Þjóðvegur 1, National thoroughfare in Iceland
Route 1 is the main thoroughfare of Iceland, forming a complete loop around the island through valleys, mountains, coastal regions, and volcanic landscapes. It connects all major settlements and serves as the backbone of the road network for travelers and residents.
Construction was completed in 1974 with the opening of Skeiðará Bridge, creating the first continuous road connection around Iceland. This achievement marked a major milestone in connecting the nation's remote regions through a single thoroughfare.
The road links isolated settlements and farming communities, shaping daily life for people who depend on its connectivity. It serves as a lifeline for regional exchange and allows visitors to experience the diverse areas of Iceland in one journey.
Winter drivers need snow tires from November to April, as weather conditions change rapidly with strong winds and reduced visibility. Check road conditions before traveling and ensure your vehicle is properly equipped for the season.
The route passes near about 30 single-lane bridges, reflecting Iceland's ongoing infrastructure modernization. These bridges were once common across the island but many have been replaced with wider structures, while some remain and add character to the drive.
