Bridge Department

In the 1980s, Lengiprotrans engineers worked on a project to reconstruct a road bridge across the supply canal on the road to the Estonian State District Power Plant. This project was carried out by order of the administration of the city of Narva. Its implementation made it possible to solve transport problems associated with heavy traffic on the city highways of the Narva - Estonian TPP section. 

In the 1970s, Lengiprotrans engineers were designing an overpass at the intersection of Leninsky Prospekt and Narodniy Opolcheniya Avenue on the Predportovaya-Narvskaya stretch. This interchange made it possible to solve the transport problems of the Kirovsky and Moskovsky districts of Leningrad (St. Petersburg). In addition, level crossings where the motorway intersected with the railroad tracks were eliminated. 

In the 1980s Lengiprotrans was involved in solving transport problems in the Komi Republic. Design of a road bridge under the direction of A.P. Petrova contributed to the solution of transport problems in Ukhta. Thanks to the rational organization of road traffic junction, a large overrun of urban transport was eliminated. 

In the 2000s, Lengiprotrans developed a project for the reconstruction of a city-wide highway of continuous traffic on the section from the intersection of Krasniy Znameni Avenue and Nekrasovskaya Street to the Stroitel stadium in the city of Vladivostok.

The reconstruction was required to increase the capacity of the highway section, eliminate the oversized existing structures and improve the environmental situation in the adjacent residential area.

In 1950-1960s Lengiprotrans developed a project for an overpass with Endla Street in Tallinn. The work was carried out as part of the reconstruction of the Tallinn railway junction.

In the post-war years, Lentransproekt's Bridges Department (since 1951 - Lengiprotrans) was engaged not only in the restoration of destroyed objects in the Baltic republics, but also in the design of new artificial structures in connection with the needs of the developing transport system.

In the period 1945–1952, the institute prepared a project for a new capital bridge across the Jura River in Lithuania.

In the post-war years, Lentransproekt's Bridges Department (since 1951 - Lengiprotrans) was engaged not only in the restoration of destroyed objects in the Baltic republics, but also in the design of new artificial structures in connection with the needs of the developing transport system.

In the period 1945-1952, the institute prepared a project for a new capital bridge across the Auxinen (now Golubaya) river in the Kaliningrad region. It is a left bank tributary of the Pregolya River.

In the post-war years, the Department of Bridges of "Lentransproekt" (since 1951 - "Lengiprotrans") was engaged not only in the restoration of destroyed objects, but also in the design of new artificial structures in connection with the needs of the developing transport system.

In the period 1945-1952, the Institute prepared a project for a new capital bridge over the Virvipu River in the Baltic States.

In the 1980s, Lengiprotrans developed a project for the construction of a pedestrian bridge at the intersection of Mäekalda Street with Oktyabrsky Avenue in Tallinn. Power supply was also designed at the facility.

In the 1980s, Lengiprotrans developed a project for an overpass at the intersection of Krengolm Avenue with the railways of the Ministry of Railways in Narva.

At the facility, the following were designed: longitudinal profile, spans, auxiliary structures, power supply.
