The Suwałki Gap is a strategically important, sparsely populated area along the Poland-Lithuania border, forming the only land route between the Baltic states and the rest of the EU/NATO. Historically a relatively unimportant region, it gained prominence after the fall of the Soviet Union due to its position between Russia (Kaliningrad Oblast) and Belarus. Today, it’s a focus of military and infrastructure development, including upgrades to the Via Baltica road and the ongoing Rail Baltica project, aiming to improve connections and address security concerns. The area also features the Gas Interconnection Poland-Lithuania, enhancing energy security.Wikipedia
