The first part: detailed design of nine artificial structures across the rivers and streams from 72km to 122km of the road.

The bridge across the Amga River is located on the railway road Berkakit – Tommot-Yakutsk, in the area of permanently frozen soil. The Amga River is the largest confluent of the Aldan River and characterized by the following:

• The length is 1462.0km
