of Leningrad was lifted, a group of specialists from Lentransproekt (since 1951 - Lengiprotrans) was engaged in designing the restoration of the destroyed transport infrastructure. 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 Luga River. The design and construction of these structures was carried out on a very tight schedule.
In 2000, Lengiprotrans took part in the design of the overpass between Dunaysky Prospekt and the railway tracks of the Vitebsk direction of the Oktyabrskaya Railway. The overpass connected the Frunzensky and Moskovsky districts of St. Petersburg.
The length of the structure is 807 m, including the overpass - 572 m, retaining walls - 140 m.
