In the 1980s, Lengiprotrans began developing a project for the Obskaya - Bovanenkovo ​​line, the northernmost railway in the world. The road was intended for the development of the Bovanenkovskoye and Kharasaveyskoye gas fields on the Yamal Peninsula. With the onset of the economic crisis at the end of the 1980s, the pace of track-laying dropped significantly. In 2004, the Yamal Engineering Center was established to resume construction. In 2010, the Obskaya - Bovanenkovo ​​railway was put into operation.

A large number of artificial structures were built on the railway line, including a bridge over the He-Yakha River. The length of the structure is 470 m.
