Assembly of metal structures of the superstructure was carried out by semi-weight method.
In the course of construction, as part of the implementation of the object, work was performed on:
- concreting of reinforced concrete structures – 1297 m3
- assembly of metal structures of the superstructure – 615 t
- laying of the upper structure of the path – 1.1 km

The project involves the reconstruction of 53 artificial structures located on the sections Korsakov-arsentyevka (21 bridge), arsentyevka-Buyukly (31 bridge and 1 culvert).
Construction of bridges is carried out:
- on a constant crawl;
- on an existing axis;
- on the existing axis with the organization of movement during construction on a temporary bridge and bypass..
At the moment, railway traffic has been launched on new spans on 45 bridges. Construction and installation works are being carried out on the other objects.
