valtaväylien
Valtaväylien, a term of Finnish origin, broadly translates to "main routes" or "arterial routes" and refers to significant transportation corridors within a country or region. These are typically major roads, railway lines, or waterways designed to carry a high volume of traffic and connect key population centers, industrial areas, or economic hubs. The concept emphasizes the strategic importance of these routes for facilitating commerce, travel, and national connectivity.
In Finland, "valtaväylät" specifically denotes the primary national road network, including the E-roads that extend internationally.
