It runs between Finneid, where it branches off from European route E6, and the village of Sulitjelma, where it continues as County Road 543.

[1] The road was laid out along the bed of the former Sulitjelma Line railway, which was shut down in 1972.

Work on converting the rail route for road traffic began on July 2, 1971.

Over the course of three weeks, starting on July 24, 1972, the tracks were demolished and the road was made drivable.

The route has been proposed for protection by the Norwegian National Protection Plan for Roads, Bridges, and Road-Related Cultural Heritage.
