The Yuribey Bridge (Russian: Юрибей) is a 3.9-kilometre long (2.4 mi) railway bridge on the Obskaya–Bovanenkovo Line. It has two main spans of 150 metres (490 ft). The bridge was completed in 2009. It is the longest bridge above the Arctic Circle.
The bridge was constructed by Gazprom in a harsh environment including the need to build on permafrost, which required an innovative approach to the construction technique and bridge design. The bridge has to be much longer than the river width, because on permafrost, the water from melting snow does not sink into the ground, so the spring flows get quite strong.
Construction of bridge
According to media reports, the bridge was built in 349 days - in a very short timeline for such structures. In April 2009, construction of the bridge was completed, and June 4, 2009 the bridge passed the first high-ranking passengers - the presidential envoy in the Urals Federal District Nikolai Vinnichenko, Governor of Yamal Jury Neyolov, CEO Gazpromtrans Vyacheslav Tyurin . The opening of the bridge allowed to complete the construction of the railway to the Bovanenkovo and begin development of the Bovanenkovo oil and gas condensate field.
The construction of the bridge was carried out with the use of modern technology on high stilts and without the traditional dumping ground, which made it possible to preserve the ecosystem of the river, without causing harm to the northern breeding grounds of fish species. To ensure the stability of the pillars in the permafrost were drilled hole depth of 20–40 meters.
