Bridge Department

Design and survey work on the construction of the new railway bridge began immediately after the collapse of the span of the old structure on June 1, 2020, under the influence of the abundant flood waters of the Kola River.

The survey and design work was completed in a short time, which made it possible to restore communication between Murmansk and the center of the country in a record 105 days. On September 28, 2020, train traffic began on the new railway bridge.

In the 1980s, Lengiprotrans engineers designed various projects in the Baltics. Thus, by order of the Baltic Railway, Lengiprotrans has developed a project for a railway overpass in the town of Mazeikiai. Thanks to the implementation of this project, an important intercity highway with heavy traffic was developed and the safety of pedestrian traffic was ensured.

In the post-war years "Lentransproekt" (since 1951 - "Lengiprotrans") developed projects for the restoration of many transport facilities in the USSR. In 1946-1947, a project was prepared for an automobile bridge across the Alle River in the city of Pravdinsk, Kaliningrad Region. 

In the 1980s, Lengiprotrans engineers designed various projects in the Baltics. Thus, by order of the Baltic Railway, Lengiprotrans has developed a project for the reconstruction of a railway overpass in Vilnius. Thanks to the implementation of this project, an important intercity highway with heavy traffic was developed, and the safety of pedestrian traffic was also ensured. 

In the 1980s, Lengiprotrans engineers designed various objects in the Baltics. Thus, by order of the Baltic Railway, Lengiprotrans has developed a project for a railway overpass on the Vilnius — New Vilnia stretch. Thus, an important intercity highway with heavy traffic was developed. 

In the 1980s, Lengiprotrans engineers designed various objects in the Baltics. Thus, by order of the Baltic Railway, Lengiprotrans has developed a project for a railway overpass across the Leningrad — Tallinn highway at the intersection with the connecting railway lines of the Ülemiste — Maardu section. As a result, an important intercity highway with heavy traffic was developed. 

In the 1980s, Lengiprotrans engineers designed various projects in the Baltics. One of them was the overpass at the intersection of the road to the Pribaltiyskaya GRES with the railways of the USSR Ministry of Railways. During the implementation of the project, level crossings were eliminated at one level of the railway and an important city highway with heavy traffic and pedestrian traffic. As a result, the size of the car traffic has increased and its safety has increased. 

The project of a road bypass for Narva and Ivangorod with a bridge over the Narva River was developed by Lengiprotrans in the 1990s - early 2000s. During the implementation of the project, level crossings were eliminated at one level of the railway and an important city highway with heavy traffic and pedestrians. As a result, the size of car traffic has increased and its safety has increased. 

In the 1950s and later, Lengiprotrans engineers worked in the Baltics. The railway overpass at the intersection of Brassa Street in Riga was designed by order of the USSR Ministry of Railways. In places where a busy intercity motorway intersected with railroad tracks, level crossings were eliminated. Thus, traffic safety was ensured.

In the 1970s, while working in the Baltics, Lengiprotrans engineers developed projects for various transport facilities. Thus, according to the project of the institute, the reconstruction of the railway bridge across the Varduva River on the Riga — Liepaja section was carried out. The implementation of this project ensured the safe crossing of the water hazard on the railway section.
