Sakhalin Region is a unique territory of Russia, since its territory is a system of islands with the main territory of about. Sakhalin and the islands of the Greater Kuril Ridge. Due to the island nature of the territory, the main problem limiting its development is the lack of a permanent transport connection with the mainland.
The transport connection of the region with the rest of the country (as well as between the islands of the region) depends on weather conditions and is carried out by air and sea transport, which makes it difficult and expensive to move people, and also limits the use of the region's resource potential due to high transport costs. The solution to the problem will be the planned construction of a bridge on about. Sakhalin, which will ensure the connection of the main developed part of the region with the country's transport system.
