What transportation corridors did Russia build and why?

Russia built several key transportation corridors to enhance connectivity and facilitate trade, particularly through its vast territory and to international markets. Notable corridors include the Trans-Siberian Railway, which links Moscow to Vladivostok, and the Northern Sea Route, which connects Europe to Asia via Arctic waters. These corridors aim to boost economic development, improve logistics, and strengthen geopolitical influence by enhancing access to remote regions and fostering trade relationships. Additionally, investments in road networks and ports support regional integration and the movement of goods across borders.
