Route 1 was built in 1974. The road is also known as the “circular highway” because it forms a large circle that encircles the whole of Iceland. As one of Iceland's landmarks, the road is very popular with tourists. There is only one single lane on some sections of the road, passing through many bays, the subarctic desert and the Atlantic coast. Self-driving people will experience the double feeling of ice and fire. However, due to the old bridges along the roads and the lack of asphalt on some sections, it also adds a lot of difficulty to self-driving.
