In the 1980s, Lengiprotrans developed a project for an overpass in Vilnius at the intersection of the Southern Bypass with an access railway.
In the 1940s – 1950s, Lengiprotrans designed a new capital bridge across the Vilia (also Neris) river at 31 km of the Vilnius-Turmantas railway section of the Lithuanian railway. Working drawings for construction were prepared.
In 1946, the Engineering Geology Department of Lentransproekt (since 1951 - Lengiprotrans) developed a project to strengthen the Kaunas slope on the Lithuanian Railway in order to ensure the stability of the roadbed.
In the 1980s, Lengiprotrans developed a project for the construction of an overpass in Vilnius at the intersection of the Southern Bypass with the Vilnius-Kirtimai railway line.
In the 1980s, Lengiprotrans prepared a design for a washing and steaming station for servicing the Mazeikiai oil refinery at the Bugeniai station of the Lithuanian railway.
At the facility, the following were designed: external power supply, low voltage and outdoor lighting networks, a transformer substation, vacuum collection equipment for collecting light oil products.
In the 1950s, Lengiprotrans carried out design and survey work to strengthen the sick embankment at 107 km of the Siauliai - Klaipeda line in the Lithuanian railway.
In the 1960s, Lengiprotrans developed a project for the development of the external railway transport of the Klaipeda oil depot in connection with its expansion.
At the site, the following were designed: signaling devices and a technical inspection point with a compressor station, a lubricant distribution pantry with heating networks.

In the 1960s, Lengiprotrans developed a project for the reconstruction of the railway station at Klaipeda station in Lithuania.

In the 1950s, Lengiprotrans drew up a project to replace mechanical interlocking with relay interlocking with route control of switches and signals at Siauliai station.
In 1965-1966, a complex project of the station was developed, including the track section, power supply, water supply.
In 1982, design and survey work was carried out to reconstruct the Siauliai station in connection with the construction in the city of an enterprise for the supply of petroleum products for the State Committee for Petroleum Products of the Lithuanian SSR.
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.
