Due to the economic and technical progress of countries and regions in Europe, the necessary and possible transport communications, power lines (power lines), various pipelines and other linear structures were laid through the Alpine Mountains. The Caucasian Mountains in this part are strongly lagging behind. The railway crosses the Main Caucasian Ridge (MCR) only in the western part up to the Black Sea coast, and the automobile road is in the Central part through the Cross Pass along the Georgian Military Highway and the Roksky Pass along the Military Ossetian Road. The Gas pipelines and power lines were laid in the same areas. At the beginning of the 11th century, the Dzuarikau - Tskhinval pipeline was laid to provide gas to the population of South Ossetia. In the peak position this gas pipeline is the highest one on a global scale being of a particular organizational interest. Of the same interest is the construction of a road through the Roksky Pass, hereinafter referred to as Transkam. Organizationally, these two linear structures had to be laid on the automobile road as a temporary one and a technologically advanced soil and gravel road on the gas pipeline at an absolute height of more than 3,000 meters. These roads have important social, economic, agricultural and strategic importance which is considered in this article.
