Yuribey Bridge

About

The Yuribey Bridge 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.
