The Selfors Bridge over the Ranelva river on the E6 highway connects Selfors with the town of Mo i Rana. The first bridge at Selfors was built in 1914. On 18 May 1940, it was blown up by the resistance in order to slow down the northward advance of the German occupation forces. It was, however, quickly rebuilt, and was used until it was torn down on 17 March 1965. A new bridge was then built, and is still in use today.
