The Silver Road was inaugurated in 1975 when His Majesty King Harald V of Norway and His Majesty King Carl XVI Gustaf of Sweden met. A large stone block had been erected at the border. The project had been a dream for many for almost a hundred years. The road is the only Swedish national road on the bare mountain and reaches a maximum altitude of 720 metres above sea level. On the Norwegian side, however, the term Silver Road is rarely used, with E6, European Route 6, being more common. After Fauske, in the direction of Bodø, it is called RV 80. There is also another name for the 1.5 km stretch of road near Rognan: Blodsvägen/Blodsveien (Blood Road). To build the road, the German occupying forces used prisoners for labour during the 1940s. In light of this, some have argued that Silvervägen is also a kind of ‘blood road’, considering how the Swedish state used the Sami people in transport and how young men from the coast, especially during the wars of the 17th century, were forced to work in the silver mine.
