The railway bridge over the Usu River is one of the longest in the European North. In addition, at the time of project development, it was the longest bridge designed by Lengiprotrans.
The artificial structure is part of the Synya - Usinsk line, designed to connect the city of Usinsk, the center of oil and gas production, to the country's railway communication. The bridge was commissioned before the railway line, which is an exceptional case.
The Usa River is one of the largest rivers in the North-West region of the country, with difficult hydrological and ice conditions for the passage of spring floods. The floodplain of the river at the place of crossing is swampy and has a peat cover up to 5 meters thick. Because of these features, a large amount of engineering research was carried out to select the optimal option for the construction site and bridge structures.
The bridge is designed according to the scheme 33.6 + 12x110 + 33.6 m, length 1305 m.
