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

The second part: detailed design of twenty bridges from 157km to 217km 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
  • The flood basin is 69300 sq km
  • The width of the bridge under the bridge is 280m with the 8m depth.

The bridge is proposed to be constructed 38km away from Yakutsk City in permafrost. The length of the bridge is 2871m. Two-level combined bridge consists of 2-lane carriageway on the upper level and a single-track railway on the lower level. The total length of the river-crossing is 3180m. It includes overpass, road and railway junctions, dams, security and maintenance facilities. The river bed superstructure consists of 4x 308m-long arch spans and 2х154 + 5x(2x154)m long truss spans.
