nationalväg

Nationalväg is a term used in Sweden to denote a primary national road. These roads are part of the country's main transportation network, designed for high-volume traffic and often connecting major cities and regions. Their primary purpose is to facilitate long-distance travel and freight transport across Sweden.

Swedish nationalvägar are maintained by the Swedish Transport Administration (Trafikverket). They are typically of a high standard, often featuring multiple lanes, grade-separated interchanges, and other modern road engineering features to ensure efficient and safe movement of vehicles. The designation of a road as a nationalväg signifies its strategic importance to the national infrastructure and economy.

While the term "nationalväg" is specific to Sweden, the concept of national or primary highways is common in many countries, serving a similar function in connecting key areas and supporting national connectivity. The network of nationalvägar is crucial for Sweden's internal commerce, tourism, and general accessibility.
