Over the years of its operation JSC Lengiprotrans has created projects of transport infrastructure facilities in all federal districts of the Russian Federation and abroad (for more details see section International Projects ). Thus, the institute has acquired a unique experience in prospecting and designing in complex natural-climatic and engineering-geological conditions. Design objects were located both in hot and arid countries - in Syria, Libya and Turkey, and in the northern regions, in the permafrost zone. Projects of the Institute were designed for the construction of transport facilities in conditions of shortage of soil, the presence of creopeps, karst zones, which is associated with the geography of the regions.
