Winter roads are winter roads that are temporary in nature and their construction takes place directly from the snow cover. Complex construction of roads with the use of optimizations created for temporary and economic efficiency, improving the quality of the final result, will increase the effectiveness of decisions made during the construction of winter roads. Improving the efficiency of detailed factors in the construction of winter roads, which affect the result of further work of calendar construction, will allow for faster delivery of materials, personnel and equipment to hard-to-reach objects, within the conditions of the Far North. Winter roads are the most profitable solutions in tundra conditions, since the method of using air transport to deliver materials, equipment and workers is economically unprofitable and less safe. Therefore, the timely construction of winter roads is so important for remote regions.

Every year, for the implementation of any oil and gas project in the Far North, the largest oil and gas companies use new technologies. This is due to attempts to reduce the cost of field development and operation. The article reveals the advantages of using composite materials in the construction of oil and gas fields. The cost of using composite and metal supports is given. The main objects, the construction of which is possible with the use of composites, are shown, and conclusions are drawn on the large-scale introduction of this material during construction.
